The PS2-part of the drive is based on the H/I chassis SCPH-5XXXX fat PS2 drive, both electrically and mechanically. The whole drive assembly is connected to the motherboard using 3 flat flex cables: One is an IDE connection to the dedicated drive board of the PSX-part, one provides power (5V, 12V, GND) and also connects the PS2-part sled motor to the motherboard (since it is controlled by the motherboard directly), and one connects the KHS-400C PS2-part pickup to the motherboard, since it is also directly controlled by the motherboard. The spindle motor is always controlled by the dedicated PSX-part drive electronics over IDE, even in PS2 mode.

== Optical pickup ==
=== Notes ===
* KHS-400R seems to be a rebadged Sanyo SF-HD7 with a different plastic cap to remove the "HD7" labelling present on the SF-HD7; they are completely drop-in interchangeable
* KHS-400B and KHS-400C are electrically compatible, but differ in thickness of their bases, making them mechanically incompatible (putting a KHS-400C in place of a KHS-400B will seem to work at first, but the flex cable will bend heavily once the pickup reaches the outer area while moving)
* KHS-400C and KHS-400R / SF-HD7 are mechanically fully compatible, but require different calibration data for [[MechaCon]]
* There are 2 different lens assemblies for KHS-400B, which require different calibration data for MechaCon: T487 (white ring around lens) and T609K (yellow ring around lens). T609K seemingly was introduced with the D/D'-chassis. Some early T609K have a white ring around the lens. These pickups have a violet marking at the adjustment screw. (Markings in other colors don't indicate any lens assembly variant, only violet does)
* KHS-400B (with T487 lens assembly) can fully drop-in replace KHS-400A, but not vice versa (mechanical reasons: KHS-400A in a drive meant for KHS-400B can't press the home-position switch near the spindle). KHS-400B with T609K lens assembly can also be used, but requires different calibration data for MechaCon.
* PSX consoles always have 2 pickups: One KHS-400C (for PS2 games only) and KWS-200A (XPD-001 motherboard) or SF-DB11 (XPD-005 motherboard). Every disc will first be detected by the KWS-200A / SF-DB11, so if this pickup is broken, the console also won't read PS2 games, since the KHS-400C only becomes active once a PS2 game has been detected
* The drive mechanisms of earlier and later PSX consoles are completely different from each other (except the KHS-400C), so you can't replace a KWS-200A with a SF-DB11 or vice versa
* PVR-802W and KHM-430 seem to be mostly identical; KHM-430 is probably a rebadged PVR-802W, as it is with KHS-400R / SF-HD7
* Several revisions of the Sanyo SF-DB11 pickup exist, with only the older ones being compatible with the PSX. Trying to install a newer one will burn the flat flex cable and/or blow the 5V drive-power fuse on the motherboard depending on your luck (known compatible revisions: T02, T05, T06, bottom sticker number starts with DB11; known incompatible revisions: T09, T14, bottom sticker number starts with 11NX). It didn't seem to damage anything else though; most notably all electronics (after replacing the blown fuse) AND the laser pickup (after being installed into a compatible PC drive that uses this newer revision) survived.

Overview[edit | edit source]

The drive is known as MD-block in internal Sony documentation, where MD stands for "Mechanism Deck". For the optical pickup ("Laser"), see Pickups.

Electronics[edit | edit source]

Early consoles (A, A+, AB, B, B', C, C' chassis) have separate boards with some of the disc drive electronics:

  • GM-038 (early A-chassis) (SCPH-10000, early SCPH-15000, DTL-T10000)
    O2kHeUP.jpg
    • Contains RF-amp (Sony CXA2605R)
    • requires heatsinking for RF-amp

The PSX also has a dedicated board for drive electronics, which contains all drive components for the PSX/DVR-mode/burning part of the PSX's unique dual-pickup drive. Electronics for the PS2-part of the drive are however on the mainboard (spindle motor control and driving are always handled by the PSX/DVR part of the drive).

  • Uses a different knob
  • The only drive block to use the KHS-400A pickup, later units use KHS-400B (a picture of a drive inside a SCPH-18000 A+ chassis console using the KHS-400B pickup has been added above)
  • Later units have a slightly different drive board which contains a Texas Instruments SP3727A RF-Amp instead of the Sony CXA2605R RF-Amp that was used on early units
  • In these pictures, the flat flex cable between the board and the laser unit has been replaced. The only difference to the original cable is the length of the blue flap, which is longer on the original cable on the side connected to the PCB

B/B' chassis drive block[edit | edit source]

  • Uses a 60 teeth white knob
  • Uses a radial tilt control motor only found in this drive block; all other drive blocks have their radial tilt mechanically set at the factory
  • Optical pickup is always KHS-400B

C/C' chassis drive block[edit | edit source]

Gov1HNg.jpg5kfnZit.jpgGLVqrNi.jpgKncxtr7.jpgIEjTkZ5.jpgFVtodEz.jpgBJfmUzT.jpg

  • Uses a 60 teeth white knob
  • Takes away the tilt motor introduced on the B/B' chassis drive block
  • Has both driver ICs on the drive board
  • Has an aluminium plate mounted as heatsink between the drive board and drive frame which thermally connects to the back of the PCB through a thermal pad, however, the ICs are also directly cooled from the other side through a thermal pad connecting them to the expansion bay frame

  • Uses a 60 teeth white knob
  • Basically a C/C' chassis drive block with a different drive board that only contains the RF-amp but not the driver ICs, since these are located on the motherboard, and no heatsink. Also some slight mechanical differences in the plastic casing.

D/D' chassis drive block[edit | edit source]

  • Uses a 60 teeth white knob
  • all drive electronics moved to the motherboard, no dedicated drive board anymore

F/G chassis drive block[edit | edit source]

  • Optical pickup changed to KHS-400C or SF-HD7
    • Pictures show the variant that uses the Sony KHS-400C pickup. Variants using the Sanyo SF-HD7 pickup are identical aside of the pickup itself; the pickups are interchangeable (different calibration data for Mechacon required, use LensChanger or PMAP)

H/I chassis drive block[edit | edit source]

Un3LrqS.jpgN13dm9Y.jpgJ5g8RtO.jpgFLt0xfo.jpgY0SF82K.jpg2EeoJVp.jpg4sSITOE.jpg

  • Pictures show the variant that uses the Sanyo SF-HD7 pickup. Variants using the Sony KHS-400C pickup are identical aside of the pickup itself; the pickups are interchangeable (different calibration data for Mechacon required, use LensChanger or PMAP)
  • Some markings on the mechanism have been made by the owner during alignment; they are not from the factory
  • Button assembly now mounted on the drive assembly
  • Mechanical changes:
    • Tilt of the two rods that the optical pickup slides on can be adjusted individually
    • Slide arm of the optical pickup now made of a metal spring instead of plastic

J chassis drive block[edit | edit source]

late SCPH-5xxxx consoles in some regions
IrvUNi2.jpgJ5KaXJn.jpgUIrCwhc.jpg

  • Very different drive:
    • Uses Mitsumi TDP062W drive mechanism based around the Mitsumi PVR-702W pickup

Slim drive assemblies[edit | edit source]

  • Some of the slim drives exist with different cable lengths for different chassis. K-chassis and L-chassis use same cable length between each other, as do P-chassis and R-chassis between each other. M-chassis and N-chassis both use different cable lenghts. This makes a total of 4 slim PS2 drive "types" regarding cable length.

Sony assemblies[edit | edit source]

The Sony assemblies are identical to and fully compatible with their Mitsumi-counterparts from the same chassis. The only difference is the branding.

  • KHM-430AAA
    • K-chassis, L-chassis
    • KHM-430(A) pickup (has only "KHM-430" embossed in it's base)

KHM-430BAA top.jpg KHM-430BAA bottom.jpg

  • KHM-430CAA
    • N-chassis, P-chassis, R-chassis
    • KHM-430C pickup

KHM430CAA top.jpg KHM430CAA bottom.jpg

Mitsumi assemblies[edit | edit source]

The Mitsumi assemblies are identical to and fully compatible with their Sony-counterparts from the same chassis. The only difference is the branding. Not found in R-chassis consoles.

  • TDP082W

TDP082W top.jpg TDP082W bottom.jpg

  • TDP182W (with M-chassis compatible cable length)
  • TDP182W (with N-chassis compatible cable length)
  • TDP182W (with P-chassis compatible cable length)

Sankyo/Philips assemblies[edit | edit source]

The Sankyo assembly is incompatible with the Sony/Mitsumi assemblies. It requires different top shells for the case and different MechaCon calibration data. Only found in K and L-chassis consoles.
While Sankyo is confirmed as the manufacturer of the whole assembly, the actual laser pickup might be manufacturerd by Philips, as SPU3170 would be consistent with their naming scheme for pickups and Sankyo was never known to produce pickups, since their expertise lies within electromechanical systems.

  • SPU3170
    • K-chassis, L-chassis
    • This is likely the name of just the optical pickup, not the whole assembly

PSX drive assemblies[edit | edit source]

The PS2-part of the drive is based on the H/I chassis (SCPH-50000/55000) PS2 drive, both electrically and mechanically. The whole drive assembly is connected to the motherboard using 3 flat flex cables: One is an IDE connection to the dedicated drive board of the PSX-part, one provides power (5V, 12V, GND) and also connects the PS2-part sled motor to the motherboard (since it is controlled by the motherboard directly), and one connects the KHS-400C PS2-part pickup to the motherboard, since it is also directly controlled by the motherboard. The spindle motor is always controlled by the dedicated PSX-part drive electronics over IDE, even in PS2 mode.
