Title: Innovations of Yukari Hiratsuka
Introduction
Yukari Hiratsuka is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of optical disk technology. With a total of 7 patents, her work has advanced the capabilities of data recording and reproduction.
Latest Patents
Hiratsuka's latest patents include a state detecting device and an optical disk device. The state detecting device is designed for recording data on and reproducing data from an optical disk with a single spiral land/groove configuration. It features a header detector that identifies header regions on the optical disk. Additionally, a PID error detector assesses the accuracy of the address information read from these regions using error detection codes. The device also includes an error count comparator that compares the number of errors per sector with a predetermined value. This allows a state judging circuit to identify the operational state of the optical disk device, enabling controlled recording and reproduction based on the identified state.
The optical disk device patent focuses on a disk-rotation control apparatus. This apparatus ensures that if a signal is not detected normally by a pre-pit-region detection circuit, an error signal is generated to control the disk's rotation. It also manages the rotation based on the detection of synchronizing signals at predetermined intervals, ensuring optimal performance.
