Abstract
An image signal recording and reproducing apparatus comprises a head array having a plurality of head gaps for recording and reproducing the image; a piezoelectric actuator having a polarization direction and for moving the head array downwards and upwards in a width direction of a track in accordance with input of a driving voltage; a phase comparator for generating a phase control signal in accordance with a phase difference between the head array and the track; a unit for outputting the driving voltage to the actuator in accordance with the phase control signal; and a signal processing unit for recording and reproducing the image signal on and from the track by the head array.
Claims9
An apparatus for recording and reproducing an image signal on and from tracks of a tape, said apparatus comprising:
- a head array having blocks of a plurality of head gaps which are arranged in a stepwise manner and having an inclination with a predetermined angle to the tape;
- a servo control means for moving said head array downwards and upwards so as to scan said tape, said servo control means having an actuator attached to said head array, a phase comparator for comparing a phase between said head array and said tracks of said tape to produce a comparison result and a piezo driving means for supplying a driving voltage to said actuator in accordance with the comparison result, said actuator reciprocating said head array upwards and downwards periodically;
- and
- a signal processing apparatus for recording said image signal on said tracks of said tape by said head array and reproducing said image signal from said tracks of said tape in which said image signal is recorded.
