发明名称 TAPE TRAVELING SPEED SETTING DEVICE FOR MAGNETIC RECORDING AND REPRODUCING DEVICE
摘要 <p>PURPOSE:To correctly discriminate traveling speed at the time of a recording by different n-1 types of reference values set beforehand and to set it as reproducing speed by providing a reference period setting means to set a reference period in accordance with the reproducing speed, a specific traveling speed setting means, etc. CONSTITUTION:When the traveling speed of a tape 1 is detected and the tape traveling speed is equal to the set value of the reproducing speed and constant, the period of a reproducing control signal detected by a period detecting means 9 is compared with the reference period set by a reference period setting means 12, the tape traveling speed at the time of the recording is discriminated and the result is set as the reproducing speed. When the tape traveling speed is not constant, the discrimination of the tape traveling speed at the time of the recording is not executed and an initial value or a previous discrimination result is held. Thus, when (n) types [the (n) is a natural number] of the tape traveling speeds exist, the traveling speed at the time of the recording is correctly discriminated by the different n-1 types of reference values set beforehand and can be set as the reproducing speed.</p>
