As part of new licenses and as part of settlement of disputes, manufacturers are now required to sign a side-letter setting forth the mandatory LSCD requirement. Such side-letters are also available to existing manufacturers wishing to demonstrate to their customers that they will only ship products covered by a valid LSCD issued by Philips. Manufacturers with this requirement are listed on Philips Licensee database with an asterisk (*). For more information about LSCD’s please visit our Supplier/Buyer page.

What is the SID code?
The CD replication industry developed a code system (SID code also known as IFPI code) to be employed by CD, DVD & SA-CD manufacturing plants to identify all discs mastered and/or replicated in their plant. Each CD-, DVD- and SA-CD manufacturing facility around the world has their own unique code and this enables the music industry to trace the origin of CDs.
The Source IDentification Code (SID Code) provides an optical disc production facility with the means to identify:
- all discs mastered and/or replicated in its plant;
- and the individual Laser Beam Recorder (LBR) signal processor or mould that produced a particular stamper or disc.
Each production facility that wishes to implement the use of the SID Code is issued with its own unique code(s). The SID Code was developed for use with the CD format, but is now being used for both CD and High Density disc formats, including DVD and Super Audio CD.
The SID Code was developed jointly by rights owners and the optical disc industry, primarily as an anti-piracy tool. However, since its introduction in 1994, the SID Code has proved a major benefit to optical disc producers. Its use both as a quality control tool and as a marketing tool has ensured that the SID Code, which was introduced on a purely voluntary basis, has now been implemented in over 80% of the world’s optical disc plants, representing over 90% of worldwide optical disc manufacturing capacity.
