PURPOSE:To obtain a recording and reproducing system circuit having a stable characteristic by contituting directly a circuit of a recording and reproducing system, on an arm. CONSTITUTION:A magnetic head 16 is held by an arm 14, and the other end of the arm 14 is fixed to a carriage 13 by a connector 11. Electronic parts 12 such as an integrated circuit chip are attached onto the arm 14 by using the body of the arm 14 as a substrate, and a recording and reproducing circuit is formed instead of a recording and reproducing system circuit 6. A circuit pattern formed on the arm 14 by a thin film having a high conductivity is led to the connector 11 for coupling the arm 14 and the carriage 13, and an input and an output of a signal are executed. The connector 11 inputs and outputs a signal, and also executes a mechanical function for fixing the arm 14 to the carriage 13. |
