Title: Optical disk recording and reproducing device and optical disk
Inventor: AKAHORI HIROSHI
IPC: G11B7/09
Filed: 1988-06-24
Abstract: PURPOSE:To attain stability for temperature change or the inclination of a disk, etc., by constituting a device in such a way that the quantities of crosstalk from adjacent two oblique planes are detected by an optical detector which receives almost the semi-circular area of reflected light in a direction of oblique plane, and the quantities of crosstalk obtained from two oblique planes can be set equally. CONSTITUTION:In the case of performing tracking in a direction of arrow head along a plane B by a light beam on the oblique plane, the detection of the quantities of crosstalk from a plane A and a plane C can be performed by quadruple optical detectors 1a and 1b. A peak hold circuit 2a holds the peak value of a crosstalk signal from the plane C, and a peak hold circuit 2b holds the peak value from the plane A, respectively, then, the quantities of crosstalk 7 and 8 can be obtained. Here, it can be recognized that track deviation to the plane A side is generated when a differential signal 9 for track deviation between the quantity 7 of crosstalk from the plane C and the quantity 8 of crosstalk from the plane A shows a positive value, and it is generated to the plane C side when it shows a negative value, and correction to set the differential signal at '0' is applied in respective case. In such a way, it is possible to obtain a stable recording and reproducing characteristic even when the track deviation due to the temperature change or the inclination of the disk is generated.

Title: Closed loop control circuit for magnetic disc device
Inventor: KONO KEIICHI
IPC: G11B5/596
Filed: 1984-07-30
Abstract: PURPOSE:To decrease the settling time by increasing automatically the gain of a closed loop control circuit at fine control when a position displacement is larger than a prescribed value at fine control switching. CONSTITUTION:Two sets of series circuits comprising series connection of a diode and a resistor are connected in parallel across a resistor R1 in a position feedback gain circuit A'X so that the diodes are poled oppositely. Since the diodes D1, D2 are connected in anti-paralell, the gain when an input voltage VIN from a filter is positive is R2/R1+R4 and the gain when the VIN is negative is R2/R1+R3. In this case, junction type silicon diodes conducting at a prescribed forward voltage or over are used for the diodes D1 and D2 and the leading voltage 0.6-0.7V is utilized. When the displacement is larger than a prescribed value at fine control switching, the settling time is decreased by the increased gain. Vout is an output of the A'X.
