Abstract
A disk holding mechanism for use in a disk apparatus includes a disk holder unit (60) for holding a disk (40) inserted into the disk apparatus. The disk holder unit includes a leaf spring (63) which serves as an urging member for urging a substantial center of the disk downwardly from an upper surface of the disk with the disk held in the disk holder unit. The urging member prevents the disk from vibrating within the disk holder unit and restricts vertical movement of the disk itself even if the disk apparatus is subjected to external shake or shock. Thus, it is possible to constantly maintain stable head touch of a magnetic head to a magnetic disk medium (41) of the disk.
