Abstract: PURPOSE: To prevent the loss of data even when one driven is out of order by storing data in a first to a (n-1)th drives and parity information in an nth drive. CONSTITUTION: A disk storage system includes an array/cluster controller 5 and plural storage mechanism arrays 7-9. The constitution of four (n=4) separated disk files 7a-7d into which the respective arrays are divided is preferable since a half/high disk drive is geometrically matched with an existing shape factor of a personal computer. The array is designed as the subsystem of a direct access storage device, is a system so that the data are stored and fetched at high speed and with high reliability and the data are dispersed between the constituent elements of the system.

Abstract: PURPOSE: To prevent stress and strain by installing a file cover which includes a buffer fitting means. CONSTITUTION: Plural disk stacks 15 are fitted to a spindle assembly 44 to allow their simultaneous rotation. Each magnetic transducer is adapted to its related disk data face so as to allow its transfer from one track position to another one and, supported by the actuator, the horizontal and vertical impact loads are controlled by a buffer fitting means. The disk 16 and the actuator are enclosed by cover parts 72, 73. Thus by covering the head disk assembly, introduction of stresses and strains are suppressed and writing and reading without errors are possible.
