Magnetic tape - Wikipedia, the free encyclopedia (1341 words) |
 | Magnetic tape is a non-volatile storage medium consisting of a magnetic coating on a thin plastic strip. |
| In the 1980's compact audio cassettes were used with home computers of the 1980s, and digital audio tape was used for backup in workstations. |
| Most tape systems attempt to alleviate the intrinsic long latency, either using indexing, where a separate lookup table is maintained which gives the physical tape location for a given data block number, or by marking blocks with a tape mark that can be detected while winding the tape at high speed. |
