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.
Early IBM tape drives, such as the IBM 727 and IBM 729, were mechanically sophisticated floor-standing drives that used vacuum columns to buffer long u-shaped loops of tape. Between servo control of powerful reel motors, a low-mass capstan drive, and the low-friction and controlled tension of the vacuum columns, fast start and stop of the tape ...

A reel of half-inch magnetic tape being loaded onto an IBM 729 tape drive that is attached to an IBM 1401 being ...
A reel of magnetic tape is being loaded onto the drive. The operator's finger is holding the tape in place on the take-up reel as he takes a few turns to secure the tape leader. An IBM 1403 line printer is in the foreground. The IBM 729 Magnetic Tape Unit was IBM's iconic tape mass storage system from the late 1950s through the mid-1960s. Part ...
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.
A takeup reel is embedded inside the tape drive. Because of their speed, reliability, durability and low media cost, the 3590 tape drives are still in high demand. A hallmark of the genre is interchangeability: Tapes recorded with one tape drive are generally readable on another drive, even if the tape drives were built by different ...
The IBM 3592 is a series of enterprise-class tape drives and corresponding magnetic tape data storage media formats developed by IBM. The first drive, having the IBM product number 3592, was introduced under the nickname Jaguar. The next drive was the TS1120, also having the nickname Jaguar. As of October 2023, the latest and current drive is ...
A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data. As a result, tape drives have very large average access times ...
