A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and long archival stability. A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access ...
CDC used IBM-compatible 1 ⁄ 2-inch (13 mm) magnetic tapes, but also offered a 1-inch-wide (25 mm) variant, with 14 tracks (12 data tracks corresponding to the 12-bit word of CDC 6000 series peripheral processors, plus 2 parity bits) in the CDC 626 drive. [10] Early IBM tape drives, such as the IBM 727 and IBM 729, were mechanically ...
The end of the tape is attached to a perpendicular leader pin that is used by an LTO drive to reliably grasp the end of the tape and mount it in a take-up reel inside the drive. Older single-reel tape technologies, such as 9-track tape and DLT, used different means to load tape onto a take-up reel. When a cartridge is not in a drive, the pin is ...
The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
These drives used Advanced Metal Evaporated (AME) tape with a 2 m integrated cleaning tape header called Smart Clean. 1999—Mammoth-2 12 MB/s data transfer rate; 4.6 cm/s tape speed during normal read/write operations; 1.6 m/s tape speed during search and rewind operations; 17 s load time, from insertion to ready
A rotating drive's average seek time is the average of all possible seek times which technically is the time to do all possible seeks divided by the number of all possible seeks, but in practice it is determined by statistical methods or simply approximated as the time of a seek over one-third of the number of tracks.

The cartridges contain a single reel and the tape is pulled out of the cartridge by means of a leader tape attached to the take-up reel inside the drive. The drive leader tape is buckled to the cartridge leader during the load process. Tape speed and tension are controlled electronically via the reel motors; there is no capstan. The tape is ...
