ABSTRACT:
A magnetic recording/reproducing device for recording/reproducing information signals for one recording unit over a plurality of recording tracks by helically scanning a magnetic tape with rotary heads. The information signals for one recording unit are recorded on the plurality of recording tracks on the magnetic tape, and guard bands are formed simultaneously between the one recording units. The recording density is substantially improved. Erase heads overwrite the information signals on the magnetic tape and the plurality of recording tracks for one recording unit on the magnetic tape are erased en block, which prevents over-erasing unerased portions during editing.
