摘要： A cartridge handling system and method are provided to initialize a data storage cartridge having rewritable media and a cartridge memory for tamper resistant write once recording. During initialization of the cartridge for write once recording, selected data set information table fields of each data set are scrambled. The scrambling algorithm may employ a random number generator seeded with a unique cartridge identifier. The fields thus becomes unreadable if the unique identifier is changed, such as if the cartridge memory of the cartridge has been altered or replaced.

摘要： Synchronized data is written to magnetic tape while reducing the number of backhitches. A controller detects a pattern of synchronizing events for received data records to be written to tape; writes each transaction of data records to the magnetic; tape; accumulates the synchronized transactions in a buffer; and subsequently recursively writes the accumulated transactions of data records from the buffer to the magnetic tape in a sequence. A single backhitch may be employed to place the recursively written accumulated data records following the preceding data, maximizing performance and capacity.

摘要： Provided are a method, system, and program for writing data in a tape medium having wraps. A layout of the tape is provided including at least one segment within a full available length of a first set of wraps for writing user data and at least one segment within a full length of a second set of wraps for writing a work copy of the user data. User data is received to write to the tape medium and detecting is performed as to whether the data being written is occurring in a specified write mode. If the data writing is not occurring in the specified write mode, then writing the received user data to one segment in the first set of wraps. If the data writing is occurring in the specified write mode, then writing a work copy to available full length wraps not having user data.

摘要： A read channel and method using that read channel are disclosed. The read channel comprises an analog to digital converter which asynchronously samples at a fixed rate an analog signal formed by reading a data track, where that data track was written to a data storage medium at a symbol rate and an interpolator interconnected with the analog to digital converter. The read channel further comprises a fractionally-spaced equalizer, where the interpolator provides an interpolated signal to the fractionally-spaced equalizer at an interpolation rate, where that interpolation rate is greater than the symbol rate. The fractionally-spaced equalizer forms a synchronous equalized signal. The read channel further comprises a gain control module interconnected with the fractionally-spaced equalizer, and a sequence detector interconnected with the gain control module.

摘要： An apparatus, system, and method are disclosed for mitigating signal asymmetry. An analog to digital converter samples an analog signal from a read head and converts the sample to a digital input signal. The digital input signal addresses a look-up module, and the look-up module outputs a modified digital signal. The modified digital signal value is a specified function of the digital input signal value, wherein the specified function is configured to mitigate the asymmetry of the digital input signal. The modified digital signal value may be periodically recalculated to adjust for read head wear.
