ABSTRACT:
A head feeding mechanism in a magnetic recording and reproducing device comprises: a "0" side carriage which has a "0" side magnetic head mounted on the surface of the front end portion thereof, and is fed in the direction of length of a slot formed in a magnetic disk holder, into which a magnetic disk is loaded, by a guide provided on a device frame; and a "1" side carriage which has a "1" side magnetic head 16 mounted on the surface thereof which is confronted with the "0" side magnetic head, and a base which is flexibly supported on the base 1a of the "0" side carriage, and driven ears extended from the middle portion thereof which are driven by the edge of the slot with the aid of an energizing spring. In the mechanism, the "0" side carriage is formed rigid by molding resin, and has a flexible thin portion in the middle of the front end portion thereof which is much smaller in thickness than the other portions, and the "0" side magnetic head is soldered to a flexible printed circuit board with the flexible thin portion held between the "0" side magnetic head and the flexible printed circuit board.
