<p>PROBLEM TO BE SOLVED: To obtain a drum device for magnetic recording/reproducing which does not affect power source supply ability, is strong in noises and has no problems such as a timing deviation when a pulse control signal for changing a reproducing head channel is transmitted from a fixed drum section to a rotary drum section. SOLUTION: This device is provided with a timing signal generating means for generating a timing signal according to the rotation of a rotary drum section, a timing signal transmitting means provided and spread over the rotary drum section 10 and a fixed drum section 12 to transmit the timing signal from the fixed drum section 12 to the rotary drum section 10 over the specified rotational rangeθof the rotary drum section 10, a head changing signal generating circuit section 22 provided in the rotary drum section 12 to generate a head changing signal according to the timing signal. Thus, a magnetic recording/ reproducing drum device having no problems such as a timing deviation is obtained.</p> |
