ABSTRACT:
An apparatus for recording information on concentric circular recording tracks on a rotatable magnetic recording medium and/or reproducing the information from the recording tracks comprises a magnetic head provided in opposed relationship with the recording medium, a rotatable member, a driving device for intermittently rotating the rotatable member by a predetermined angle, a lever having a pivot shaft and intermittently pivoting in a predetermined direction about the pivot shaft by a unit pivot angle corresponding to the predetermined angle in response to the rotatable member, and a mechanism for intermittently moving the magnetic head in one direction on a straight line passing through the center of rotation of the recording medium in response to the pivoting lever, the head moving mechanism converting the pivotal displacement of the pivoting lever into rectilinear displacement.
