Latest Patents
Pirot's latest patents include a copy-protected optical disk and a protection process for such a disk. This invention relates to an optical disk that features at least one spiral track with information marks written in sequential sectors. The disk incorporates a copy protection zone (PZ) that consists of two equal parts, each containing a series of sectors with identical addresses. This innovative design allows for shared data between the sectors, along with specific protection data to verify the integrity of the protection zone. The invention is particularly applicable to anti-piracy protection for CD-ROM and DVD-ROM disks.
Another significant patent is the anti-chipping recording disk, which features a main recording track with interruptions or changes in direction. This design results in non-sequential reading, making it challenging to access the information. Consequently, copying such a disk through conventional means becomes very difficult, allowing for easy detection of counterfeits and rendering unauthorized copies unusable.
