Abstract

PURPOSE:To obtain a head switching signal with a simple constitution, by providing a head exclusive by used for special reproduction like still reproduction and preventing the distortion of a servo system through the use of the head. CONSTITUTION:The 1st, 2nd heads 11, 12 for normal reproduction at the location of 180 deg. on a rotating head base 10, the 3rd, 4th for double speed or still reproduction orthogonally on the heads 11, 12 are located to constitute a rotating head device and a rotating detector 20 having a pair of detection coils is coupled to the device. A detection pulse detected at a detection coil of the device 20 is inputted to a switching pulse generating circuit 21, the output of the circuit 21 is taken as high level, the operating period of the head 2 is taken as low level and inputted directly to a rotating head device 22. The output of the circuit 21 is inputted to a monostable multivibrator circuit 23 and a terminal D of a D type FF circuit 25, the output of the circuit 25 is given to a head switching circuit 26 to output the head switching signal without distortion of a servo system of the device 22.
