Appendix B. Tape handling

This section describes how to properly handle your tape cartridges to reduce wear on the 100/200 GB HH LTO Internal Tape Drive.

Tape handling and storage

Most tapes are supplied in sealed cartridges. Tapes are provided this way so that the tape will remain in a clean environment. Opening the cartridge enables dirt and airborne particles to enter and contaminate the cartridge. The cartridge must only be opened by the tape drive and not by an operator. The tape is also held under proper tension inside the cartridge. If the cartridge is dropped, this tension is relaxed. Inserting a dropped cartridge into a tape drive can often cause a misload that results in a jam. The jam ruins the tape and can cause physical damage if the cartridge is not removed properly. When you store tapes, place them in their protective containers and store them on their ends. Store the tapes in a clean, dry area at normal room temperature and away from magnetic fields.

Environmental issues

The operating environment might adversely affect tape drive operation. The tape drive is designed to operate in a clean environment. When tape is installed in a tape drive, the clearance between the heads and the tape is measured in microns. Even particles of smoke are larger than the space available between the tape and the heads. Other environmental factors that adversely affect tape drive operation are dirt, dust, fibers, and airborne particles. Ensure that you operate in a clean environment.

Tape drive cleaning

Even if the operating environment is clean, dirt might build up on the heads of any tape drive. Every time tape motion occurs, some of the media surface comes off on the heads. Over time, this material builds up, causing the tape head clearance to increase. The increased tape head clearance produces reading and writing errors. Most tape drives today have a built-in cleaning indicator to notify you when the tape needs cleaning.

Do not use any non-LTO cleaning cartridges with these tape drives. You can use cleaning cartridges only for a limited number of times. A cleaning cartridge is expired after it has been used for the maximum number of times as indicated. When a cleaning cartridge is expired, you must replace it. Never reuse an expired cleaning cartridge. If you continue to use an expired cleaning cartridge, you might reintroduce dirt to the tape drive and you might not clean the drive. To make sure that you know when your cleaning cartridge expires, make a notation on the cleaning cartridge each time you clean the tape drive.
