    摘要： A drive-implemented method according to one embodiment includes guiding a magnetic medium over a magnetic head at an angle at which the magnetic medium flies over a leading outer portion of the head, engages a leading edge of a tape bearing surface of a central portion of the head, and engages an inner edge of a tape bearing surface of a trailing outer portion of the head. The inner edge of the tape bearing surface of the trailing outer portions skives air from the magnetic medium when the magnetic medium travels in a direction from the central portion towards the trailing outer portion.

    摘要： A first data group in an access sequence is selected. Those data groups located in specified regions of the tape medium are separated from other data groups located in alternative specified regions of the tape medium. The distance from the current position of the tape medium is set to be a logical distance value, determined by a calculation function, that is substituted for the physical distance value for the data groups that are located in the specified regions as compared with other data groups located in the alternative specified regions. A second data group in the access sequence is selected. The logical distance value is then determined by multiplying a coefficient based on a physical positioning of each of the data groups in the tape medium, and a percentage of those of the plurality of data groups that have already been selected as the first data group and the second data group.

    摘要： A hard disk drive enters a low power mode to reduce power consumption. To maintain communication with a host device, a communication interface remains energized along with a circuit portion storing configuration data for the communication interface. To energize the communication interface and the circuit portion, low power voltage regulators provide suitable reference voltages. One low power voltage regulator is dedicated to this purpose. Another voltage regulator is converted from an active, switching mode to a low power, linear mode to provide the necessary reference voltage. Also, unique handshaking signals are used to control entry and exit from the low power mode by the hard disk drive.

    摘要： A metallic plate that is a structure of a release member, the release member being configured to be integrally rotatable with a reel accommodated in a case, and the release member moving a locking member from a locking position, at which the locking member locks rotation of the reel relative to the case, to an allowing position, at which the locking member allows rotation of the reel. The metallic plate comprises a touching surface that is to be touched by a distal end of a sliding protrusion portion that protrudes from the locking member; and a structure such that, if a plurality of the metallic plate are stacked in a plate thickness direction in a state in which the metallic plates are not attached to release members, the touching surface of each metallic plate is not in contact with any other of the metallic plates.

In one aspect, a system includes a head for performing read and/or write operations, a first set of motors for performing positioning operations on a first tape, a second set of motors for performing positioning operations on a second tape, and a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the first set of motors to pass the first tape over the head while causing the second set of motors to perform at least one of a coarse locate and a rewind operation on the second tape. Additional systems and methods are also disclosed.

    摘要： A power control device comprising an always-on-domain (AOD) which includes control logic circuitry for controlling power from a power source, load switches, bias current generators. The power control device also includes, outside of the AOD, functional blocks. The control logic circuitry is configured to receive a signal to go into a lower power state, initiate a shut-down sequence of the load switches and the bias current generators of the AOD, to disable circuitry outside of the AOD, including the functional blocks of the power control device and loads controlled by the power control device, and operate in a low power state to detect a wake-up signal. The shut-down sequence may additionally include sequencing off voltage regulators outside of the AOD and a clock control inside the AOD.
