Feeding device for a magnetic head

An apparatus for recording information on a circular recording area on a rotatable recording medium and/or reproducing the information from said recording area, comprising:

• a head member provided in opposed relationship with said recording medium;
• pivoting means having a pivot axis and pivoting about said pivot axis;
• driving means for pivoting said pivoting means;
• a support member holding said head member and movable in a rectilinear direction on a straight line passing through the center of rotation of said recording medium;
• and
• means for coupling said pivoting means and said support member at a contact position spaced apart from said pivot axis by a predetermined distance, said coupling means converting the pivotal displacement of said pivoting means into rectilinear displacement of said support member, and said coupling means being provided so that when said head member is opposed to a substantially intermediate position between outermost and innermost peripheral positions of said circular recording area, a segment passing through said contact position and the center of curvature of a path of movement of said contact position is orthogonal to said straight line.

• a head member provided in opposed relationship with said recording medium;
• pivoting means having a pivot axis and a contact member spaced apart from said pivot axis by a predetermined distance, and pivoting about said pivot axis;
• driving means for pivoting said pivoting means;
• a support member holding said head member and movable in a rectilinear direction on a straight line passing through the center of rotation of said recording medium, and having a flat surface intersecting at a substantially right angle to said straight line;
• and
• means for coupling said contact member of said pivoting means and said flat surface of said support member to convert the pivotal displacement of said pivoting means into rectilinear displacement of said support member, said coupling means being provided so that said contact member slides on said flat surface during said pivotal displacement of said pivoting means.
