Abstract:
A recording/reproducing apparatus comprising:transmission/reception means of transmitting/receiving data and command signals from a transmission line, the command signals including an operation valid/invalid command received from a control apparatus by way of the transmission line; recording/reproducing means of recording data received from said transmission/reception means on a recording medium during reception and of transmitting data reproduced from said recording medium to said transmission/reception means during transmission; operation means of generating an operation signal for determining the operation of said recording/reproducing means; control means of controlling said recording/reproducing means in accordance with said command signals or said operation signal; and switching signal generation means of outputting a switching signal for determining whether said operation signal is valid or invalid to said control means; wherein the transmission/reception means is configured to provide the operation valid/invalid command to the switching signal generation means; the switching signal generation means is configured to output the switching signal in response to the operation valid/invalid command received from the control apparatus; said switching signal generation means outputs said switching signal as an operation means valid signal for validating said operation signal to said control means in the case when a command received from said transmission/reception means is an operation valid command, and said switching signal generation means outputs said switching signal as an operation means invalid signal for invalidating said operation signal to said control means in the case when a command received from said transmission/reception means is an operation invalid command, and said control means validates said operation signal output from said operation means and disregards said command signal in the case of receiving said operation means valid signal, and said control means invalidates said operation signal output from said operation means and uses said command signal in the case of receiving said operation means invalid signal.
