Cartridge Loading Apparatus And Methods Of Manufacturing And Operating Same

US Patent:
6411584, Jun 25, 2002
Filed:
Feb 19, 1999
Appl. No.:
09/256336
Inventors:
Marvin B. Davis - Colorado Springs CO
Kent T. Murphy - Colorado Springs CO
Assignee:
Discovision Associates - Irvine CA
International Classification:
G11B 1704
US Classification:
369 772, 369256
Abstract:
A cartridge unloading apparatus for a disk drive having a cartridge loading end, a remote end, and a base plate. The apparatus is employed for tiltably unloading the disk from a spindle magnet with a peeling action. The apparatus includes first and second sliders positioned relative the ends of the disk drive. The sliders each have only one S-shaped slot formed therein. Each slider has a slot to receive one of the two lifting pins provided on a cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub.

Cartridge-Loading Apparatus With Tilting Bias Coil Assembly

US Patent:
6201659, Mar 13, 2001
Filed:
Jun 7, 1995
Appl. No.:
8/486545
Inventors:
Marvin B. Davis - Colorado Springs CO
Kent Murphy - Colorado Springs CO
Assignee:
Discovision Associates - Irvine CA
International Classification:
G11B 1704
US Classification:
360 772
Abstract:
The mechanism for loading and unloading a disk cartridge uses two sliders (one on each side of a base plate), which move in opposite directions under the influence of a tiller. Each slider has a slot to receive one of the two lifting pins provided on the cartridge receiver. The movement of the sliders drives the lifting pins along the slots, thereby raising or lowering the cartridge receiver depending upon the direction of rotation of the tiller. The sliding motion of the lifting pins engaged in the S-shaped slots thus unloads a disk from or, alternatively, loads the disk onto the drive spindle. As the lifting pins travel along their respective slots, the lifting and lowering of the disk is accomplished in such a manner that the disk hub is peeled from the spindle magnet rather than being lifted vertically off the spindle. This reduces the peak force required to break the magnetic clamp force between the spindle magnet and the disk hub. In this system, the dust door is attached to the cartridge receiver, and the label end of the loaded cartridge remains visible when the disk is loaded.

Flexible Strip Cable With Extension For Testing

US Patent:
5700979, Dec 23, 1997
Filed:
Apr 7, 1995
Appl. No.:
8/418738
Inventors:
David E. Lewis - Black Forest CO
Kent T. Murphy - Colorado Springs CO
Assignee:
Discovision Associates - Irvine CA
International Classification:
H01B 708
US Classification:
174117F
Abstract:
A flexible strip test cable is disclosed having an elongated flexible strip cable, a series of strip traces disposed lengthwise on the flexible strip cable and having electrical strip contacts near one end of the flexible strip cable, an extension cable integral with the flexible strip cable and having a width at one end greater than the width of the flexible strip cable, and a series of test traces on the extension cable having electrical test contacts near the end of the extension cable remote from the flexible strip cable. Each of the test traces is electrically connected to one of the strip traces, and the minimum distance between two test contacts is greater than the minimum distance between two strip contacts. The flexible strip test cable may have a tooling guide for aligning a cutting tool with the end of the flexible strip cable which is connected to the extension cable. Alternatively, the test contacts may be electrically accessible through one surface of the extension cable in any pattern such that the minimum distance between two test contacts is greater than the minimum distance between two strip contacts.
