Latest Patents

One of Nai-Heng Tseng's latest patents is titled "Recordable optical recording medium containing preinstalled information, the method of reading the same, and the circuit thereof." This invention discloses a recordable optical recording medium that features a substrate with a spiral pregroove. The pregroove is designed with regular wiggles, incorporating a first, second, and third waveform that share the same fundamental wave cycle. The distinct duty cycles of these waveforms are utilized to record preinstalled information. The invention also outlines a method and circuit for reading this information, which includes phase corrections, integrations, and resetting to accurately retrieve the preinstalled data.

Another notable patent is "Optical discs with controllable access times and method of the same." This method allows for the control of access times of optical discs. It involves obtaining addresses of a life flag and a medium key block (MKB) by reading a private flag of the optical disc. The life flag and MKB are crucial for managing access times. The optical disc drive determines the appropriate reading power to access the MKB, thereby reducing the recognizable number of access times in the data.
