ABSTRACT:
A recording/reproducing apparatus in which recording/reproducing characteristics for the magnetic tape may be stabilized and data errors may be reliably prevented form occurrence. The recording/reproducing apparatus has a magnetic head 81 in which a pair of magnetic core halves 83A, 83B of a magnetic material are abutted to each other via a gap material g to form a magnetic core. Magnetic tape guide units 82A, 82B are provided in the vicinity of the magnetic head 81. The magnetic tape guide units 82A, 82B are formed with magnetic tape suction openings 82b, 82b closed by a magnetic tape 88 adapted for having a sliding contact with the tape slide surface 82a. The magnetic tape suction openings 82b, 82b suck the magnetic tape 88 running on the tape slide surfaces 82a, 82a of the magnetic tape guide units 82A, 82B.
