Title: Optical recording medium recording and reproducing device
Inventor: WACHI SHIGEAKI
IPC: G11B11/10
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To prevent the reliability from being degraded due to vibration by re-starting a servo for small relative action when an optical head is coarsely moved relatively to an optical recording medium for seeking action and when a small relative servo action becomes inactive and complete. SOLUTION: When it is decided to coarsely move with a linear motor, the optical disk recording and reproducing device 1 ceases servo action for small movement on both sides, and controls the linear motor to move only an upper optical pickup 3 by the number of relative tracks. This generates vibrations. The vibrations are transmitted to a lower optical pickup 4 via a supporting frame 6, and badly shake the optical pickup in the radial direction of an optical disk 2. Then, the optical pickup 4 does not follow a track which was being tracked. This prevents the small moving servo action from deviating from its pull-in range.
