Magnetic recording/reproducing apparatus having a locus plane of rotary heads tiltable with respect to a lower drum

A magnetic recording/reproducing apparatus including drum means provided with rotary head means for recording and reproducing signals on and from slant tracks on a magnetic tape threaded around a periphery of said drum means, said drum means having a contact portion extending along said periphery in a predetermined angular range, said contact portion making a slide contact with the magnetic tape threaded around said drum means, said drum means having an upper drum and a lower drum, said lower drum being comprised of a lead portion for guiding a reference edge of said magnetic tape, said magnetic recording/reproducing apparatus comprising:

• pivot means for pivoting said rotary head means, said pivot means provided on a straight line extending orthogonal to a central axis of said lower drum and approximately bisecting said predetermined angular range and further residing within a vicinity of a locus plane of said rotary head means, said pivot means provided in a proximity of said locus plane of said rotary head means;
• and
• tilting means for causing said locus plane of said rotary head means to tilt with respect to said lower drum and around said straight line by a predetermined angle.
