GENERAL

The SID Code is imprinted in the inner area of CD and high density optical discs. The SID Code consists of the letters “IFPI”, followed by either four or five additional characters, which may be alphabetical or numerical, identifying the registered number of the LBR used to make the glass master or stamper, or the registered number of the mould used to press the disc. There are two kinds of SID Code, the Mastering Code and the Mould Code.

  • The Mastering Code must be installed and applied strictly in accordance with the section below entitled “Mastering SID Code: Technical Specifications” which includes the requirement that it must be recorded by the LBR (Laser Beam Recorder) on to the surface of the glass master or stamper so that it is reproduced on every metal manufacturing part and hence every disc produced from that master or stamper. The SID Code must be installed in such a way that it is not capable of being altered or disabled by the user of the LBR, i.e. it must be hardwired into firmware of the LBR or embedded to the system controller.
  • The Mould Code must be installed and applied strictly in accordance with the section below entitled “Mould SID Code: Technical Specifications” which includes the requirement that it must be etched on the mirror block surface of every mould. It is not acceptable to etch the mould on any removable ring. When a substrate is pressed, the Mastering Code must be recorded on the same side of the substrate on which the embossed data pits are recorded, and the Mould Code must be recorded on the other side of the substrate.

Mastering SID Code

Mastering SID Code: technical specifications

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”. A manufacturer will be assigned a batch of sequential codes and must assign a unique code to each separate LBR on the site. The Mastering SID Code must be added to the matrix band of the master during exposure on the LBR. All subsequent metal manufacturing parts (including mothers and stampers) and all discs manufactured from that master will then bear the code. The LBR supplier will be able to install this once advised of the specific code allocated to each LBR.

The Mastering Code must:

  1. Be positioned between 18.0 mm from the centre of the disc and the start of the “lead-in” (which is at a radius of 22.9 mm from the centre).
  2. Be a minimum of 0.5 mm high.
  3. Be legible without magnification.
  4. Be located in the metallised region of the disc.
  5. Read from left to right when viewed from the read-out , or play side of the disc.
  6. Be installed in either the firmware of the LBR (i.e. the software that forms an intrinsic part of the machinery and is not readily accessible by the operator of the facility) or embedded in the system controller (i.e. the signal processing system that controls the operation of the LBR) in such a way that the operator of
    the system is not able to alter or remove/ disable the code.
  7. It is recommended that the space allocated exclusively for the code (determined by the user and LBR supplier) shall consist of an arc of 30º for the Mastering SID Code. It is mandatory that it is clearly separate from other features.
    Additional requirements for High Density Disc Formats such as DVD and SACD.

The allocated Mastering SID Codes should be used in the production of both CD format discs, and high density disc formats. However, there are some variations in the standard for applying Mastering SID Codes to high density disc formats, as set out below.

  1. 1. The Mastering SID Code must be placed within the zone that has a maximum radius of 22.5 mm.
  2. 2. If Burst Cutting Area – Code is used, then the position of the Mastering Code should be adjusted to compensate.
  3. 3. No minimum radius is specified, but due regard should be paid to the following points:
    • The Mastering SID Code must be located in a metallised region of the disc.
    • The Mastering SID Code must not be obscured by the stack ring.
    • It is recommended that the space allocated exclusively for the code (determined by the user and LBR supplier) shall consist of an arc of 30º for the current code. It is mandatory that it is clearly separate from other features.
    • A further arc of 30º shall be reserved for future use.

Mould SID Code

Mould SID Code: Technical Specificatrions:

Each Mould SID Code that is assigned will consist of the letters “IFPI” followed by a four or five digit code. The last two digits of this code are allocated by the person to whom the SID Code has been assigned to give each mould on the site, including spare moulds, a unique 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 by Philips Intellectual Property & Standards.
Example: A Mould SID Code of  “IFPI A01xx” may be issued to the operator of a manufacturing plant. The digits “A01” are unique to the facility operator. The facility operator must then use the last two digits to allocate a unique code for each mould. The code for the first mould might be IFPI A0100, the code for the second “IFPI A0101”, and so on. 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 moulds. “xx” represents the two variable digits to be assigned by the facility operator.

The Mould SID Code must:

  1. Be etched on the mirror block of each mould, or a component of the mould that is not easily detachable from the mirror block, so that the Mould SID Code is moulded on the read-out, or play surface of each disc during the manufacturing process. The Mould SID Code may not be etched on any removable ring that is not part of the mirror surface, such as the cutter bush or ejector sleeve. The Mould SID Code may not be applied to the other (stamper) side of the disc.
  2. Be positioned at a radius of between 7.5 mm and 22 mm from the centre of the disc, except in the case of high density format discs (see section following).
  3. Have a character height of between 0.5mm and 1.0mm.
  4. Be etched to a depth of between 10 to 25 microns and be legible, without magnification, throughout the life of the mould.
  5. Read from left to right when viewed from the read-out, or play side of the disc.
  6. The digits “IFPI” must be in upper case characters and may have either a linear or a radial layout.

Additional requirements and variations for High Density Disc Formats such as DVD and SACD.

The allocated Mould SID Codes should be used in the production of both CD format discs, and high density disc formats. However, there are some variations in the standard for applying Mould SID Codes to high density disc formats, as set out below.

  1. The Mould SID Code must be positioned within the zone that has a maximum radius of 22.5 mm.
  2. If Burst Cutting Area – Code is used, then the position of the Mould SID Code will be adjusted to compensate.
  3. The Mould SID Code must not be imprinted in the clamping area.
  4. The Mould SID Code must not be placed in an area that obscures the Mastering SID Code or any other user defined characters.
  5. The Mould SID Code must be imprinted on all substrates whether containing valid programme content or not, including blank discs, and even if not metallised. Overprinting of the Mould Code for decorative purposes is permissible.

Disc variations

For the single layer, single side disc.

If the dummy side of the disc is made from a scrap program disc, it shall bear the SID Code, even if not metallised.

For the dual layer, single side disc.

The Mastering SID Code must be recorded for both layers (Layer 1 and Layer 0 in DVD format discs). At least one of the Mastering SID Codes (for either Layer 1 or Layer 0) must be clearly visible.

For the single layer, double side disc.

The Mastering SID Codes must be recorded on both sides of the disc. It is desirable that both Mastering SID Codes are clearly visible, but it is acceptable if the code is obscured due to restrictions of the printed area.

For Hybrid SACD discs (one high-density layer and one CD layer)

The Mastering SID Code must be recorded on both layers. It is desirable that both Mastering SID Codes are clearly visible, but it is acceptable if the code is obscured due to restrictions of the printed area.
