<p>A magnetic disk unit of form factor size with a low power consumption, a short average seek time and a high performance. The unit includes at least two spindles (3', 4') for supporting and rotating magnetic disks. Specifically, two 1.3-inch disks (3, 4), three 1.0-inch disks (5, 6, 7) or four 0.7-inch disks (8, 9, 10, 11) are arranged in a housing (1) originally intended for a 1.8-inch magnetic disk. The unit further includes a device for writing and reading information while selecting a spindle. The card-type disk unit thus can be reduced in thickness, with a smaller power consumption for starting the disk rotation and further with an improved average seek velocity. <IMAGE></p> |
