IPC: G11B25/04
Filed: 1985-10-18
Abstract: PURPOSE:To prevent the positioning accuracy of a magnetic head from being affected by temperature changes by tilting the magnetic head in the same direction orthogonal to the head moving direction when a disc rotation shaft and a carriage support shaft reach the tilted state due to a gap caused by the temperature changes. CONSTITUTION:When a temperature rises, a gap is caused between an outer race of a bearing 8b and a bearing housing 7 by the difference of the thermal expansion coefficient between the outer race of the bearing 8b and the bearing housing 7 with respect to the part of a disc rotation shaft 6. With respect to the part of the support shaft 17, a gap is caused between the housing 20 and the inner circumferential face of a hole 21 of a carriage block 19. When the gap is caused in this way, the disc rotation shaft 6 and the support shaft 17 are both tilted in the direction of arrow B while the tilted direction is limited by the action of radial pre-load devices 12, 24 and the disc rotation shaft 6 is rotated without lateral deflection. Thus, the magnetic disc 1 and a head carriage 15 are tilted simultaneously in a direction not given effect on the positioning of the magnetic head 16 to keep the initial positioning accuracy.
