摘要:
A write-erase magnet assembly for a data storage device including: a permanent magnet having a longitudinal axis and having a first longitudinally extending face portion with a first polarity and a second longitudinally extending face portion with a second polarity opposite the first polarity for alternately producing write and erase magnetic bias fields on an adjacently positioned data storage medium; a magnet support assembly for rotatably supporting the permanent magnet; a magnetic detent fixedly positioned relative to the longitudinal axis of the permanent magnet for magnetically producing a biasing torque on the magnet tending to orient the closer of the first and second face portions of the permanent magnet in adjacent relationship with the detent. A coil for applying flipping torque and braking torque for an eddy current rotation dampening assembly are also disclosed.

摘要:
Techniques are described for securing a magnetic head to a support carrier for the head in a magnetic storage device (e.g., a tape drive apparatus or disk drive apparatus). One such technique involves temporarily supporting a magnetic head on a fixture which is adapted to cooperate with openings on the magnetic head to orient the head in a predetermined alignment attitude so that the head may be permanently mounted in the magnetic storage device. In another embodiment the fixture may be part of the magnetic storage device itself. There are also provided various embodiments of magnetic heads having openings for accessing a planar interface between the halves of a magnetic core within the head. By accessing this interface the magnetic head may be aligned in a predetermined alignment attitude.
摘要:
Methods and apparatus may augment the utility of an electrically powered vehicle. A first electric motor (110a or 111a) may be provided with a first effective gear ratio, a second electric motor (110b or 111b) may be provided with a second effective gear ratio, and additional electric motors may be provided additional effective gear ratios. An electrically powered vehicle may be differentially powered by said electric motors at said different effective gear ratios. A transdisciplinary electrical diagnostic processor (440) may process electrically recondite operation parameters of one or more electrical components to provide transdisciplinary diagnostic output to a user. A standardized modular interface (540) supported on a trailer chassis (510) may be configured to accept multipurposed modular interchangeable trailer tops (560) at an interchange position (550) of said trailer chassis (510). A hand actuated accessory mount may be provided with a quick release interface (322).

摘要:
An optical disk cartridge insertion apparatus for an optical disk storage and handling system for use in association with an optical disk cartridge of the type having a rear end portion which is adapted to be inserted into an optical disk reading device and having a forward end portion which is adapted to be grasped by a human operator for handling the cartridge comprising a cartridge receiving assembly for receiving an optical disk cartridge in a predetermined orientation therewith, said cartridge receiving assembly being displaceable between a first relatively rotated operating position and a second relatively rotated operating position angularly displaced from said first operating position.
摘要:
Various embodiments of a magnetic head are described that include access means for accessing a planar interface between the sandwiched halves of a magnetic core within the magnetic head. By accessing this planar interface, the magnetic head may be precisely permanently aligned in a magnetic reading/recording apparatus in a precise, predetermined alignment position.
