Title: Read error recovery method for multi-track disk reproducing device
Inventor: TAKAHASHI YORIO
IPC: G11B7/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an optimum recovery method which minimizes a decrease in read speed when the multi-track disk reproducing device which can reproduce data of more than one track at the same time has a read error. SOLUTION: A following read means among read means 41, 42, 43, and 44 capable of simultaneous reading is used to reread an error occurrence place and a precedent read means continues to read data out of an unread area. When the improvement of the read speed can be expected even after the error occurrence place is reread, a track jump is made immediately to assign more read means for unread tracks, thereby minimizing a decrease in read speed before and after the error occurrence place is reread.

Title: Head actuator and recording/reproducing device
Inventor: OKADA KANZO
IPC: G11B7/122
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To miniaturize and lighten a head part by installing a head so that it faces a disk-like recording medium, connecting the head part to the air flow- out side of a base part and mounting a mobile object that can move a head slider provided with an electricity/machine conversion element to the radial direction of the disk-like recording medium. SOLUTION: An actuator control part 7 controls a coarse movement VCM driving circuit 5 and a fine movement PZT driving circuit 6 based on target track information given from a disk controller and a position detection signal detected by a position detection circuit and executes tracking servo control. An optical recording/reproducing head installed in the head part of the head slider 21 floats from the surface of a disk by rotation-driving the optical disk 1 at constant speed by a spindle motor 3. Since floating quantity and floating attitude are decided by the structure of the air lubricant faces of the base part and the head part in the slider 21, information can be recorded/reproduced without focus servo control.

Title: Chroma signal limiter
Inventor: SAKINO TOSHIHIKO
IPC: H04N9/85
Filed: 1991-12-25
Abstract: PURPOSE:To set up a chroma signal to a waveform symmetrical in the vertical direction by varying the amplitude limiting value of the chroma signal in accordance with a Y signal. CONSTITUTION:A C-signal source 2 is connected to one of the other both ends of a diode bridge circuit 1 and a load R is connected to the other end as an output terminal and grounded. A Y' signal is inputted from a Y signal source 3 between the base of a transistor(TR) TR1 and ground to the base and the emitter and collector of the TR1 are respectively connected to the bases of TRs TR2, TR3 respectively through resistors R2, R3. When a composite signal is inputted from the C-signal source 2 and the Y' signal is inputted from the Y signal source 3 at the time of setting up resistors R1, R4 and R5, R6 to respective identical values, current I flowing into the circuit 1 is changed by the Y' signal and a recomposed signal from the output 4 can be applied for fixing the peak level of the white side C signal as a composite signal. Consequently an amplitude limiting circuit capable of limiting the amplitude of a chroma signal to amplitude fixing a vertically symmetrical waveform generating no secondary higher harmonic can be attained.

IPC: B03C3/74
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To detect accurately locking of a motor by a method wherein a motor lock detecting level is set high during a time which is slightly shorter than a time required for a cleaning member to transfer between both ends of a wire electrode, and after an elapse of the slightly shorter time, the detecting level is set high. SOLUTION: A propulsion slider 7 screwed on a threaded shaft 6 to be rotated by a motor 5, and a guiding slider 9 sliding along a guide shaft 8 parallel to the threaded shaft 6 are integrated by connecting by a stay 10, and four cleaning members 4 are supported on the stay 4 to constitute a cleaning unit 11. Then, a motor locking detection level by a motor locking detection means is set at a high level only for a time T1 slightly shorter than a time required for the cleaning member 4 to transfer between a home position A and a reversely turning position B. After T1 has elapsed, the motor locking detection level is set at a low level. Thereby false detection of an excess current owing to increase of a load in cleaning operation is reduced, and stable cleaning operation is executed.
