Sony
announced today that they have developed "Postscribed ID for DVD." With this new technology, companies will be able to embed ID data,
like serial numbers, into DVD's during the manufacturing process.
"Postscribed ID for DVD" makes read-out of individual
IDs embedded in DVD discs possible using standard DVD-ROM drives, without the need for firmware updates or any other software
installation. Furthermore, the newly developed technology does not infringe the powerful error correction features present in the DVD
format. This allows the same CD-ROM-based serialization services to now be offered on DVD-ROM media.
By using a high-power laser diode, new reflective layer material, and extremely
accurate location control technology, the area between pits on the disc surface is modified to embed the ID data. This in turn allows for
compliance with the powerful error correction technology built-in to DVDs and adheres to the DVD Format (DVD Specification for Read Only
Disc). The EFM signal used for direct recording of serialized ID data is based on advanced technology for preventing any impact on
pre-recorded data when recording the ID onto the disc, effective write-strategy and a special reflective layer.
