Digital recording/reproducing apparatus |
摘要 |
A digital recording apparatus has a transporter and processor. (1). Long play mode: The transporter rotates heads and transports a recording medium at each first speed. The processor converts a first input signal supplied at a normal transfer speed with A/D conversion at a first sampling frequency to generate a first data of a quantization levels, converts the first data to a second data of a quantization levels with a first clock frequency and processes the second data which is supplied to the heads so as to be recorded in the medium. (2). High recording mode: The transporter rotates the heads and transports the medium at each second speed which is N times faster than the first. The processor has a converter to convert a second input signal supplied at a transfer speed which is N times faster than the normal to a third signal having a second sampling frequency which is N times higher than the first and to process the third signal with a second clock frequency which is N times higher than the first to supply the third signal to the heads so as to record the third signal in the medium.
