Abstract
A recording apparatus has a plurality of erasing heads arrayed aslant to the direction in which a strip-like recording medium is to be transported. An erasing operation on recorded information on the recording medium obliquely begins and obliquely ends by switching the erasing heads on and off one after another along an oblique recording track on the recording medium to accomplish information editing without introducing noises.
Claims8
An information signal recording apparatus, comprising:
- (a) recording means including at least one rotating head which traces a tape-shaped recording medium obliquely in the lengthwise direction of said medium for recording the information signal on said medium;
- (b) erasing means including n-pieces (wherein n is an integer of two or larger) of fixed erasing heads for tracing different positions in the direction of the width of said tape-shaped recording medium in the lengthwise direction of the same, wherein each of said fixed erasing heads includes a gap which extends obliquely to said medium and substantially matches the direction in which said rotating head traces said medium;
- and
- control means for individually controlling the erasing operations of said n-pieces of fixed heads.
An information signal recording apparatus, comprising:
- (a) recording meand including at least one rotating head which traces a tape-shaped recording medium obliquely in the lengthwise direction of the same for recording the information signal on said medium;
- (b) erasing means including n-pieces (wherein n is an integer of 2 or larger) of fixed erasing heads tracing different positions in the direction of the width of said tape-shaped recording medium in the lengthwise direction of the same, all of said n-pieces of fixed erasing heads being arranged so that the traced loci respectively traced by a pair of fixed heads adjoining each other in the direction of the width of said tape-shaped recording medium will be partially overlapped;
- and
- (c) control means for individually controlling the erasing operations of said n-pieces of fixed heads.
An information signal recording apparatus, comprising:
- (a) a cylindrical member having formed in the outer peripheral surface thereof a guide portion for guiding a tape-shaped record bearing medium;
- (b) a recording heat rotatable relative to said cylindrical member for recording information signals on the tape-shaped record bearing medium as guided by said outer peripheral surface;
- and
- (c) an erase head fixedly secured to said cylindrical member to erase the signal recorded on the tape-shaped record bearing medium on the outer peripheral surface of said cylindrical member.
