摘要： A system, a method, and article of manufacture are employed to clean the input/output transducers on tape drives, verified by the tape drives reading alphanumeric information from data tracks and servo tracks of a cleaner tape. An aggressive cleaning frontcoat section of the cleaner tape can be used to provide additional cleaning action, and the cleanliness of the data read elements, data write elements, and the servo heads. A less-abrasive cleaning section may be used to clean less difficult types of contaminants. In this manner, the cleanliness of the data read elements, the data write elements, and the servo heads can be verified. A cleaning section may also be used as a leader section of a self-characterization section. Alternatively, a magnetic data tape section may be included for self-characterization.

摘要： Various embodiments for writing received synchronized data to magnetic tape having a plurality of wraps using a magnetic tape drive adapted for performing the writing according to an available plurality of predefined tape speeds are provided. In one such embodiment, for each of the available plurality of predefined tape speeds, an average overhead per synchronized command for performing a recursively accumulated backhitchless flush (RABF) cycle is calculated. One of the available plurality of predefined tape speeds having a lowest calculated average overhead is selected. The RABF cycle is performed using the selected one of the available plurality of predefined tape speeds.

摘要： A record medium, such as a magnetic tape, optical disk, magnetic disk, and the like stores data signals and error redundancy signals. Resynchronization signals are interleaved between the recorded signals such that the error redundancy signals are usable to correct signals recorded between such interposed resynchronization signals wherein no error redundancy signals are recorded. Error pointing redundancy signals are recorded between all of the resynchronization signals for pointing to signals in error for enhancing the error correction. Such error pointing signals can be cyclic redundancy check (CRC) signals. Controls for taking advantage of the above-described arrangement are also described. Reframing and clock synchronization controls are also disclosed.
