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： An apparatus and method for the controlled dynamic braking of a DC motor in a tape transport device are provided. A PWM state device includes a plurality of state transition paths, each path having an initial state, representative of a tape profile, including a predetermined range of tape velocities, relative amounts of tape on each reel and an initial tape tension, and at least one subsequent state. When a low power event is detected, one of the state transition paths is selected, based upon a current tape profile, and an associated PWM signal is transmitted to the motor. An energy storage device provides power to the PWM state device during the low power event. The PWM signals follow the selected transition path to modulate the current generated by the motion of the motor and thereby create a decelerating force while substantially maintaining the initial tape tension.

摘要： An inexpensive, high performance error detecting and correcting system capable of handling multiple errors with high throughput. Digital data is provided to a reconfigurable decoder which is initially set for a low level of correction and a high throughput. On detection of an error, a signal is generated which is used to dynamically reconfigure the decoder. The decoder is reconfigured at a higher correction level. The data is then reprocessed through the reconfigured decoder. In a specific implementation, the invention uses a Blahut decoder. N and K values to reconfigure the decoder are provided by a microprocessor. The invention contemplates use of an encoder operating at the highest level of correction required. Use of an initial low level of correction provides for a high throughput. Reconfigurability allows for high corrective power and associated lower throughput only when necessary.
