Title: Disk device
Inventor: MATSUNAMI HIROSHI
IPC: G11B7/004
Filed: 2000-05-12
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for playback starting of a disk device sharing a CD and DVD. SOLUTION: An optical pickup 2 is provided with a first laser source 45 for CD and a second laser source 46 for DVD to generate laser beams of short wavelength and large output.
