Latest Patents

Hattori holds a patent for an optical recording/reproducing apparatus. The primary objective of this invention is to enhance medium usability through a laser power adjusting process while maintaining compatibility with read-only type media. The apparatus adjusts laser power using a PCA until it is fully utilized. Once the PCA is exhausted, an additional area is reserved at the outermost circumference position. When this additional area is also used up, a new additional area is reserved at the inner circumference side of the previously used area to continue adjusting laser power. This design ensures that format compatibility with read-only optical discs is preserved, while also allowing for effective laser power adjustments.
