Article of manufacture to automatically clean a tape drive
View Patent ↗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.
1. An article of manufacture including a non-transitory data storage medium, said data storage medium including a set of machine-readable instructions that are executable by a processing device to implement an algorithm, said algorithm comprising the steps of:
detecting a degraded status of an input/output transducer of a tape drive;
selecting and inserting a cleaner cartridge into the tape drive, said cleaner cartridge including a cleaner tape, wherein the cleaner tape contains timing-based servo information;
wherein the cleaner cartridge includes an aggressive cleaning frontcoat section; and
wherein the aggressive cleaning frontcoat section includes particles chosen from the group of oxide-coated iron metal particles, chromium dioxide, alumina, chrome-3, and silicon dioxide;
moving the cleaner tape over the input/output transducer;
reading said timing-based servo information from the cleaner tape; and
ascertaining a cleanliness status of the input/output transducer based on the timing-based servo information read from the cleaner tape.
2. The article of manufacture of claim 1 , wherein the timing-based servo information includes servo stripes.
3. The article of manufacture of claim 2 , wherein the timing-based servo information includes alpha-numeric information.
4. The article of manufacture of claim 3 , wherein the alpha-numeric information includes linear position (“LPOS”) information.
5. The article of manufacture of claim 1 , wherein the cleaner cartridge includes an aggressive cleaning frontcoat section.
6. The article of manufacture of claim 5 , wherein the aggressive cleaning frontcoat section includes particles chosen from the group of oxide-coated iron metal particles, chromium dioxide, alumina, chrome-3, and silicon dioxide.
