Title: Optical disk device
Inventor: MITANI SHOJI
IPC: G11B7/085
Filed: 1989-05-22
Abstract: PURPOSE:To prevent the deterioration of a recording/reproducing characteristic by providing a reflected light detecting head of an optical disk, a tracking control part, a positioner for placing the head thereon, a positioner position control part, and a positioner processing control circuit, and holding the center of a lens right under an object track. CONSTITUTION:When a positioner processing control circuit 23 outputs a control instruction signal (i) to a selecting circuit 24, an output (e) of a filter 21 is inputted to a positioner power amplifier 22 and a rough position control is executed. Subsequently, by a tracking control circuit, a laser beam is brought to position control onto a target track. Next, a current signal (f) flowing to a tracking actuator from a tracking power amplifier 17 is obtained. The signal (f) passes through a two-stage servo error signal generator 25 and generates a two-stage servo error signal (g). The signal (g) passes through a filter 26 and generates a signal (h). The control circuit 23 generates a positioner two- stage servo position control instruction (h) to the selecting circuit 24 by the signal (i). By this two-stage servo position control, the center of a lens always comes right under an object track, and the compressibility of the whole becomes high.
