Abstract: A disk drive storage system comprises an array of disk drive units (230). The disk drives (160) contained in the units have a diameter of 65mm and rotate at 10,000 RPM which has the effect of reducing latency. In a preferred embodiment data and corresponding parity information are converted into portions and stored on a respective different one of the disk drive units. Data stored on a filed disk drive unit can be regenerated on a replacement disk drive unit. A disk drive unit can be replaced without powering down the system. Four disk drive units can be arranged in a four drive system to match the space geometry of the traditional half-high flexible disk drive used in a personal computer.

Abstract: METHOD OF TRANSPORTING CARDS IN A PUNCHED CARD READER In a card transport for a punched card reader in which the bottom card in a card hopper is moved sideways before moving forwards into the card reading zone, each card, as it reaches the bottom of the hopper, is moved sideways through a distance less than the width of the card such that the perforations in the card are moved out of registration with the perforations in the card immediately above it, and interlocking of adjacent cards is thus obviated.

Abstract: A processing machine, particularly a reader, for punched document cards including a hopper for a deck of the document cards, pick rolls disposed beneath the hopper in such position as to feed the document cards transversely thereof from the bottom of the hopper, a vertically movable hopper bed for moving the deck onto and off of the pick rolls to make them effective or ineffective, a deck lifter positioned beneath the card deck in the hopper for supporting one side of the card deck after the bottommost card has been moved transversely thereof partially out from underneath the other cards in the deck, driving rolls for moving the bottommost card longitudinally after it has been partially so moved from underneath the rest of the deck and means operative for reading punched holes in the document card on continued longitudinal movement of the card.

Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.
