Editing CDVD Drive

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

* GM-038 (early A-chassis) (SCPH-10000, early SCPH-15000, DTL-T10000)<br/> [[File:O2kHeUP.jpg|200px]]

** Contains RF-amp (Sony CXA2605R)

* GM-041 (B-chassis, B'-chassis) <br/> [[File:ijlZhMf.jpg|200px]]

** Contains RF-amp (TI SP3727A) and tilt-driver (BA5912AFP)

* GM-042 (late A-chassis, A+ chassis) (late SCPH-15000, GH-003 based SCPH-18000)<br/> [[File:ayV4TIz.jpg|200px]]

** Contains RF-amp (TI SP3727A)

** does not require any heatsinking, unlike GM-038 used in the same chassis; a hole in the case to place a thermal pad in is still there in these consoles, but the thermal pad has been left out from the factory

* GM-043 (C-chassis, C'-chassis) <br/> [[File:cRFTRP8.jpg|200px]]

** Contains RF-amp (TI SP3727A), spindle driver (BA6664FM) and focus/tracking/sled-motor/tray-motor driver (BA5810FP)

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.

==== A/A+ chassis drive block ====

''SCPH-10000 japanese launch consoles, SCPH-15000 consoles, some SCPH-18000 consoles, all japan only''<br/>

* 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 ====

''north american early/launch SCPH-30001 consoles, north america only''<br/>

* 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 ====

 

 

** 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)

''SCPH-500xx consoles in any region, SCPH-550xx special editions in some regions''<br/>

* 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)

 

=== Slim drive assemblies ===

''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

** [[PVR-802W|KHM-430(A)]] pickup ''(has only "KHM-430" embossed in it's base)

* KHM-430BAA

** [[PVR-802W|KHM-430B]] pickup

 

** [[PVR-802W|KHM-430C]] pickup

 

** [[PVR-802W]] pickup

** [[PVR-802W]] pickup

** [[PVR-802W]] pickup

 

** [[PVR-802W]] pickup

''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.''<br/>''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

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.

** Uses Sony [[KWS-200A]] optical pickup (in addition to a [[KHS-400C]])

** Uses Sanyo [[SF-DB11]] optical pickup (in addition to a [[KHS-400C]])
