    Abstract: PROBLEM TO BE SOLVED: To overcome the problem of seek error due to disturbance of tracking error signal by calculating an approximate TES signal through linear interpolation and using it in place of an actual TES signal during a time interval when a hard sector is detected. SOLUTION: A TES interpolation circuit is activated during an interval when a hard sector detection circuit generates an output pulse to calculate the voltage variation rate of a TES signal continuously using an analog differentiator. A sample hold circuit is tracked by an integrator 162 having polar and zero positions being set to cancel the effect of a differentiation circuit 152. When no hard sector is present, an original TES signal passes through the circuit as it is but when a hard sector is detected, the sample hold circuit captures the final value of TES gradient. Finally, the integrator integrates the gradient and performs linear interpolation of the TES signal.

    Abstract: PROBLEM TO BE SOLVED: To manage data storage media of a data storage cartridge and the data storage cartridge. SOLUTION: The data storage cartridge 100 comprises data storage media 105 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 104. 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. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a new and specific speed calculation of a desired type of recording media for further improving the control technique of a storage medium. SOLUTION: The speed calculator makes high order calculation of the servo/frame speed of a storage medium especially such as a tape and a disk. It uses the servo/frame indexing module for producing the primary pre-servo/frame speed signals showing the primary calculation of the pre-servo/frame speed containing the primary pre-servo/frame errors, based on the current primary servo/frame speed signals showing the primary calculation of the current servo/frame speed containing the current primary servo/frame errors. Further, it uses the speed estimation module to produce higher order current servo/frame speed signals showing the secondary or higher order speed calculation of the current servo/frame speed containing the current high order servo/frame errors, based on the primary pre-servo/frame speed signals and the current primary servo/frame speed signals.

    Abstract: PROBLEM TO BE SOLVED: To improve reliability for multi-layer media in order to enhance the security of data.
    SOLUTION: In the method for reading and writing data to a plurality of layers of a storage medium, a data stream U having a series of data bits is received and stored to a multi-layer rotating storage medium. Each data bit U(J) is encoded into X representation bits. A first representation bit B(1, J) is recorded onto a first layer of the storage medium, the second representation bit B(2, J) is recorded onto a second layer of the storage medium, etc. When a request to read the recorded data U from the storage medium is subsequently received, a plurality of the X representation bits are read back from the storage medium and are decoded into the original data bit U(J). In one embodiment, encoding may be performed with a convolution encoding algorithm and decoding with a PRML decoding algorithm. In another embodiment, Reed Solomon encoding/decoding may be employed.
