The processing key and disc volume id key is then processed using AES algorithm to obtain the Volume unique key. Having the
Volume unique key allows decryption of the disc's encrypted title key, which results in the unencrypted title key. The
unencrypted title key can decrypt the disc's encrypted movie.
Regular protection for Blu-ray games
Blu-ray games (PS3 games) do not use AACS. However, PS3 games do use the BD-ROM mark to store decryption keys on the
Blu-ray disc. Each PS3 Blu-ray game normally includes a firmware update file (PS3UPDAT.PUP) to update a PS3 that does not
have internet access. The version is normally the minimum PS3 firmware version needed to run the Blu-ray game.
The directory layout on Blu-ray games are as follows:
• PS3_GAME
o userdir
o ICON0.PNG
o ICON1.PAM
o PARAM.SFO
o PIC1.PNG
o PS3LOGO.DAT
o SND0.AT3
• PS3_UPDATE
o PS3UPDAT.PUP
• PS3_DISC.SFB
Blu-ray Chips
The drive controller contains a BGA-sized 2MB flash memory chip for Blu-ray drive firmware code, with the contents encrypted.
In addition to this, there is a 8MB SDRAM working memory chip. Each drive contains a unique identification number, possibly
stored in the SPI Serial Interface NOR Macronix flash chip.
This chip or the flash chip probably stores the device key (and associated sequence keys), and the host private key. The Blu-ray
drive's controller board is coupled with the PS3 it came in, so you cannot swap Blu-ray drives (along with its controller) into
another PS3 without having the identification numbers corrected on the controller of the drive (and/or motherboard of the PS3).
You can, however, remove just the drive (without controller) and swap it into another PS3 without problems as long as the
drives are similar.
The Blu-ray drive is controlled by the Sony CXD5065 Digital Signal Processor chip and the Sony CXA2720 Front End Processor
chip. Motors are driven by Rohm BA5888FP and Rohm BD7956FS.

Blu-ray Lens
Note that the lens in the Blu-ray drive went through various evolutions as newer PS3 models were released. Many of the initial
40GB models (CECHG) used a cheaper version of Blu-ray lens, which had a high failure rate, requiring replacement.
