发明名称 Video signal recording apparatus.
摘要 <p>A video signal recording apparatus comprises a tape guide drum (1) around which a magnetic tape (2) is to be wrapped and a first and a second rotary head (5A, 5B) arranged alternately to come into contact with the tape (2), the extending directions of transducing gaps of the heads (5A, 5B) being different from each other, and the initial time when the heads (5A, 5B) respectively come into contact with the tape (2) being synchronized with a vertical sync signal of a recording signal to be supplied from a camera (10, 20), thereby recording the recording signal on the tape (2). When the wrap angle of the tape (2) around the drum (1) is 0 the wrap angle θ is selected so that:where M and M' are integers, and when the expression with respect to the wrap angle ε equals M, an angular distance a between the gaps of the heads (5A, 5B) is selected so as to cause a time difference of (m + 0.5)T, where m is an integer and T is a time corresponding to one horizontal period, and when the expression equals M' + 0.5, said angular distance a is selected so as to cause a time difference of mT.</p>
