Abstract

PURPOSE:To make an accurate scan on a recording track by equipping a rotary magnetic head on a bimorph cell with electro-strictive effect and by limiting the height position of a magnetic head in a contactless period of a magnetic tape. CONSTITUTION:Magnetic tape 28 runs around head cylinder 30. Head 31 is fixed to the head cylinder thrugh piezoelectric-element bimorph cell 32, but in case of a two- head system, one head is free while the other head is in operation of recording a signal on the magnetic tape. To the head in no contact with this magnetic tape, head positioning head 33 is provided closely and a signal is transferred from oscillator 36 through amplifier 37 to provide a magnetic field. Bimorph element 32B vibrates mechanically magnetic head 31B and its head signal is supplied to bimorph driver circuit 40B to detect the position by magnetic head 31B, so that accurate tracking will be carried out.
