Abstract

PURPOSE:To achieve the improvement in performance by making combination use of the heads of the specific construction and azimuth recording system. CONSTITUTION:Plural sets of a pair of head caps (a), (b) of mutually opposite directions in azimuth each consisting of a recording core part 6 composed of magnetic material of high saturated magnetic flux density such as high saturated magnetic flux density ferrite or the like, a reproducing core part 7 composed of laminated Sendust or the like and a common winding 8 are prepared. A pair of the head caps (a), (b) are scanned in the arrow Y direction with respect to the tape running in the arrow X direction. Then, the recording locus AR by the recording core part 6 and the recording locus AP by the reproducing core part 7 are recorded by the head A of the channel A, after which the recording loci BR, BP deviated by a track pitch P are recorded by the head 2 of the channel B. Thereafter, these are reproduced by the reproducing core part 7. Hence, recording density and S/N are improved.
