摘要:
A system and method for automatically executing a participating application upon insertion of a removable media into a computing device. When the computing device detects that the removable media containing has been inserted, a task disk control file is read from the removable media. The task disk control file contains all of the configuration information necessary to run the participating application from the removable media The participating application is then launched for use by a user. After the user is finished using the participating application, the removable disk is automatically ejected. In addition to monitoring for insertion of the removable media, events such as a completion of the self-contained application and a request to eject the media are monitored. When a completion event is encountered, all data files are saved, temporary files deleted and configuration information removed prior to the removable disk ejection. When an ejection event is encountered, the computing device is instructed to wait until the completion events are executed prior to actual ejection of the removable media.

An improved head assembly having air bearing features for contaminant control in flexible media high contact-pressure zone. The head assembly having one or more air bearing features for improving the performance of the heads by controlling a flow of contaminants away from the head sensor and the high contact-pressure zone. The improved head assembly having air bearing features allows the head to keep contaminants out or the high contact-pressure zone proximate the head disk interface where the sensor communicates (e.g., contacts) the flexible media. The head assembly of the present invention includes a shaped slot air bearing feature formed in the rail having the sensor that directs the flow of contaminants away from the high contact-pressure zone and therefore, away from the sensor. This helps to prevent problems associated with head spacing and also damage to the head, the disk, and/or both. In addition, the present invention can also include and additional shaped slot air bearing feature positioned by the sensor. In another embodiment of the present invention, the head assembly has a shaped rail air bearing feature for controlling a flow of contaminants from entering the high contact-pressure zone and away from the sensor.

A magnetic head/write assembly for a flexible disk drive has rails (14, 15) with slots (18, 19) between the ends thereof. These slots (18, 19) provide an air bleed in the air bearing surface of the rails (14, 15). The air bleed capacity of the slots (18, 19), the width of the rails (14, 15) and the load force applied by the flexures (20) provide optimal width of the rails (14, 15) for stabilizing the media (13) while maintaining a low fly height of the electro-magnetic elements (16, 17) on the media (13).

A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region. The written first data is not accepted where the portions of the body are indelibly altered. Accordingly, the read second data corresponds to the written first data with segments thereof missing. The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

A scanning device has a scanning portion and an integral storage device. The scanning portion optically scans an image and converts the scanned image into a digital image, and provides the digital image at an output. The integral storage device has an input for receiving the digital image and a bay for receiving a removably insertable storage cartridge inserted thereinto. The received storage cartridge stores the received digital image therein.

Performance improvement during a track following operation in a disk drive is achieved by dedicating hardware to monitor specific anomalies during track following and to interrupt the processor only when specific, programmable criteria have been violated. An exemplary system comprises a servo miscue detector for checking (100) a servo sector for a miscue; a miscue counter coupled to the servo miscue detector for counting (110) a number of miscues; counter reset logic (105) coupled to the miscue counter; a comparator for comparing (115) the number of miscues to a predetermined threshold to generate an output; generate interrupt logic for generating (120) a microprocessor interrupt responsive to the output of the comparator; and a microprocessor to initiate an error recovery sequence (125) responsive to the controller. The servo miscue detector, the miscue counter, the counter reset logic, the comparator, and the generate interrupt logic are implemented in hardware.
摘要:
A system and method for applying a thick layer of luminescent emissive material, such as phosphor, to a substrate, such as a data storage cartridge, is provided whereby a luminescent emissive material is mixed with a binder, the mixture is dispensed onto a mesh screen placed over a substrate, and the mixture is then pushed through the mesh screen and applied to the substrate at a predetermined thickness. The predetermined thickness of the deposited phosphor layer is preferably between about 8 and 12 mils.

The presence of a disk cartridge (10) in a disk drive (40) is detected by obtaining a measure of the load on the spindle motor (82) of the disk drive and comparing that measure to a threshold value. The measure of load on the spindle motor may comprise (i) the time the spindle motor takes to spin-up to its full operating speed, (ii) the time the spindle motor takes to coast down to its operating speed from a first speed in excess of the operating speed, (iii) the voltage applied across the coils of the spindle motor, or (iv) the current drawn by the spindle motor.
摘要:
A head loading apparatus for a disk drive device is disclosed that limits the velocity of the heads during loading of the heads onto the surface of a data storage medium. The apparatus is characterized by varying a voice coil current or voltage during the head loading process. The varying current or voltage nudges read-write heads off of a load ramp and onto the surface of a data storage medium.
摘要:
A disk cartridge having a rotary inner shell to permit access to the media. The cartridge comprises a driving access opening in a bottom surface thereof to allow a drive mechanism to rotate a medium disposed within the shell. The inner shell comprises a projection into the driving access opening to aid in the rotational alignment of the inner shell. The cartridge has a wedge shaped disk access opening that rotates over a predefined angular portion of the cartridge to expose the medium disposed therein.
