PURPOSE:To decrease the vibration due to the resilience of a moving head produced when the moving head contacts and collides with a disc, by moving a moving head block up and down in response to a pressure delivered via the disc with the shift of the 1st head. CONSTITUTION:The moving head block 21 is pressed to a fixed stand 22 at all times with a force of a spring 23 when the moving head 2 is parted from the disc 1. The fixed head 3 and the disc 1 are contacted together. In writing and reading out information, the moving head 2 moves downward and contacts the disc 1. The disc 1 and the moving head block 21 in contact with the lower side of the head 1 are pushed downward with the momentum when the moving head 2 contacts the disc 1 and collides with it, and the resilience of the moving head 2 is absorbed with the downward movement of the moving head block 21 (movement under the holding with a spring 23). |
