Travan is an 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. [1] Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length.
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 ...
Early half-inch tape had seven parallel tracks of data along the length of the tape, allowing 6-bit characters plus 1 bit of parity written across the tape. This was known as 7-track tape . With the introduction of the IBM System/360 mainframe, 9-track tapes were introduced to support the new 8-bit characters that it used.
[8] [9] The name was soon applied to the entire line of 3M tapes. Scotty McTape, a kilt-wearing cartoon boy, was the brand's mascot for two decades, first appearing in 1944. [10] The familiar tartan design, a take on the well-known Wallace tartan, was introduced in 1945. [10] The Scotch brand, Scotch Tape and Magic Tape are registered ...
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
Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...
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
The lead-in at the start of the file produced a steady tone that was used to measure the actual data rate on the tape, which might change due to tape stretch or differences between machines. During a read, the system set an input timer to the maximum value of $3FFF and then read one byte.
