Abstract
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 for supporting and rotating magnetic disks. Specifically, two 1.3-inch disks, three 1.0-inch disks or four 0.7-inch disks are arranged in a housing 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.
