ABSTRACT:
The invention relates to a method and to apparatus for quickly and accurately positioning the rotary magnetic heads of a recorder/reader unit. The support for the magnetic heads includes a turntable and a countertable that are circular and that have a common axis of rotation, each including a peripheral support zone and a central support zone. The magnetic heads are situated around the periphery of the turntable. A screw enables the peripheral support zones to be brought into contact with each other and then the central support surfaces to be brought into contact with each other. The invention is applicable to recording and/or reading information on a magnetic tape.
