Latest Patents

Yamazaki holds a patent for an optical disk, disk substrate, and drive. This patent describes an optical disk equipped with a hub at the central portion of a substrate. The invention satisfies a relationship where Y/X ≥ 0.015, preferably Y/X ≥ 0.05, with X representing the projected area of the substrate and Y denoting the contact area between the hub and the substrate. This design prevents slippage between the hub and the substrate, even at higher rotational speeds than conventional disks. As a result, the data transfer rate is improved, and irregular rotation and camming are suppressed, thereby reducing tracking errors and write/read errors.
