Disc Identification/Serialization Data

If the discs are made unique or serialized such that a typical readout device can identify the unique information, many optical disc applications can be enhanced or made more secure.

IFPI Code

International Federation of the Phonographic Industry

synonym: SID-Code (Source IDentification Code)

Used for marketing strategy, quality control and Anti-Piracy Compliance Program, there are two kinds of codes: a Mastering Code and a Mold Code. These 2 codes can be used to trace the location where discs are made.

Each Mastering SID Code that is assigned will consist of the digits “IFPI” followed by a four or five digit code commencing with the letter “L”.

Mould SID Code will consist of the letters “IFPI” followed by a four or five digit code.

The first two digits (in the case of a four digit SID Code) or the first three digits (in the case of a five digit SID Code) are assigned to the operator of the manufacturing or mastering plant. The last two digits of this code are allocated to give each mould on the site.

Using alphanumeric digits consisting of the numbers 0 through 9 and the letters of the Western alphabet A through Z,excluding “I”, “O”, “S” and “Q”, the plant has the ability to assign unique codes to 1,024 different mould code.

Cutting Burst Area (CBA)

synonym: Burst Cutting Area (BCA), Narrow Burst Cutting Area (NBCA)

The BCA is used to add unique information, such as the serial number, to the individual disc after completion of the manufacturing process. The BCA–code is recorded in CAV mode. Then BCA-code is written as a series of low-reflectance stripes arranged in circumferential direction.

The zone between radius 21.0 mm and 22.2 mm is reserved to be used as an optional BCA.

• location: innerring inside datasection
• radius: 22.3 to 23.5mm
• datasize: 12 bytes to 188 bytes in steps of 16 bytes

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.
