Magnetic disk apparatus having at least six magnetic disks

摘要

A magnetic disk apparatus has a base member and a cover mounted on the base member to form an enclosure having at least six magnetic disks rotatably supported therein. First and second transducers are included for writing information on and reading information from upper and lower surfaces of adjacent ones of the magnetic disks. The transducers are supported by leaf springs in close proximity to both surfaces of adjacent ones of the magnetic disks. The leaf springs extend in a radial direction with respect to the magnetic disks and are supported on one end by a plurality of head arms. The leaf springs are arranged substantially within the same plane parallel to the magnetic disks so they do not overlie one another. A voice coil motor is provided for moving the head arms in order to position the transducer pairs in predetermined positions. A circuit board is included for controlling the magnetic disk apparatus.
