A speaker 7 as an additive sound source is installed in the flow passage 22. The output of the microphone 4 in the flow passage 21 is amplified and digitized to a reference signal X, which is convolution integrated together with an adaptive filter coefft. W and is made into an input signal (y) of the additive speaker 6. On the other hand, the reference signal X1 of the flow passage 22 is obtd. by convolution integration of the reference signal X and the filter coefft. G of a correction filter 19. The input signal y1 of the speaker 7 in the flow passage 22 is determined by convolution integration of the signal X1 and the coefft. W of the adaptive filter 20.

Title: Moving controller for optical head
Inventor: KARAKIDA SHIYOUJI
IPC: G11B7/09
Filed: 1989-01-18
Abstract: PURPOSE:To discriminate an area where a track exists and an area where no track exists without using an external sensor by monitoring an output pulse of a window comparator for each prescribed time. CONSTITUTION:A rack error signal obtained from a signal processing circuit 104 has a large amplitude in an area where a track exists and a small amplitude in an area where no track exists. Thus, when a comparator 105 compares a track error signal with a proper window level, a consecutive pulse appears in an area where a track exists and no signal appears in an area where no track exists excepting that one-shot pulse due to noise or flaw of a disk. A position discrimination means 107 discriminates an area where there is any track or not by counting pulses inputted in a unit time. Thus, it is discriminated an area where a track exists and an area where no track exists without using an external sensor.
