摘要： An optical data storage disk includes a central substrate and on each side of the substrate a pair of metal/alloy recording layers separated by a transparent layer, preferably made of a photopolymer resin. Thus the disk includes a total of four recording layers. The disk is a "first-side" disk, in the sense that the laser beam used to read and write data enters the disk from the same side as the layer to be read or written, i.e., the laser beam does not pass through the central substrate. The disk is manufactured by a process that includes coating the inner metal/alloy layers with the photopolymer resin in liquid form, embossing the data for the outer metal layers on the photopolymer resin coatings with a transparent stamper, and then curing the photopolymer resin by directing UV radiation through the transparent stamper.

摘要： A system, method, and apparatus for coordinating tasks in a control system for an optical disc drive for optical media with a pitted premastered area that cannot be overwritten and a grooved user-writeable area that can be overwritten. The optical disc drive includes a first processor operable to communicate with a second processor, wherein the first processor includes instructions for performing non-time-critical tasks, and the second processor includes instructions for performing time-critical tasks, such as reading from and writing to optical media in the disc drive. The first processor monitors the status of the time critical tasks in the second processor and transmits commands to perform operations in the second processor. The first processor also controls power mode, manages recovery from errors, controls focus, tracking/seeking, spin, physical sector address (PSA), a laser, adjusts gains, and monitor cartridge load/eject. The first processor sequences and monitors functions performed in the second processor and the second processor issues an interrupt when an error condition is detected in the second processor. The first processor detects the interrupt, and disables detecting further interrupts until the interrupt is serviced. Servicing the interrupt includes recording the error state and changing focus and tracking parameters based on the error condition detected. The first processor can be used to perform other tasks while it is waiting to receive a notice of a new command, a notify event, or a performance event.

摘要： Extremely small optical heads are being developed for use in optical storage devices. The heads typically include a light source, a lens and a photodetector array. The beam of light generated by the light source must be aligned precisely with central axis of the lens and with the photodetector array. Because the heads are so small, their components are fixed permanently together; no adjustments are possible after assembly. A system of this invention includes a rotational stage, a pair of X-translation stages, and a pair Y-translation stages. The stages are mounted in a mechanical path between first and second holding devices. One component of the head, which would typically include the light source, is held in the first holding device. Another component, which would typically include the lens, is held in the second holding device. The stages are adjusted until the light beam exits the first component on an axis that coincides with the center of rotation of the rotational stage. The position of the second component is adjusted until the light beam coincides with the axis of the lens. The first component is then rotated until the light beam strikes the photodetector array at an optimal position. The optimal position can be obtained by directing the light beam at a media driven by a tracking actuator and optimizing the output signal from the head.

摘要： A file system for accessing information on digital storage media is provided by a storage device controller embedded within the storage device. The storage device controller includes an interface component to receive a packet having a file system command. A command decode component in the storage device controller decodes the file system command, and an interface response structure component creates a strategy for performing the file system command. The storage device controller generates an identifier for a file system object and accesses the file system object using the file system object's identifier. A host system coupled to the storage device receives a storage device access request from an application program and generates a command to perform on the file system object based on the storage device access request. The host system uses the identifier to indicate the file system object to be accessed.

摘要： A digital optical information disk contains content and/or non-content information on both sides of a single substrate produced by a process that embosses the surfaces of both sides substantially simultaneously. Simultaneous molding substantially eliminates the need for lamination when two or more data layers are to be provided. Preferably, the disk is relatively small, such as less than 50 mm in diameter and can replicate marks or features with a z-dimension magnitude of about 80 nm or more. The disk remains within a specified opto-mechanical range of an optical transducer and has little, if any, non-planarity (warp) or other distortion. The disk can be used for reading pre-written or mastered content, e.g., in a user's device, and/or can include information or features that permits or supports utility functions, allowing the user to record data thereon such as tracking, sector, location, timing, synchronization features or combinations thereof. Preferably, the disk is formed by an injection-only technique, although it is possible to provide suitable disks by an injection-compression technique as well.

摘要： A disk storage and handling magazine has a spindle mounted on a bottom cap. Disks are loaded in the magazine by passing the spindle through a hole in the center of the disks. The disks may be separated by spacers to prevent the disks from touching each other. In some embodiments, the magazine includes a tube surrounding the spindle and a removable top cap fitting over the spindle and the tube. The magazine also includes a jacking mechanism that moves up and down the spindle for automatically unloading disks from the magazine. The jacking mechanism has a jacking plate mounted on at least one plug. The at least one plug seats in a hole in the bottom cap of the magazine to form an airtight seal when the jacking mechanism is at the bottom of the spindle.

摘要： A method and apparatus for storing, updating, adding, deleting, and locating file system objects on a WORM storage medium, wherein information can be written to, but not erased from, the storage medium. The WORM storage medium has a writeable area that includes a system area and a data area. The system area includes system information regarding the file system objects on the storage medium. A system sector is written starting at one end of the system area, while the content of the file system objects is written in the data area starting at another end of the writeable area. When a change is made to the file system objects in the writeable area, an updated system sector is generated that replaces the previous file system information for those modified file system objects. Since the previous system sector is not erasable, the updated system sector is written in a location in the system area where it will be read before any previous system sectors. The updated system sector overrides file system information in previously generated system sectors. The information required to access all the file system objects on the storage medium may be included in the updated system sector, or in the updated system sector along with one or more of the previously generated system sectors.

摘要： A crimping tool is used to attach a metal hub plate to a plastic hub for a data storage disk. The hub is bonded to the data storage disk, and the metal hub plate allows the disk to be magnetically clamped to a spindle of a disk drive. The metal hub plate has a four tabs which are bent into respective recessed areas of the hub. The tool includes a plunger (50) which is directed against the metal hub plate which the plate is held in a lower die assembly. The plunger includes four crimping jaws (524) which slide against angled surfaces of the plunger. The sliding motion causes the crimping jaws (524) to move radially inward towards each other. The lower surface of each jaw includes a cam surface and a prow. The cam surface slides against the tab, bending it to a predetermined shape, and then the prow contacts a base of the tab to bend it beyond the predetermined shape. In this way, the tabs, which are typically made of a resilient metal, are forced into the recessed areas and remain entirely within the recessed areas despite any spring-back that may occur after the bending has been completed.
