Abstract: A data storage system that uses multiple nested concentric carousels on a common rotating axis. Each carousel is equipped with an opening large enough to accommodate a retrieving arm, allowing the arm access to the next interior carousel. By aligning the openings of multiple carousels, the retrieving arm can access data storage cartridges located on any of the nested carousels.

Abstract: The present invention provides a virtual automated cartridge system (ACS) and data storage device management method which incorporates a temporary data buffer arrangement between multiple user systems and conventional physical data storage devices. The temporary data buffer arrangement emulates a compatible physical data storage device when accessed by each of the user systems, but allows simultaneous allocation of different users to access to read and write data to the temporary data buffer. A control processor automatically transfers data stored in the temporary data buffer arrangement to one of the physical data storage devices when allocation to a user has ended.

Abstract: Apparatus and methods for reducing the sensitivity of spin valve sensor read heads for magnetic tape applications are provided. The apparatus and methods compromise the large output gain derived from using state of the art spin valve sensors in order to reduce the flux capture and thus, the signal distortion in the spin valve sensor. In order to provide a reduced sensitivity spin valve sensor, one or more of the basic sensitivity of the spin valve, the flux carrying capability of the free layer, and the flux injection efficiency of the spin valve head structure are modified to reduce the flux capture by the sensing layer.

Abstract: A system and method for exchanging tape cartridges between two automated tape cartridge libraries. A carriage assembly carries cartridges back and forth between the libraries. The carriage assembly includes a cartridge transport cell, has a vertical axis, and cooperates with pass through ports in the libraries for providing access to tape cartridge storage cells in the libraries. A guide structure extends between the libraries for supporting the carriage assembly. The guide structure defines a linear path and has first and second sides substantially parallel to the linear path which define an envelope. The carriage assembly is driven along the guide structure, and automatically rotates about the substantially vertical axis. The cartridge transport cell is accessible by robotic devices in the libraries when the carriage assembly is aligned with the pass through ports. The carriage assembly rotates substantially within the envelope as it is driven along the guide structure.

Abstract: Disclosed is a intelligent light source that is capable of providing a uniform illumination image across the surface of an illuminated object analyzed by an optical detector. This is accomplished by individually controlling each light-emitting element of a linear array of light elements. Calibration of the array is accomplished by sequentially illuminating each optical element of the source and building an array of normalized detected data. The matrix is then inverted and multiplied by a linear array of ones to generate the calibration data. The calibration data are then used to program a simple logic device that allows accurate digital control of the intensity of each individual light element.

Abstract: A system and method for distributing electrical power to an automated robotic device for transporting media cartridges in a data storage library. A power distributor includes multiple sections having first and second electrical conductors. A first power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two section of the power distributor. A second power supply powers the first and second conductors of each section of the power distributor, and is connected to the first and second conductors of at least two sections of the power distributor. Power to each section of the power distributor is maintained in the event of a failure of one of the power supplies, and in the event of an electrical discontinuity in the power distributor.

Abstract: A transducer for generating a write signal includes a write gap layer and bottom and top poles. The write gap layer is oriented normal to a media bearing surface. The bottom pole has a first magnetic material inner layer disposed adjacent the write gap layer for coupling the write signal to the media bearing surface. The top pole has a first magnetic material inner layer and a second magnetic material outer layer. The top pole is disposed adjacent the write gap layer on a side opposite the bottom pole at the media bearing surface with the top pole inner layer disposed between the gap layer and the top pole outer layer. The top pole has a constant width at the media bearing surface and couples the write signal to the media bearing surface. A coil passes between the bottom and top poles for inducing the write signal in the poles.

Abstract: A method and system are provided for dynamically shortening a number of error correction codewords to correspond to an amount of user data to be recorded on a recording medium. The system and method determine in advance that the number of bytes of user data will only fill a portion of a codeword matrix, and automatically shortens the size of ECC word segments to match the actual user data fill. This allows an ECC interleave to be completed with only a partial fill of the matrix, thereby reducing the required number of recording passes and associated processing time.

Abstract: An adaptive trellis adaptable to read a signal having signal amplitude dropouts includes a standard partial response maximum likelihood (PRML) trellis and an estimating PRML trellis. The standard trellis is associated with a standard state diagram having standard branches between states. A first set of the standard branches produce a non-zero amplitude read signal sample and a second set of the standard branches produce a zero amplitude read signal sample. Each state of the standard state diagram has two standard branches feeding into that state. The estimating trellis is associated with an estimating state diagram having estimating branches between states. The estimating branches produce estimated read signal samples that adapt to the amplitude of the signal. Each state of the estimating state diagram has two estimating branches feeding into that state. Each standard and estimating branch has an associated error metric. Each state of the standard state diagram has two estimating branches feeding into that state and each state of the estimating state diagram has two standard branches feeding into that state. The states are connected by paths formed by branches between the states. A path error metric is the sum of all branch error metrics for all of the branches that form the path. The path arriving at one state having the lowest path error metric survives to be identified as the expected path to the next state for reading the signal.
