Problem
Solutions: Helical-Scan Recording: The technology that has vastly increased the capacity of compact tape drives is called helical-scan recording. Originally invented for use in broadcast systems, helical-scan recording has been used in data storage systems since the mid 1970's. Both longitudinal and helical-scan recording technologies rely on magnetism to record data on backup tapes. The basic differences between the two are the pattern in which data is recorded and the positioning of the heads used to read, write, and erase the data. Conventional longitudinal recording records a track of data straight across the width of a single-track tape, limited in size to the width of the tape (quarter inch). Helical-scan recording packs more data on the tape by positioning the tape at a 5-degree angle to the recording heads. Each data track is a 3 inch long diagonal. The magnetic tape used in helical-scan recording is of high quality. |
