Abstract
A bi-directional tape recorder wherein abrasion of portions of a magnetic head on the opposite sides of the air gap is reduced and 'soil' sticking to a tape contacting face of the magnetic head is automatically removed to attain elongation of the life of the magnetic head. The magnetic head is changed over between a pair of positions inclined with respect to a fixed axis perpendicular to the tape feeding direction by a shiftable member which is shifted in one or the other direction in response to reversing operation of the tape feeding direction. The magnetic head is connected to be moved in a widthwise direction of a magnetic tape by the shiftable member to allow reproduction of a pair of regenerative tracks of the magnetic tape. A pair of azimuth adjusting mechanisms are provided on the opposite sides of the magnetic head for making azimuth adjustment of the magnetic head independently of each other, and one of them is associated with the shiftable member.
