Title: Optical disk drive
Inventor: MASHITA TSUGUAKI
IPC: G11B7/09
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To adjust the focusing servo by detecting the amount of jitter in an optical disk drive. SOLUTION: The reflected light from an optical disk 10 is converted into RF signals in the optical pickup 12, amplified in an RF amplifier 14, and supplied to an equalizer 16.
