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.
Most (but not all) modern tape cartridges are 1 ⁄ 2 in (13 mm) format tape, first popularized by the IBM 3480 and DEC DLT formats. This is a small, rectangular and easily handled tape cartridge compared to the previously common 7-track and 9-track round tape reels.
9-track tape is a format for magnetic-tape data storage, introduced with the IBM System/360 in 1964. The 1 ⁄ 2 inch (12.7 mm) wide magnetic tape media and reels have the same size as the earlier IBM 7-track format it replaced, but the new format has eight data tracks and one parity track for a total of nine
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 ...
Cassette tape, a two-spool tape cassette format for analog audio recording and playback and introduced in 1963 by Philips; DC-International, a format that was created by Grundig after Phillips had abandoned an earlier format that was being created alongside the Compact Cassette; 8-track tape, continuous loop tape system introduced in 1964
Although the physical tape was nominally the same width in these new formats and the preceding open-reel formats, the technologies and intended markets were significantly different and there was no compatibility between them. The IBM 3480 tape format was designed to meet the demanding requirements of its mainframe products. DEC's CompacTape was ...
They can store up to 60 GB of data (uncompressed). This family superseded the IBM 3480 Family of tape drives popular in 1980s and 1990s. 3592 Series tape. Like the 3480 and 3592 formats, this tape format has half inch tape spooled onto 4-by-5-by-1 inch data cartridges containing a single reel. A takeup reel is embedded inside the tape drive.
The TX-2 Tape System is the direct ancestor of LINCtape, including the use of two redundant sets of five tracks and a direct drive tape transport, but it uses a physically incompatible tape format (½-inch tape on 10-inch reels, where LINC tape and DECtape used ¾-inch tape on 4-inch reels).
