<p>PURPOSE:To rapidly search a program of music by including a head for repro ducing a PCM signal at a fixed position on a magnetic tape during a high speed running and a moving means for moving the head vertically with respect to a tape running direction according to a drive means in a device for reproduc ing a recording signal using a rotary head. CONSTITUTION:An aperture is provided on a head cover 604 or protecting a magnetic tape and stabilizing a tape running and a reproducing head 601 is vertically movably inserted thereinto. The head 601 fixes one end part of a piezoelectric element 602 made of a piezoelectric element and fixes the other end part to a column. Constituting in such a way, to the fixed side of the piezoelectric element 602, a drive signal is impressed and a reproducing signal is taken out from the head 601. When the tape runs at high speed, if this is a forward feeding, the drive signal shown in the figure (a) is supported, and if this is a backward feeding, the drive signal shown in the figure (b) is applied to produce a desired operation in the head 601. In this manner, signals of a music head and a middle of a music and a time code or the like can be efficiently reproduced.</p> |
