Abstract:
Dynamic reconfiguration-switching of motor windings is optimized between winding-configurations. Acceleration is traded off in favor of higher velocity upon detecting a tape storage drive is at an optimal angular-velocity for switching to an optimal lower torque constant and voltage constant. The total back electromotive force (BEMF) is prohibited from inhibiting further acceleration to a higher angular-velocity.
Abstract:
An apparatus and method are disclosed to detect and repair an error condition in a device comprising a computer readable medium comprising computer readable code. The method supplies an engineering server comprising a configuration control database in communication with a product failure alert assembly. The method then interconnects the product failure alert assembly with a product comprising a computer readable medium comprising computer readable code. The method provides product failure information to the engineering server, identifies one or more error conditions, identifies one or more fault symptom codes, determines if the configuration control database comprises one or more code updates associated with those one or more fault symptom codes, and installs those one or more code updates on the product.
Abstract:
Embodiments of the disclosure relate to a biosample cartridge that includes storage slots for holding biosample plates. The cartridge has the same form factor as data tape cartridges to allow the cartridge to be handled by the same robotic mechanisms that handle data cartridges in an automated tape library. One aspect of the disclosure concerns a biosample storage cartridge that has a movable door to provide access to inside the cartridge and a plate holder disposed inside the cartridge. The plate holder includes a plurality of slots for receiving biosample plates that are scanned and processed by the automated tape library.
Abstract:
An apparatus, system, and method are disclosed for calibrating a holographic storage device. A read channel reads a factory-stored hologram from a holographic media. A calculation module calculates a read difference between the read factory-stored hologram and a first holographic pattern that digitally describes the factory-stored hologram. In one embodiment, a calibration module calibrates the read channel with the read difference.
Abstract:
A method to align the write channel portion of a holographic data storage system, wherein the method establishes a write threshold correlation factor, provides a reference beam, and illuminates a holographic data storage medium encoded with a write reference orientation image with the reference beam to generate a write channel alignment data beam including a projected write reference orientation image. The method projects the write channel alignment data beam onto an optical detector, and calculates a first write correlation factor using the projected write reference orientation image, a stored write reference orientation image, and the tangential matched filter. If the method determines that the first write correlation factor is greater than or equal to the write threshold correlation factor, then the method determines that the spatial write channel is properly aligned.
Abstract:
Provided are a method, storage controller, and tape drive for adjusting read heads based on misregistration calculated from servo patterns. A plurality of first read heads read a plurality of servo patterns on a storage medium. A determination is made from the read servo patterns a skew at which the first read heads are positioned with respect to the servo patterns written to the storage medium. A determination is made of an adjustment factor to eliminate the determined skew. A plurality of second read heads that read the storage medium are adjusted by the adjustment factor.
Abstract:
A data storage cartridge comprises data storage media configured to store data for read and/or write access, wherein the data may be arranged in a plurality of partitions; and a plurality of cartridge memories. A control system, for example of a data storage drive, is configured to allocate at least portions of capacity of the data storage media to cartridge memories of the data storage cartridge; and to provide information defining the allocated portions of capacity to the cartridge memories. Each of the cartridge memories may have a separate user and thus provide access for that user to separate partitions.
Abstract:
A holographic storage drive of a holographic data storage system is configured to write and read holograms with respect to a plurality of locations of a holographic storage medium; and a control is configured to operate the holographic storage drive to write a known image aggregated with data in the form of a hologram to the holographic storage medium; to operate the holographic storage drive to read back the written hologram, employing a partial matched filter to cross-correlate the read-back image with the ideal version of the known image, excluding the remainder of the written hologram; and to determine whether the cross-correlation at least meets a write/readback threshold.
Abstract:
Embodiments of the disclosure relate to a cartridge that includes slots for storing biosample capillary tubes. The cartridge has the same form factor as data tape cartridges to allow the cartridge to be handled by the same robotic mechanisms that handle data cartridges in an automated tape library. One aspect of the disclosure concerns a cartridge comprising an enclosure that includes a movable door to provide access to a tube holder in the enclosure. The tube holder includes cylindrical holes or slots for receiving capillary tubes which contain biosamples scanned and analyzed an automated tape library.
Abstract:
The invention relates to the identification of molecules using electromagnetic write-heads and magneto-resistive sensors. In one embodiment, an electromagnetic write-head magnetically excites a molecule with an alternating magnetic field. A magneto-resistive sensor measures the resonant response of the magnetically excited molecule. A processor compares the resonant response to a table of known responses of different molecules to identify the chemical composition of the target molecule.
