    摘要: A data flow control and bridging architecture that enhances the performance of removable data storage systems. In one implementation, the present invention provides a bypass bus implementation where the data transfer phase associated with select commands occurs directly between the host computing system and the target removable data storage unit. In one implementation, the present invention further provides a data flow and bridging architecture that emulates a removable media interface, such as the ATAPI interface, to the host computing system, and translates these commands for a target removable storage unit that implements a fixed media interface, such as the ATA interface. In yet another implementation, the present invention provides a data flow and bridging architecture that supports the serial ATA interface.

    摘要: The present invention, in particular embodiments, provides methods, apparatuses and systems directed to a removable cartridge which has a data storage device, such as a hard drive, that contains a data archive application and a loader or installer. In one implementation, the data storage device contains platform-independent archive data, and one or more differing platform-dependent archive applications. When the removable cartridge is connected to a host with no installed archive application, an archive application on the removable cartridge, corresponding to the host operating system, may be installed. Archive data is then translated to a format compatible with the host operating system and provided to the host.

    摘要: The present invention, in particular embodiments, is directed to methods, apparatuses and systems that provide global timing error information derived from timing error information of each data channel. This is achieved, in part, by summing the timing error information from all the data channels and integrating and scaling the resulting sum. The integrated, scaled sum is then added to the proportional and integral timing information of each individual data channel. By doing so, incorrect timing error estimates are averaged out. Additionally, when severe noise and dropouts (loss of data signal) at an individual data channel occur, that channel may rely on the global timing error information. In some implementations, that individual data channel's timing error information contribution can be excluded from the global timing error information.

    摘要: An example embodiment provides for an apparatus, for use in a tape drive system, that facilitates adjustment of azimuth and zenith orientations of a magnetic tape head. The apparatus includes a top and bottom plate located above and below an actuator assembly that includes a magnetic head. Also included are first and second ball-ended guide rods that each have ends that mate with corresponding top and bottom plate sockets. Azimuth and zenith adjustment is provided for via at least one azimuth adjustment screw and at least one zenith adjustment screw. Various aspects of the apparatus include independent adjustment of the zenith and azimuth, where adjustments to one does not affect the other. Another aspect includes the top plate remaining in a substantially horizontal plane when either the azimuth or the zenith is adjusted.

    摘要: An exemplary embodiment provides for a servo-actuated, head actuator design wherein a head carriage includes one or more positional sensor location features that precisely define placement. The sensor location features are configured such that a positional sensor can be mated into a specific sensor location feature. As the head carriage is typically manufactured with great accuracy, the inclusion and placement of the sensor location features will also be extremely accurate. As a result, the location of positional sensors can be pre-defined via the head carriage design such that they will be at a precise location with respect to a magnetic head attached to the head carriage, thereby reducing variation in the location of one or more positional sensors resulting from a tape drive assembly process.

    摘要: The claimed embodiments provide methods, apparatuses and systems directed to a servo-actuated positioner for a read/write head that uses a piezoelectric super fine actuator that moves the read/write head to maintain alignment with data tracks on a magnetic tape. The servo-actuated positioner, in one implementation, uses flexures to mechanically support the read/write head. Piezoelectric elements are attached to the flexures in strategic locations to effect movement of the read/write head when the elements are actuated. This configuration achieves a large actuator motion using small piezoelectric elements. Additionally, manufacturability is improved since the piezoelectric elements, which are typically brittle, are attached to the mechanically robust flexures.

    摘要: An exemplary embodiment provides for a cable connection apparatus wherein a connector is mounted on a disk drive chassis, or a sub-assembly attachable to a chassis, such that a cable that connects to the connector will do so along an axis parallel to the chassis or subassembly that the connector is coupled to as opposed to a more typical perpendicular coupling. As a result, the cable will not stick straight out from the back of the drive and the drive footprint is also reduced.

    摘要: The present invention, in particular embodiments, is directed to methods, apparatuses and systems that facilitate recording of servo signals on a recording medium such as magnetic tape with high accuracy. Variation of inter-frame and intra-frame placement is substantially reduced by writing successive frames or sub-frames based on a detection of a previously-written frame or sub-frame by a read element. Appropriate placement of the read element in relation to servo write elements, on a multi-gap servo write head, ensures the correct placement of subsequent frames on the recording medium.

    摘要: The claimed embodiments provide methods, apparatuses and systems directed to run-length limited (RLL) coding of data. In one implementation, concatenatable RLL codes with run lengths of zeroes not exceeding k are constructed for any rate N/(N+1) where N≦2k−2+k−1. As code rates increase, the value of k departs from the minimum possible value more slowly than that of many other codes. Further, occurrences of k-bit run lengths occur only at the juncture of two codewords. Due to this, the codes are mostly k−1. This quality makes the codes ideal for parity bit insertion applications such as LDPC channels. The method, in one implementation, places the bit addresses of violating sequences in a table at the beginning of the codeword, and the user data, occupying the locations where the table entries are placed, are moved into the locations of the violating sequences. This is done iteratively and in a way which provides for cases in which the violating sequence is inside the address table itself.
