Abstract
A magnetic recording/reproducing apparatus (VTR, Camcorder, DAT and the like) which can record and reproduce image signals and audio signals on a magnetic tape. The magnetic recording/reproducing apparatus is equipped with two magnetic head drums having mutually-opposing set-up angles and rotating directions, with one head drum for recording signals or reproducing the recorded signals on the upper domain of a tape when the tape is played in a first direction and with another head drum for recording signals or reproducing the recorded signals on the lower domain of a tape when the tape is played in an opposite direction. The magnetic recording/reproducing apparatus can record or reproduce in both directions, eliminating the drawback of compulsory rewinding after reproduction, and thus enabling long duration of recording and reproduction by doubling the usage time of the tape.
