Filed: 1990-01-22
Abstract: PURPOSE:To prevent the damage of an optical disk and an objective lens to improve the reliability by providing a focusing control abnormality detecting circuit consisting of an adding circuit which detects the quantity of reflected light and a comparator circuit which detects the level of the quantity of reflected light. CONSTITUTION:All outputs of detectors in a pickup 3 are applied to a reflected light quantity sum detecting circuit 10 to obtain a reflected light quantity sum signal. The output of this circuit 10 is applied to a comparator 11 and is compared with the output of a reference voltage generating circuit 12. The output of the comparator 11 is applied to a focusing control circuit 5, and a focusing control on/off switch in the focusing control circuit 5 is turned off by a focusing abnormality detection signal 22 of the output of the comparator 11 if the focusing control is abnormal. Thus, possibility of contacting between the optical disk and the objective lens is greatly reduced to prevent flaws of the optical disk and the damage of the objective lens, and the reliability of an optical disk device is improved.
