Latest Patents
Hirai's latest patents include an innovative optical disk capable of disabling incompatible recorders. This optical disk is designed to work with specific recording apparatuses that utilize an optical beam to create pits along the pregroove for information recording. It is engineered to be incompatible with other recording devices that perform test recordings in a conventional optical disk's count area. The disk features a test area and a prepit area, which are strategically designed to prevent unauthorized recording attempts.
Another significant patent is for an optical disc reading device. This device ensures that data read from an optical disk is efficiently written into a RAM in response to a reproduced clock signal. It includes a decoder circuit that detects any Run-out block during the data link period. Upon detection, a timing resetting circuit adjusts the write and read pointers in the RAM to maintain a predetermined distance, thus preventing overflow or underflow issues during optical scanning.
