While specifications vary between different drives, a typical LTO-7 drive will take about 15 seconds to load the tape and 20 seconds to unload the tape. These drives have an average rewind time of 60 seconds and an average access time (from beginning of tape) of about 56 seconds. [51]
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 ...
UNIVAC computer with a row of UNISERVO tape drives on the right. The UNISERVO tape drive was the primary I/O device on the UNIVAC I computer. It was the first tape drive for a commercially sold computer. The UNISERVO used metal tape: a 1 ⁄ 2-inch-wide (13 mm) thin strip of nickel-plated phosphor bronze (called Vicalloy) 1200
9-track tape drive used with DEC minicomputers Inside a 9-track tape drive. The vacuum columns are the two gray rectangles on the left. A typical 9-track unit consists of a tape transport—essentially all the mechanics that moves tape from reel to reel past the read/write and erase heads—and supporting control and data read/write electronics.
The first 3480 tape drives were introduced in 1984. The IBM 3480 was the first tape drive to employ magnetoresistive (MR) heads and the first to use chromium dioxide tape. One way the format stands out from earlier formats is that the gap between blocks is too small for the drive to stop the tape within it, so the drive must have a write buffer.
There are at least four main models of the 1530/C2N Datassette: The original modified Sanyo M1540A cassette drive, built into the earliest models of PET in 1977. This was a standard shoebox tape recorder with a corner of the case removed and modified electronics; a Commodore PCB was installed internally in place of the Sanyo electronics.
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...
