Title: Production of magnetic head
Inventor: SHIMIZU NOBUO
IPC: G11B5/31
Filed: 1984-01-18
Abstract: PURPOSE:To improve characteristics of a magnetic film formed on a lower insulating film by filling up spaces of a lower conductor coil completely with an insulating film to make the lower insulating film, which is formed on the lower conductor coil, flat. CONSTITUTION:Aluminium 214 is vapor-deposited onto a sapphire substrate 201 and is etched to a prescribed shape to form a lower conductor coil pattern 202, and a resist 203 is peeled. A resist 215 is applied, and the lower conductor coil pattern 202 is used as a mask to perform exposure to light and development from the rear face of the sapphire substrate 201, thereby forming a resist pattern 216 for lift-off of the insulating film filling up spaces of the lower conductor coil. Thus, spaces of the lower conductor coil are filled up completely because of no side etching parts to improve the surface roughness of the insulating film on the lower conductor coil, and pinning for movement of a magnetic wall of the magnetic film formed on this insulating film is prevented to improve the permeability, and thus characteristics of the magnetic film are improved.

Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption by providing a shape memory alloy formed into a strand and exhibiting super-elasticity by current-carrying, a drive body operated by current-carrying, and at least one bias spring connected to the drive body. SOLUTION: A shape memory alloy member 2 is formed into a strand by bending and bundling a wire material in the center, one end thereof is connected to a power source electrode 6, and the other end is connected to an earth electrode 7. A bias spring 4 has one end connected to a support part 9 and the other end connected to a drive body 2 to energize it in direction X2. When a current is carried to the shape memory alloy member 2, it exhibit super electricity to energize the drive body 3 in direction X1 and retains it in a position close to a fixed wall 5. Accordingly, the drive body 3 is moved in the direction X1 or in the opposite direction X2 by limiting the feed of the current. Since the same memory alloy member 2 is formed in the strand shape, the energizing force to the drive body 3 is increased, and the power consumption for the operation of the drive body can be reduced.
