Abstract: 1477762 Feeding record tapes INTERNATIONAL BUSINESS MACHINES CORP 5 Aug 1975 [17 Dec 1974] 32608/75 Heading G5R [Also in Divisions F2 and B8] A tape cassette 30 (Fig. 6) has a tape 126 moved between reels 122, 124 by engagement of a belt 140 with the tape, the belt 140 being driven by a pulley 136 engaged by a driving roller 64. The driving roller 64 is rotated in forward or reverse by pivoting of an arm 56 (Fig. 1) to engage a roller 62 carrying roller 64 with either of a pair of oppositely-driven driving rollers 52, 54. Brake arms act on roller 62 when it is in neutral (Figs. 4 and 5, not shown). The cassette 30 is received in a slot defined by members 24, 26 which have guiding projections 102, 104 which engage slots 152, 154 of the cassette. Projection 102 also pivots a guard 142 to expose the tape 126 to a read/ write head 86. A set of spring-biased rollers engage slots in the case of the cassette to resiliently hold it against roller 64 (32, 34, Fig. 3, not shown). A phototransistor 94 and light source 96 sense when the tape is nearing an end. Two tape cassettes may be operated by a single drive motor 38 (Fig. 9, not shown).

Abstract: A magnetic disk provided with different digital bytes inside and outside of the center line of a magnetic track on the disk, and transducer and recording mechanism for detecting the passage of the digital bytes across the transducer and recording these bytes as the disk rotates so as to determine the distance the center of the transducer is spaced from the center line of the magnetic track. The recorded digital information is used for stepping a transducer stepping motor a distance corresponding to the stored digital information to move the transducer to have its center in correspondence with the center of the track. In one embodiment, the digital information is stored in a circular reference track adjacent the edge of the disk, and in another embodiment the digital information is stored in spiral tracks extending toward the center of the disk.

Abstract: TAPE CARTRIDGE DRIVE A machine for holding a tape cartridge and including propelling means for driving the tape through the cartridge in both directions. The machine has a cartridge receiving slot with a drive roll at the bottom of the slot disposed on a rotatable drive member carried by a swingable member. A pair of drive rolls are driven from an electric motor and are disposed with respect to the swingable member so that, when the swingable member is swung in opposite directions, the drive rolls drive the rotatable drive member in opposite directions for thereby driving the tape in opposite directions. A pair of swing arms are on opposite sides of and are both effective on the rotatable drive member in a neutral position of the swingable member for braking the drive roll at the bottom of the slot. The swing arms are moved out of braking engagement with the rotatable drive member when the swingable member is moved to bring the rotatable drive member into driven relationship with respect to said pair of drive rolls.

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: A thin flexible magnetic disk rotatably disposed in a cartridge of rigid material and protected thereby. The disk is loosely mounted on a driving hub assembly and has an arrow shaped center hole surrounding a central round hub portion of the hub assembly. A drive pin is carried by the hub assembly and extends loosely through a corresponding hole located in the disk and spaced from the center of the hub assembly and located on a radial line preferably of about 90 degrees with respect to a radial line passing through the apex of the straight hole edges forming the arrow so that the disk is automatically centered on the hub assembly due to any restraint on the disk during its rotation.
