Latest Patents

Kikuno's latest patents include systems and methods for forming a master disk utilizing variation in an applied signal power for forming uniform pits. This recording method involves the use of an inorganic resist made of an incomplete oxide of a transition metal, which is formed as a film onto a substrate. A latent image corresponding to pits is created on the inorganic resist through exposure. The exposure is performed by a laser beam whose intensity is modulated by a pulse signal, resulting in a track pitch smaller than the recording beam diameter, specifically with a ratio of track pitch to exposure beam diameter ranging from 0.333 to 0.833. Another significant patent is for a high-density optical disc that employs a similar recording method, further enhancing the capabilities of optical storage.
