In some applications of tape drives, it is desirable to be able to create tapes on a tape drive normally recording at a high track density such that they can be read on a tape drive having a lower track density. This may be accomplished by providing the high track density tape drive with a selectively energizable write element which records a wider track than the tracks recorded by the normal write elements. The figure shows a schematic representation of a high density four-track head configuration having a wider element. The head 1 is designed having a group of read elements 2 and write elements 3. Each of the read elements 4, 5, 6 and 7 and write elements 8, 9, 10 and 11 is of a width corresponding to the high track density to be recorded or read by the tape drive.
