摘要： A key server provides keys for encryption and/or decryption for data storage drives. A first communication link provides at least data communication with respect to the data storage drive; a second communication link, separate from the first communication link, provides communication between the data storage drive and the key server; and the key server provides the encryption and/or decryption keys over the second communication link.

摘要： An automated data storage library accesses data stored on storage media contained in cartridges in response to commands from an external host. The cartridges may include cartridge memory and a component in the library may include a cartridge memory interface for reading data from and/or writing data to the cartridge memory. When a cartridge is to be stored in the library, the library modifies the contents of the cartridge memory, or the contents of the storage media such that the data stored on the cartridge becomes inaccessible, thereby preventing access to the data outside of the library. To perform an authorized access, the library restores the contents of the cartridge memory or the storage media. Alternatively, the library provides a correction or correction algorithm to the drive to allow access to the data stored on the storage media without removing the access protection of the storage media. The cartridge memory or storage media may also or alternatively include an identifier which permits access to the data only by the identified physical and/or logical library(s).

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.

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.
