US Patent:

7394651, Jul 1, 2008

Filed:

Dec 21, 2005

Appl. No.:

11/316049

Inventors:

Douglas A. Green - Anaheim Hills CA, US
Scott L. Hanson - Mission Viejo CA, US
Mark R. Thompson - Huntington Beach CA, US

Assignee:

Quantum Corporation - San Jose CA

International Classification:

H05K 5/00

US Classification:

361685, 361679

Abstract:

A computer peripheral device mounting arrangement has a pair of computer peripheral device mounts. Each computer peripheral device mount includes a computer peripheral device side bracket that is mounted on an exterior sidewall of the computer peripheral device. Each computer peripheral device mount also includes a drive bay bracket fixedly positioned in a drive bay. Clips and slots provide a non-locking securement arrangement on the computer peripheral device side bracket and the drive bay bracket. The computer peripheral device side bracket and the drive bay bracket of each computer peripheral device mount is secured by a single screw that prevents relative movement between the computer peripheral device side bracket and the drive bay bracket.

Assignee:

Archive Corporation - Costa Mesa CA

International Classification:

G01B 1114

US Classification:

356358

Abstract:

An optical alignment system for aligning a multiple gap tape head assembly of a tape drive, including a cartridge plate insertable in a tape drive and having a first surface mirror that is parallel to a reference plane for the drive when the plate is inserted in the drive, a microscope objective imaging lens for providing images of the head gaps of the tape head assembly, a video camera and display for providing an operator viewable display of the output of the imaging lens, translation apparatus for moving the imaging lens, and an interferometer cooperating with the first surface mirror for maintaining the imaging lens at a constant distance relative to the first surface mirror as the translation apparatus moves the imaging lens from one head gap to another, such that the imaging lens moves in a plane parallel to the reference plane for the drive. By maintaining the imaging lens at a constant distance relative to the first surface mirror reflecting surface, as the imaging lens is moved from one head gap to another, the misalignment of a tape head assembly can be detected and corrected by an operator by reference to the images of the head gaps which are displayed with a reticle that is at a fixed location in the field of view of the imaging lens.

International Classification:

G11B 5584

US Classification:

360 7802

Abstract:

A voice coil driven positioner is provided for positioning the magnetic head of a tape drive relative to the tape of a removable tape cartridge. The head positioner includes a low-mass carriage that supports the head on one end and the voice coil on an opposed second end. A low friction guide mechanism guides the carriage along a precision movement path that carries the head across tracks of a supplied multi-track tape and simultaneously carries the voice coil through a flux field generated by a stator. A movable portion of a position detector is attached to the carriage and located within the hollow of the voice coil for reciprocating into a hollow passageway of the stator together with reciprocation of the voice coil into another hollow of the stator. A fixed portion of the position detector is attached to the stator and located compactly within the hollow passageway of the stator. A programmable lookup table converts measurement signals output by the position detector into pre-calibrated, head-position indicating signals.

International Classification:

G11B 2112

US Classification:

360 75

Abstract:

Disclosed is a method and apparatus for guidance of a magnetic head to a predetermined reference position generally used to recalibrate head to media orientation. An electro-magnetic or photosensitive device is provided to accurately and repeatably position a magnetic head carriage to a reference point in order to calibrate the head gap location with respect to parallel tracks across the width of the media. A coarse and fine adjustment method is used to improve the accuracy of establishing the head at the reference position.
