摘要:
A data storage disk cartridge having a dual housing structure includes an inner housing that contains a disk, and an outer housing that contains the inner housing. The inner housing is at least partially removable from the outer housing for insertion into a disk drive. The outer housing remains external to the disk drive, however, except for a portion that is inserted into the drive to provide a docking channel for retraction of the inner housing. A shutter on the inner housing covers a portion of the disk, but is manipulable by the disk drive to uncover the disk and allow drive access. The dual housing structure of the cartridge is capable of significantly improving disk and drive reliability, particularly for recording applications that require higher areal recording densities, such as near field optical recording. In particular, the disk cartridge reduces the accumulation of debris on the disk and drive components. The dual-housing disk cartridge provides a system of partially redundant barriers that significantly reduce the possibility of debris accumulation. The barriers form a hierarchy of cleanliness that stands between the outside environment and the disk and drive components. Consequently, in a preferred mode, the disk is never exposed to the outside environment. The reduced amounts of debris contribute to more consistent optical and mechanical performance of the disk and drive, and thereby enhance data storage reliability.

A latch system couples precision frames in a way that does not over-constrain the coupled frames. The position of a female latching device mounted to one precision frame is adjustable so that, prior to coupling, the latching device can be aligned to a fixed pin that is part of a fixed pin assembly mounted to a second precision frame. Once positioned, the female latching device is fixed in position with respect to the pin and mechanically coupled to the pin, so that the first and second precision frames are not distorted when the coupling takes place. Such latch systems can be used to provide a rigid and over-constrained connection between two structures that does not contain interference fits or the resultant deflection associated with interference fits.

Techniques and devices for using fibers that are angle-polished to reduce the adverse effects of optical reflection. Each fiber is mounted so that the longitudinal direction of the fiber core forms an angle with respect to an optical axis of a device along which an optical beam is coupled to or from the angle-polished end facet of the fiber.

A system secures a cartridge inserted into a data storage device. The system includes a slidable member with a recess positioned therein; a toggle pivotably mounted in the recess, the toggle having a tip to pivot the toggle upon contacting the cartridge; and an interlock unit coupled to the slidable member and adapted to engage the toggle when the toggle pivots.

An apparatus opens, closes and locks a data storage device door. The apparatus includes a linkage adapted to actuate the door, the linkage having a handle with a notch and an edge; a flag having a pin mounted thereon, the pin being adapted to engage the edge when the door opens and to be seated in the notch when the door is locked; and a lever to actuate the flag.
