Latest Patents

Hirashima holds a patent for an information regenerating apparatus. This apparatus is designed to read recorded data, which consists of a sector mark followed by a header section containing multiple data sets. Each data set includes a pull-in pattern, an address mark, and address information. The device generates a regenerative signal that is utilized to regenerate information. A phase-locked loop circuit within the signal synchronizing circuit performs phase synchronization with the regenerative signal at two different pull-in speeds. The speed indicating circuit counts clock pulses from a reference clock signal, instructing the phase-locked loop circuit to adjust its response speed based on the presence or absence of the pull-in pattern.
