Abstract: A recording and/or reproducing apparatus for recording and/or reproducing digital audio signal on a recording medium such as a magnetic tape, which includes a recording and/or reproducing unit, an analog-to-digital convertor, a decimation filter, and noise shaper. The recording and/or reproducing unit records and/or reproduces signal on a recording medium at a speed double relative moving speed of a head and the recording medium at least. The analog-to-digital convertor converts input analog audio signal into digital signal with a sampling frequency which is above the audio frequency band, and sufficiently higher than the maximum frequency capable of recording by the recording and/or reproducing unit. The decimation filter reduces the sampling frequency of the digital signal output from the analog-to-digital convertor, and converts it into digital signal of m-bit (m > n). The noise shaper converts the digital signal from the decimation filter from m-bit to n-bit, and then in requantizing, shapes noise so as to suppress within the audio frequency band, and supplies it to the recording and/or reproducing unit.

Abstract: A recording and/or reproducing apparatus divides long bit-length data into upper bit data and lower bit data, and record both data along with discriminating data in a manner that the upper-bit data and the lower-bit data are allocated and recorded, on an alternating basis, onto the scan start side areas and the scan end side areas of a plurality of pairs of recording tracks, in order to obtain more high-quality digital audio signal to be recorded and reproduced.

Abstract: A tracking control circuit of a rotary head tape magnetic recording and reproducing apparatus. The tracking control circuit generates (16) sampling pulses of first and second pilot signals for tracking based on a synchronization signal for tracking on a recording track, detects (12) an envelope signal from the reproduction signal reproduced by the magnetic heads (22A, 22B) which is amplified with a predetermined gain, detects (47) tracking error data from first and second pilot data obtained by sampling the envelope signal with the sampling pulses, detects (48, 55) reproduction level error data, controls (19C) the feeding speed of the magnetic tape based on the tracking error data, and controls (57, 58) the amplifying gain of the reproduction signal based on the reproduction level error data. As a result, deviations of reproduction levels of the magnetic heads (22A, 22B) are effectively corrected, and tracking control of the magnetic heads on the recording tracks is extremely precise.
