ABSTRACT:
A position determining mechanism for a magnetic head utilizes a plurality of steps of varying thickness formed on a rotatable disk to set the position of a magnetic head, e.g. in relation to tracks of a magnetic tape. Steps of the disk are selectively positioned between a member attached to the magnetic head and a fixed position reference surface, with the disk being normally held pressed between the magnetic head mounting member and the reference surface by a spring and being made free to rotate when the magnetic head mounting member is pulled apart from the position reference surface by a solenoid, to enable the disk to be rotated to select a step of different thickness for determining a different position of the magnetic head.
