IPC: G11B5/58
Filed: 1982-01-11
Abstract: PURPOSE:To always keep the distance between a magnetic head and a magnetic disk at a prope fixed level in opposing each other, by combining a photoelectric conversion element with a bimorph element. CONSTITUTION:A magnetic head 2 is buried into a holder 3 in opposition to the surface of a magnetic disk 1, and at the same time a light emitting element 4 and a photoelectric converting element 6 are buried into the holder 3. When the distance l is set at a proper level between the disk 1 and the head 2, the light of the element 4 is reflected at a reflecting point (a) of the disk 1 and then made incident to a converting element 5. A bimorph element 6 containing electrodes 6' and 6'' for application of voltage connects the holder 3 and a holding substrate 7. Then the voltage based on the level of the output of the element 6 is applied to the element 6 to control the position of the head 2. As a result, the distance l can always be kept at a proper level.
