ABSTRACT:
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.
