Abstract
Taped data copying is disclosed having the capability of high speed simultaneous generation of multiple data copies. Storage media, for example magnetic tape, having data, normally in digital form, recorded thereon is read at a master unit and electrical signals indicative of the data is generated and broadcast over a computer bus to a plurality of addressable memory units where data-indicative information is simultaneously written into the plurality of memory units. Each memory unit is connected with a different associated one of a plurality of magnetic tape-containing data copying units so that data-indicative information stored in each memory unit is read and reliably copied onto the tape at the associated data copying unit. A processing unit is included to control writing information into the memory units, reading information stored in the memory units, and verifying the integrity and content of data copies.
