With a total of 4 patents to his name, Sugihara has developed innovative solutions that enhance the recording and reproduction of digital audio information.
Latest Patents
One of Sugihara's latest patents is focused on a read-only digital audio information recording medium. This invention features a spiral recording track that includes multiple record unit blocks formed through an optical recording method. Each block consists of a dubbing permitted area and a dubbing inhibited area. The digital audio information, which contains compressed data, is recorded in the permitted area, while display data associated with the audio is stored in the inhibited area. This design allows for digital dubbing of audio information while preventing the dubbing of display data, ensuring the integrity of the read-only disc as a master software.
Another notable patent is an audio data recording and reproducing apparatus that operates at high speed. This apparatus intermittently records and reproduces compressed digital audio data during normal operations. For high-speed dubbing, two such devices are utilized. The reproduction side continuously plays back compressed digital audio data from a disc, which is then directly applied to the recording side for continuous recording. This method achieves compressed high-speed dubbing without increasing the rotation speed of the disc.
