Title: Magnetic disk device
Inventor: TAKAHASHI MINORU
IPC: G11B21/16
Filed: 1983-05-26
Abstract: PURPOSE:To decrease the number of access arms to reduce the mobile mass as well as to reduce the space of the distribution surface among magnetic disks, by holding a pair of magnetic heads at the tip part of the access arm as if these heads held the magnetic disks. CONSTITUTION:Three access arms 23a-23c are linearly distributed opposite to the side faces of magnetic disks 2a-2c respectively. A pair of downward and upward magnetic head mechanism parts 24a and 24b are held at the tip parts of said access arms as if they hold the disks 2a-2c. In such a constitution, the arms 23a-23c never go into the spaces of distribution surface among disks 2a- 2c respectively. The distribution space width of magnetic disks is reduced by an amount equivalent to the thickness of the access arm. This decreases the number of access arms and reduces the mobile mass of the actuator mobile part. Thus a miniature and light-weight structure is possible for a magnetic disk device with a high-speed access.

Abstract: PURPOSE:To prevent disconnection of barrier metal and direct contact between Au or Al electrode with an Si substrate in a semiconductor device by perforating a PSG film on an SiO2 film, superimposing an SiO2 film thereon, and perforating smaller openings thereat to mount electrodes therethrough. CONSTITUTION:A transistor structure of planar type in which an SiO2 film 2a is coated entirely on the main surface of an N-type Si substrate 1 is formed, and an SiO2 film 2c is superimposed through a PSG film 2b. A resist mask 7 is coated, and is etched to form emitter opening 6 thereat, and a sufficiently thick SiO2 film 2a is retained for a base opening 5. Since the etching time of this case is short, an overhang is extremely small. Then, the mask 7 is removed, an SiO2 film 2d is coated thereon, a resist mask 7a is newly used, an opening having smaller size than the initial opening is perforated thereat, and SiO2 films 2d and 2a are completely etched. Since no PSG is formed thereat, no overhang is produced thereat. Subsequently, the mask 7a is removed, a platinum silicide 8, a barrier metal 9, and a gold 10 are attached as electrodes in the conventional manner, and a glass 11 is coated thereon. This configuration does not produce an overhang at the stop of the SiO2 film, and disconnection of barrier metal and reaction of Au-Si or the like are not generated.

Abstract: PURPOSE: To realize the load reduction for the driving device through big reduction of the steering frequency by producing the steering pulse of the other side by the amount equivalent to the integration quantity of one side, if any, to give turn to the other side and at the same time subtracting the pulse number of the other side from the value of integration.  
     CONSTITUTION: When going into the right-drift region, the right-drift signal detected the right-drift going is generated from position detector 1. Thus the right steering pulse is generated from steering pulse generator 3 to secure a right turn like a circular arc. At this moment, the contents of steering pulse integrator 4 is reset to 0 to integrate 1/2 of right steering pulse number n. After this, when going into the neutral point and if the integration quantity of the right steering pulse exists in the contents of integrator 4, and left steering pulse is generated by the amount equivalent to the amount of the right steering pulse to have the left turn. At the same time, the number of the left steering pulse is subtracted from the integration quantity. When going into the left-drift region, the procedure opposite to the right-drift going. Thus nearly a parallel running to the target running lane becomes possible. As a result, the steering frequency can be reduced greatly to lessen the load of the driving device.
