Magnetic recording/reproducing apparatus with independently tiltable head drum and tape lead guide

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 upper and lower drums and a contact portion, said contact portion being provided on each of said upper and lower drums on adjacent sections thereof, said 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 upper drum carrying said rotary head means, and said magnetic recording/reproducing apparatus comprising:

• a stepped portion formed as a part of said lower drum at a lower portion thereof, a diameter of said stepped portion being smaller than that of said contact portion of said lower drum;
• a lead portion provided separately from said drum means for guiding a reference edge of said magnetic tape, said lead portion forming a rim portion having a diameter larger than that of said contact portion provided on said lower drum, with said rim potion being loosely fitted on said stepped portion so as to allow said rim portion to move independently from said lower drum;
• first tilting means for tilting, by a predetermined angle, said drum means including said rotary head means about a first straight line extending orthogonal to a center axis of said lower drum;
• and
• second tilting means for tilting said lead portion independently from a tilt of said drum means about a second straight line parallel to said first straight line by a predetermined angle.
