Latest Patents

Noritaka Narita’s latest patents reflect his innovative approach to solving complex problems in data management. The first patent is for an "Apparatus for reproducing data from a regenerative signal using a PLH." This invention utilizes a Phase-Locked Loop (PLL) circuit that produces a synchronous signal by leveraging a regenerative clock signal derived from a recording medium. The system intelligently manages defective portions of the regenerative clock signal by re-reading the same sector from the medium to obtain an accurate regenerative signal. By setting a low loop gain during these defective periods, the invention minimizes synchronous faults in the PLL circuit.

The second patent is an "Information recording and reproducing apparatus for reducing average DC." This technology records information signals that integrate data signals with synchronizing signal patterns at predetermined intervals, employing a specific coding rule to manage signals without a DC free property. By comparing accumulated values from memory and utilizing a pattern inversion circuit, Narita's method effectively manages the polarity of recorded signal patterns, ensuring optimal information fidelity.
