Abstract
A magnetic head for multi-track data recording on magnetic tape is formed of a combination of two head modules, each having a linear array of thin-film transducer elements formed on a substrate, each of these arrays consisting of a mixture of write elements and read elements. These are positioned on the respective head modules such that when the head modules are combined with the substrates mutually opposing, pairs of transducer elements are formed for respective tape tracks, each pair consisting of a read and a write element. 'Read-after-write' recording confirmation can thereby be implemented together with bidirectional recording operation, by using only a combination of two head modules.
