Abstract

The invention provides a high-capacity, high-speed data storage device which is extremely compact, rugged and economical. In a preferred embodiment, the data storage device comprises a housing defining a sealed enclosure, a motor mounted within the housing having a rotatable spindle, a flexible disk non-removably mounted to the spindle, and a read-write head disposed within the housing over a first surface of the disk for reading or writing data thereon. By the use of a flexible disk of a material such as Mylar, the housing has an extremely small height, preferably less than 5.0 mm, and the device is economical and rugged. At the same time, high storage capacity and speed is attained by the use of a flying head which reads or records data without contacting the disk. In preferred embodiments, multiple disks and/or multiple heads may be employed for extremely large data storage capacities in ultra-compact devices.
