Title: Optical recording and reproducing device
Inventor: YOSHIDA TOMIO
IPC: G11B7/135
Filed: 1984-06-28
Abstract: PURPOSE:To rewrite a signal in an optical section detected with a playback light spot by setting the 1st light spot for reproduction, the 2nd elliptic light spot for erasure, and the 3rd recording light spot for recording nearby on the same guide groove an optical recording disk so that an optional point on the optical recording medium is scanned in order. CONSTITUTION:A semiconductor laser 11 is a light source for reproduction and its output light has wavelength lambda1 and is converged through a condenser lens 12 and stopped down by a stop-down lens 16 to form a circular fine light spot on the optical disk 18. A semiconductor laser 29 is a light source for erasing a recorded signal and its output light has wavelength lambda2 and is reflected by a light beam multiplexer 13 toward the disk 18, thereby forming the elliptic light spot L2 along the groove 2 on the optical disk 18. Similarly, a semiconductor laser 32 is a light source for recording a signal and its output light has the same wavelength lambda2 with the semiconductor laser 29 or reproduction and forms a light spot L3 on the groove 2 on the optical disk 1 closely to the 2nd light spot.

Title: Ultrasonic wave delay circuit
Inventor: AKIMOTO MASAO
IPC: H03H9/30
Filed: 1984-06-28
Abstract: PURPOSE:To obtain a signal superimposed on an input terminal voltage of an ultrasonic wave delay line, reflected at an output terminal and delayed by double by subtracting a voltage corresponding to an input signal voltage from a voltage at the input terminal voltage of the ultrasonic wave delay line. CONSTITUTION:A signal voltage E1 at input terminals 16, 16' is a superimposed voltage of a signal voltage delayed by a time twice the one-way delay time of a delay line 8 and a voltage E0 at a signal input terminal, because the E1 is reflected at an output terminal of the ultrasonic wave delay line 8 and returned again. A signal voltage multiplying the voltage E0 at the input terminal by alpha is subtracted from a signal voltage multiplying the signal voltage E1 by beta at a subtractor 12. The term of the input signal voltage is eliminated from the superimposed voltage and only the reflected wave signal voltage is extracted by selecting the value alpha as alpha=betaXZi/(Z+Zi), where Zi is an input impedance of the ultrasonic wave delay line and Z is an impedace 9.

Title: Reproduction of substrate for hard disk
Inventor: NAKAMURA ZENKICHI
IPC: B29B17/02
Filed: 1988-06-02
Abstract: PURPOSE:To reduce reproducing and processing time of hard disk substrates and to increase the yield of reproducts by plasma ashing the substrate and then polishing to remove a carbon film and magnetic layer on the substrate. CONSTITUTION:The hard disk consists of the substrate 1, Ni-P plating or anodized aluminum layer 2, the magnetic layer 3, carbon film 4 and lubricating layer 5 formed successively. The film 4 is subjected to plasma ashing. The carbon constituting the film is oxidated into oxide and hydrogen constituting the layer 5 changes into H2O to escape from the surface. By polishing the exposed layer 3, it can by removed easily with small heat because no carbon film is present, while the plating layer 2 remains without changing into ferromagnetic state and is free from wide flaws. Thereby, processing time of reproduction polishing is reduced and the productivity and yield of reproducts is improved.

Title: Endless tape cassette
Inventor: HASHIMOTO KAZUO
IPC: G11B23/06
Filed: 1982-08-03
Abstract: PURPOSE:To rewind an endless tape, by providing a tape take-up part which can turn in both directions, and a device which gives tension to the endless tape. CONSTITUTION:A tape feed contact part 3 is set at a tape feed part of the main body of a cassette, and a tape 8 is shifted toward the arrow (a) by the function of the tape feed part. A tape take-up part 1 connected to a tape take-up driving source of the main body is turned opposite to the feed direction of the tape feed part with friction to the tape 8. Therefore, the appropriate tension is generated at a transducer part 4a owing to the conveying force of the tape feed part and the frictional force acting on the direction opposite to the feed direction caused by the revolution of the part 1. Thus the tape 8 is brought into close contact with the part 4a and works with no bend. The operation of the tape feed part is discontinued with a rapid traverse mechanism, and only the function of the part 1 is performed. Then the tension is applied to the tape 8 by a tension applying device. Thus the tape 8 can be rewound by the frictional force produced by the revolution of the part 1.

Filed: 1988-06-03
Abstract: PURPOSE:To detect a position of a pickup, irrespective of reading disk data and to promote reliability on data and also to prevent malfunction by obtaining a moving amt. of the pickup from an pulse duration and period to be generated in accordance with the number of revolutions of a disk. CONSTITUTION:An FG pattern 2 is fitted to the disk of a disk table 1, and by an FG sensor 3 for detecting this black-and-white pattern, the time to be taken by the pattern 2 to pass the sensor 3 is generated as the pulse duration. When the number of revolutions becomes larger, the pulse duration will be decreased. The FG pattern 2 is of a fixed number of stripes around, and the number of revolutions is found by this pulse duration. The time from the previous interruption is calculated by a CPU (microcomputer) 4 to evaluate the pulse duration, and the number of revolutions based on the pulse duration is converted into the moving amt. to be stored in a work area in a RAM. By this processing, at the time of moving the pickup, its moving amt. is sent to a pickup control circuit 5 to move the pickup 6 by the CPU 4.
