Latest Patents

Miyazaki's latest patents include a laser power controller and an optical disk device. The laser power controller is designed to manage the power of a light source directed at an optical medium. This device features a reflected light detector that identifies reflected light from the optical medium when it is irradiated by an optical beam. It also includes an arithmetic unit that calculates the transmissivity of light transmitted from the disk surface to the recording layer. The power control means adjusts the light source's power based on the arithmetic unit's calculations.

The optical disk recording/reproduction apparatus incorporates a detection mechanism for identifying dirt on the optical disk. This apparatus utilizes recording and reproducing means to emit a light beam onto a disc with a wobbling track. It includes reflected light detection means and wobble signal detection means to monitor the wobble amplitude signal. The variation rate detection means identifies dirt on the disc by analyzing the wobble amplitude signal before any information is recorded or reproduced.
