Title: Tooru Fujishima: Innovator in Optical Video Technology
Introduction
Tooru Fujishima is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of optical video technology, holding a total of 7 patents. His work primarily focuses on enhancing the functionality and efficiency of optical disc players and recorders.
Latest Patents
Fujishima's latest patents include a control apparatus for optical video disk recorder/player. This innovative control apparatus is designed to manage the optical recording and reproduction of video and audio information on a recording medium using a light beam. It features a tracking failure detection circuit that identifies when the light beam fails to accurately track along a designated track on the recording medium. In response to this detection, a light beam control signal generator circuit reduces the energy of the light beam, thereby inhibiting the recording of information in the event of a tracking error.
Another notable patent is the control apparatus for an optical disc player that locates blank tracks. This optical disc player is capable of optically recording video or audio information onto a recording medium or reproducing the recorded information. It includes a search unit that identifies unrecorded information tracks before adding new information signals. The search unit utilizes a level detection circuit to assess the energy value of light reflected from the recording medium, ensuring that recording occurs only on tracks that have no prior signals.
