Title: Optical disk device
Inventor: KONNO HISASHI
IPC: G11B7/095
Filed: 1990-11-14
Abstract: PURPOSE:To enable an accurate tracking error to be detected even if a track offset signal is included in a tracking error original signal by providing a calculation means for generating a tracking error signal by subtracting a compensation value from the tracking error original signal. CONSTITUTION:An output signal of light-receiving regions A and B of a light- receiving element 7 is subtracted by a subtractor 26 and is output as a tracking error original signal TE0. A subtractor 47 as a calculation means subtracts a compensation value DELTAX which is read out of a memory 54 from this tracking error original signal TE0 for obtaining a tracking error signal TE1 and it is output to a drive control circuit 60. Therefore, a track offset due to the movement of a spot on the light-receiving element 7 when a light flux is inclined to a disk can be subtracted from the tracking error original signal, thus enabling the tracking error signal to be detected accurately even if the optical disk and the light flux are inclined to each other.

Filed: 1987-12-08
Abstract: PURPOSE:To stably and correctly scan a rotating magnetic head on a recording track by moving a tracking guide post to a prescribed position while the rotating magnetic head does not scan on the magnetic tape. CONSTITUTION:At the time of reproduction, an average tracking is obtained by controlling the rotation phase of a capstan 9 with the low pass frequency component of the output signal of a tracking error detecting means 13. By the output signal high pass frequency component of the tracking error signal detecting means 13, a post actuator is driven, the position of a tracking guide post P7 is controlled, the position of the lengthwise direction of a magnetic tape 3 at a rotating drum part is made variable, and thus, rotating magnetic heads 5a and 5b are correctly scanned on the recording track recorded on the magnetic tape 3. Further, a tracking guide post P7 is corrected so that the rotating magnetic heads 5a and 5b can be at a next tracking initial position while tracking is not necessary. Thus, the rotating magnetic heads 5a and 5b can be scanned always stably while they are tracked on a recording track.
