Data transfer Rate:

Data transfer Rate: Data transfer rate refers to number of characters per second, which can be transmitted to the primary storage from the tape. it is measured in bytes per second (bps), its value depends it on the {data.recording}..density, and-the speed. with which {the tape} travels under the read/write head, Tape speed is typically of the order of 100 inches per second. therefore a tape having data recording density of 77,000 bpi. and its drive having a tape speed of 100 inches per second. will have a data transfer rate of 7,000+100=77,00,000 bytes or 7.7 MB per second.
