Title: Rotary head type magnetic video recording and reproducing device
Inventor: TSURUOKA KEIICHIROU
IPC: G11B15/02
Filed: 1982-05-25
Abstract: PURPOSE:To reproduce an excellent still picture, by detecting which track is scanned automatically by a head at the reproduction of the still picture, and running a tape for a prescribed amount afterward, then stopping the tape. CONSTITUTION:A switching signal (a) is switched again from the STILL to the PLAY side, and an output signal (f) of an FF10 is kept to a high level until a gate 11 is interrupted. When the signal (f) goes to a high level, a gate 7 is interrupted and a capstan motor 5 is driven with only a pulse generated from a pulse generator 14. When the signal (f) goes to the high level, a prescribed time width of pulse is generated from the generator 14, the motor 5 is driven for a prescribed amount via a motor driving circuit 4 and then, the motor 5 is stopped. The amount of pulse from the generator 14 is set so that the tape is run until no noise band exists.

Title: Manufacture of magnetic head slider
Inventor: ITO MASARU
IPC: B23P13/00
Filed: 1990-04-05
Abstract: PURPOSE:To effectively control accuracy for the medium sliding surface of a magnetic head slider by grinding a surface to be the medium sliding surface of a block object in the shape of the head slider and afterwards exerting an etching treatment onto this ground surface by irradiating this surface with gases. CONSTITUTION:The block object is formed by the Mn-Zn polycrystalline ferrite material of an average perticle diameter 5-7mum, for example, in the shape of the head slider. Next, specular finishing is exerted onto a surface corresponding to a magnetic medium as this block object by machining. Afterwards, by using a manufacturing device, the etching treatment is exerted onto the block object on a rotary table by ion irradiation. Therefore, since the accuracy for the medium sliding surface of a magnetic head slider 6 can be controlled by the etching treatment with the ion irradiation, it is not necessary to use a grinding machine in a special shape conventionally required for preventing attraction to a magnetic medium.

Title: Tension servo circuit
Inventor: SATO KAZUO
IPC: G11B15/43
Filed: 1985-04-26
Abstract: PURPOSE:To attain a pure electrical tension servo mechanism by forming a speed detector for generating pulses in accordance with the rotating speed of a reel board, a DC voltage generating part and an electromagnetic brake for approximately fixing tape tension. CONSTITUTION:A saw tooth wave signal SW is changed at its peak value in accordance with winding diameter and a peak signal PKS outputted from a peak holding circuit 104 is inputted to the electromagnetic brake 56. Consequently, the electromagnetic brake 56 applies braking force corresponding to a voltage value applied to the reel board. When the winding diameter is large and the tape tension at a reel feeding outlet is small, the rotating speed of the reel is delayed and the voltage applied to the brake 56 is boosted. When the winding diameter is small and the tape tension at the reel feeding outlet is large, the braking force applied to the reel board is reduced. Namely, the tape suction can be maintained at an approximately fixed value by electromagnetically controlling the braking force applied to the reel board in accordance with the length of the remaining tape.
