Abstract
PURPOSE:To form recording tracks of high density by projecting an erasing head, preceding a recording-reproducing head, with a level difference from the recording- reproducing head and by forming a guard band between adjacent tracks there. CONSTITUTION:Preceding recording-reproducing head 31 in contact with a running magnetic tape, separate-track erasing head 32 in contact with the corresponding magnetic tape track part is projected with level differences from recording-reproducing head 31 in the direction of head movement and in the opposite direction. Then, side edge part of adjacent recording tracks are erased by this projecting step part to form gurad band S between tracks. For example, recording reproducing head 31 and erasing head 32 are combined in one body to constitute head 23 and while track width Th of recording-reproducing head 31 is set to Tp+alpha a little bit wider than track width Tp on the recording pattern, track width TEh of erasing head 32 is set to P+alpha a little bit wider than pitch P of the recording pattern.
