Title: Manufacture of magnetic head
Inventor: MUKAIDE NORIAKI
IPC: G11B5/60
Filed: 1989-11-29
Abstract: PURPOSE:To enable high-density recording without damaging a recording medium by forming the slide surface of the recording medium in a dual-sphere shape, positioning a magnetic gap at a peak, and forming an air vent groove at a position recessed from the peak. CONSTITUTION:When the flank lower sides of both slides 2 and 3 where both upper flanks of a magnetic core 1 are sandwiched and fixed are pressed inwardly, the slide surface 4 curves projecting at the part of the air vent groove 9 on a center line and this slide surface 4 is polished in a single-sphere shape, so that the center part of the slide surface 4 becomes a peak. When the sliders 2 and 3 are released from being pressed, the part of the projecting air vent groove 9 sinks to the position recessed from the peak of the slide surface 4 since the slide surface 4 is polished in the single-sphere shape. Then the slide surface 4 is formed in the dual-sphere shape wherein the magnetic gap 7 and the slide surface of the slider corresponding to the magnetic gap are formed as peaks. Consequently, high recording density is obtained and the recording medium is not damaged.

Filed: 1986-12-25
Abstract: PURPOSE:To obtain a position detecting device, which can detect the position of light that is projected on an arbitrary point on an amorphous semiconductor layer, by depositing conductor layers on both surfaces of the amorphous semiconductor layer, which generate electric power by the projection of the light, and providing output terminals, which divide currents flowing through the conductor layers in the X and Y directions and guide out the currents. CONSTITUTION:First and second conductor layers 2 and 4 are deposited on both surfaces of amorphous semiconductor layers 3 having P-I-P junctions, which generate electric power by the projection of light. First and second output terminals 21 and 22 are provided at both end parts of the conductor layer 2 so as to divide a current flowing through the first conductor layer 2 in the X direction and to guide out the current. Third and fourth output terminals 41 and 42 are provided at both end parts of the conductor layer 4 so as to divide a current flowing through the second conductor layer 4 and to guide out the current. Solder layers are formed on the first-fourth output terminals 21, 22, 41 and 42. A rear-surface protecting layer is provided on the second conductor layer 2 other than the parts of the solder layers. For example, the light is projected on an arbitray point by a light emitting and inputting means 5. The arbitrary point is detected based on the current values outputted from the output terminals based on the projected light.
