Abstract

PURPOSE:To accurately display the feed quantity of a magnetic tape at the time of reproduction by reading out a numeric string of binary number written on the tape and numeric data of four digits of binary coded decimal written at either before or behind, or before and behind of the numeric string at the time of recording, and displaying the feed quantity of the tape at the time of reproduction. CONSTITUTION:When the count value of a tape feed quantity counter 3 to count the feed quantity of the magnetic tape 5 in units of hour, minute, and second by counting a CTL pulse arrives at a prescribed value, the numeric data of four digits of binary coded decimal is written either before or behind, or before and behind of the binary numeric string decided in advance on the magnetic tape 5. And the preset of the tape feed quantity counter 3 is performed by reading out those numeric string and numeral by the duty detector 8 of the CTL pulse at the time of reproduction. In such a way, it is possible to display the feed quantity of the tape at the time of reproduction in the feed quantity of the tape at the time of recording accurately.
