Latest Patents

Sugiyama's latest patents include a "Linking gap detecting device and method of optical recording medium." This invention involves a light beam that is irradiated onto an information recording track of an optical recording medium. A light detecting signal is generated by receiving the reflected light, and a synchronous signal is detected from this signal. The device judges whether the existing interval of the synchronous signal lies outside a predetermined range, allowing for the detection of linking gaps based on the judgment results.

Another significant patent is the "Apparatus and method for re-executing pre-pit detection if pre-pits are not detected after changing reference level." This invention pertains to an information recording/reproducing apparatus that irradiates a light beam on an optical disc with pre-pits. It performs recording and reproduction of information based on a recording clock produced from wobble and pre-pit signals. If a pre-pit is not detected, the reference level is adjusted, and the detection process is executed again.
