摘要： A dispensing apparatus and method are disclosed for dispensing sheet material from at least one roll of the sheet material. Dispensing is transferred from a stub roll to a reserve roll automatically in response to sensing a predetermined quantity of the stub roll. An isolating element is provided to lift the reserve roll out of contact with dispensing rollers during dispensing of sheet material from the stub roll, and a nipping element is provided to nip sheet material of the reserve roll when dispensing is transferred from the stub roll to the reserve roll. A cam controls movement of both the isolating element and the nipping element. Structure is also provided for sensing the diameter of the reserve roll of sheet material and providing an indication when the reserve roll is a predetermined diameter. The dispenser is quiet and capacity efficient.

摘要： A disk drive or direct access storage device (DASD) of the type having multiple disks and multiple actuator arms, both the disks and the actuator arms assembled in a stacked manner, advantageously assembled with the locating surface or flange of the actuator disposed on the opposite side of the stacked actuator arms from the side of the disk stack having the locating surface or flange for the disk hub. This opposite flange design results in a substantial reduction in the effects of tolerance buildup and therefore permits the design of the disk drive equal in all other respects to a conventional same side flange arrangement, but permitting additional disks, lower height, less tightly defined tolerances on components or the use of cheaper manufacturing techniques and technologies for recording data.

摘要： A magnetic tape has three evenly spaced-apart longitudinally-extending servo track areas. Four equal-sized longitudinally-extending data track areas are disposed between said servo track areas and between longitudinal edges of the tape and one of said longitudinally-extending data track areas. For track following, all servo track areas are simultaneously sensed for producing one head positioning signal. Data tracks are arranged into four groups of tracks, one-half of the data tracks in each group are concurrently accessed. The data tracks on the tape are arranged in clusters. Each cluster has one track from each of the groups of tracks. Two laterally-adjacent track clusters constitute four data track wraps for serpentine scanning of data tracks. The concurrent track accessing respectively occurs in first and second halves of a data track wrap (there is a number of wraps equal to one half the number of track clusters). Each servo area indicates two lateral positions of the tape to the head. The lateral spacing between the lateral positions is equal to about a data track width. This arrangement makes the servo areas field writable. The magnetic head has a number of data write and read gaps equal to the number of clusters. A set of four servo gaps are interposed between four groups of write and read gaps and positioned to simultaneously sense all three servo track areas.

摘要： A tape reel brake which is mounted in a well in the top of a tape reel hub. The well is inside the tape bearing surface of the hub. The brake is mounted to be compliantly biased away from the base of the well. The hub is seated against a first inside surface of a tape cartridge housing. The hub and brake are seated in the tape cartridge such that teeth on the periphery of the brake are biased against the opposite inside surface of the cartridge housing about the periphery of an opening therein. The biasing of the brake against the opposite inside surface both prevents the rotation of the reel and shields out dust when the tape cartridge is removed from a tape drive. To rotate the reel, a tape drive clutch enters the opening in the opposite inside surface and depresses the brake into the well to mate with a smaller diameter portion of the hub or a recessed portion of the brake. The hub is always maintained on the inside surface of the housing, thereby eliminating lateral motion which could disrupt the tape path.

摘要： A tape path having an implicit squeeze bearing. In such a tape path, one end of the tape is wound upon a first reel, the tape extends around one or more guides, briefly comes into close proximity with itself at the outer wrap of the tape wound upon the first reel, and is wound upon a second reel. By coming within close proximity with itself, the tape forms an implicit squeeze bearing which damps tape tension variation, inhibits the transmission of vibrations from one reel to the other, and eliminates the entrapment of entrained air without any additional rollers or other components. The tape path is suitable for use in a peripheral storage device, such as a magnetic tape drive, and is compatible with a variety of tape cartridge configurations.

摘要： Magnetic storage tape and techniques for erasing and writing to magnetic storage tape having a perpendicular squareness greater than 50 percent and a longitudinal squareness less than 50 percent are described. In general, the magnetic tape may be biased with a remanence magnetization, or magnetic orientation, in any direction. One or two head systems may use various magnetic field patterns to create the desired remanence magnetization. Servo marks may have a remanence magnetization in an opposite magnetic orientation than that of the remaining bias on the servo track, e.g., substantially perpendicular to the magnetic tape. In some examples, a write head may alternate the direction of the magnetic field to continuously bias and write servo patterns to the magnetic tape. In addition, a symmetrical servo mark may be created in the magnetic tape with a write head having a gap width approximately equal to the length of the servo mark.

摘要： The invention is directed to techniques for erasing data storage tape for reuse. In an embodiment, an erase head module for erasing data storage tape comprises a set of erase gaps and one or more servo read elements. The set of erase gaps is configured to coincide with data bands of the data storage tape to allow erasure of only the data bands of the data storage tape while not erasing servo bands of the data storage tape. The one or more servo read elements detect one of the servo bands of the data storage tape when the set of erase gaps are proximate the data bands of the data storage tape to allow the erase head module to accurately track the data bands with the set of erase gaps.
