Disc Identification/Serialization Data

The Identification & Serialisation Data from a PlayStation 4 Game Title contains several Informations, which you can find not only on any Game Disc pressed for the PlayStation 4, but also similar for any PlayStation 3 or any other Console-based Disc Game and other Media pressed on CD, DVD and on Blu-ray.

Title ID Spine Code

The Title ID (there is no official name about this numeric coding from Sony) defines a internal numeric coding system and can be compared to a part/catalogue number or a ISBN number on a book. With this code, which every Game contains, it is possible to identify every Game whichever released. Sony used already this system for releasing their Games on PlayStation, PlayStation 2 and PlayStation 3, both for disc-based games and for their digital pendants, released in the PlayStation Store.

While Sony used different codes for different region areas in Japan, North America, Europe, Hong Kong and Asia for their games released on PlayStation, PlayStation 2 and PlayStation 3, it seems that there were no regional differences on games released for the PlayStation 4 in general, but every game use another codes compared to the same game released in another region. Also it seems that there are no differences from Games released directly from Sony Computer Entertainment (First Party) or from Third party developers (Licensed). And for this time, released Games for the PS4 shares the same code both on the pressed disc game version and for the digital version released in the PlayStation Store.

You can find these codes on several positions for example printed in the spine from a Game cover and printed on the top of the pressed Disc but also located in the PARAM.SFO and probably used as a folder structure for Games installed on the Harddrive.

Examples

• Games released for the PlayStation 4 contains a numeric coding system in the format "CUSA-XXXXX" (while the "XXXXX" contains a 5-digit-code for every released game).

• For the regional differences, every game shares the same "CUSA-XXXXX" format, but for example the european Version from the Launch Title "Killzone: Shadow Fall" are listed with the "CUSA-00002" code, while the North American version from the same game are listed with the "CUSA-00190" code.

• About the difference between First party released Games or Licensed, Games released directly from Sony Computer Entertainment (SCE) for the PlayStation (2) are listed in the "SCES-XXXX" format, while Games directly released from Sony for the PlayStation 3 are listed with the "BCES-XXXX" code (in this example from Sony Computer Entertainment Europe (SCEE)). Other Third party Games are listed with "SLES-XXXX" (for PlayStation (2)) and with "BLES-XXXX" (for PlayStation 3).
• But it seems that all Games released for the PlayStation 4 will use the same "CUSA-XXXXX" format (Killzone: Shadow Fall, european Version = "CUSA-00002" & FIFA 14, european Version = "CUSA-00128"), while the european Version from Killzone 3, released for the PlayStation 3 are listed with the BCES-01007 instead of a BLES-XXXXX format).

• Games released both on disc and in the PlayStation Store shares the same Title ID (european PSN-Versions from Killzone: Shadow Fall = "EP9000-CUSA00002_00-KZ4RELEASE000041" and FIFA 14 = "EP0006-CUSA00128_00-FIFAFOOTBALL2014").

Notes

There is a good overview in the PS3 Section about the Title ID where you can imagine how easy the new numeric coding system works on the PS4 now.

It is also unknown if Game Saves from a disc-based Game works also for the PSN version.

Source Identification Code

The Source Identification Code (SID-Code) is foundable on almost all pressed optical discs worldwide since 1994, originally planned as a piracy safeguard, but it's also used as a quality control measure. It contains two Codes, one Mastering Code and one Mould Code (replaced on PlayStation 4 Game Discs with the PS4 logo). Each Code consists the digits “IFPI” (named by the International Federation of the Phonographic Industry) followed by a four or (less often) five digit code (commencing with the letter “L”). These two codes can be used to trace the location from a manufacturing or mastering plant where the disc got pressed. The Mastering Code is located in the innering from any optical Disc outside the datasection.

Mastering plant SID Codes

Region (Suffix)	SID-Mould Code	SID-Mastering code(s)	Mastering plant	Country	Disk type	Remark
Europe (04)	IFPI 94**	IFPI L551 to IFPI L560	Sony DADC Austria AG	Austria	PSX/PS3/PS4?	Thalgau, near Salzburg
Europe (04)	IFPI LY**	IFPI LZ08	QOL Fi Group	France	PS4	IFPI LY25 = CUSA-00002 (Killzone: Shadow Fall) & IFPI LY26 = CUSA-00128 (FIFA 14)
Europe (04)	IFPI L5**	?	Sony DADC Austria AG	Austria	PS2	Anif, near Salzburg

Burst cutting area

The (narrow) burst cutting area ((N)BCA) can be used for adding additional information such as serial numbers or any information about the manufacturing process etc. The BCA-code is written using a Nd:YAG laser and can be also used as a security measure to avoid illegal copies from a pressed disc (for example on game discs for the Nintendo GameCube, Wii and Wii U). Therefore it isn't possible to reproduce/copy the BCA with a standard optical disc drive running on a PC/Laptop.

• Location: innerring inside datasection
• Radius: 1.2 mm (zone between 22.3 ±0.4 mm to 23.5 mm ±0.5 mm (single-layer), 21.0 ±0.4 mm to 22.2 mm ±0.5 mm (dual-layer))
• datasize: 12 bytes (minimum) to 188 bytes (maximum) (in steps of 16 bytes)

Sometimes blank recordable & rewritable discs (such as DVD-R/RW/RAM, BD-R/RE/XL) uses also a BCA-code were informations about the CPRM and other DRM-policies were stored.

On Blu-ray discs a Pre-recorded Media Serial Number (PMSN) can be stored in the BCA (but extremly unlikely on PS3/PS4 game discs because this was a part from the AACS copy protection).

PIC Zone

This (pre-recorded) PIC zone, which is included within the BCA (Datasize: 0x73 bytes), contains general information about the disc that includes, but is not restricted to:

• Physical media class and version,
• Physical address of the start of the Data Zone
• Physical address of the start of the outer zone (if this is a single layer media, this is the lead-out)
• Number of layers
• Recording Density
• Write power information

Angular Marks

Angular Marks

Angular Marks are also a security measure to avoid piracy. It works similar to the BCA but with the difference that these Marks were located in the data area of a disc/outside the BCA. It can be compared to the old Bad Sector copy protection, were the CD-ROM got pressed with zero-filled Physical Sector Numbers, which are unreadable for some writers without RAW writing function.

It is known that Sony (Pictures Entertainment) use these Marks to avoid illegal copies on Blu-ray Movies (which is easy to bypass), but there are no informations about the application on PS3/PS4 game discs pressed on BD-ROM.

ROM Mark

ROM Mark or BD-ROM Mark is a serialization technology designed to make it more difficult for replication plants to do unlogged over-runs (being sold out the back door, without the copyright holder's knowledge) on a pressing.

Only licensed BD-ROM manufacturers have access to the equipment that can make these unique ROM Marks (physical-layer to store key cryptographic secrets).

Although every machine used to laser-cut a master disc is theoretically the same, the motor that spins the blank disc and moves the laser along a spiral track varies slightly in speed and precision. So if a digital marker is put in the middle of a recording, its physical position on the master disc - and every disc then pressed - will be a unique fingerprint of the cutting machine.

The ROM Mark contains the Volume ID required to decrypt content encrypted using AACS.
