Title: Controller for focal point position of optical disk
Inventor: TAKAHASHI SATORU
IPC: G11B7/085
Filed: 1986-11-10
Abstract: PURPOSE:To enable control to be switched to focal point position control even when out of focal point is generated, and no focal point position control functions any more, by immediately and exactly detecting the out of focal point, and continuing a pull-in operation by the output of a pull-in circuit until the focus point of a focal point can be obtained. CONSTITUTION:When the focal point position is remarkably displaced from the plane of an optical disk 21 by disturbance, an out of focal point detection circuit 3 functions, and outputs a detecting signal G, then, switches a switching circuit 6 to a broken line displaying position. Therefore, a pull-in signal D is sent again to a driving circuit 7, and makes the focal point approach to the surface of the optical disk, and by repeating the above operation, the adjustment of the focal point position is performed. The detection circuit 3, after a prescribed reference of disturbance signal being added on a control system, negates the influence of the disturbance signal as the control system when the focal point position control is in an operating state, but, in a state of out of focal point, no control as the control system is performed, therefore, the influence of the disturbance signal appears as it is. In such way, it is possible to detect the out of focal point accurately when the disturbance is generated, and to perform the focal point position control appropriately based on a detected result.
