Abstract
Abstract A helical scanning type magnetic recording and reproducing apparatus records a signal representing recording conditions on a magnetic tape when a recording is effected thereon, together with a PCM audio signal. At the time of reproduction, reproducing conditions are controlled so as to be the same as the recording conditions on the basis of the signal representing recording conditions reproduced.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
199 words
A digital information recording and reproducing apparatus having a magnetic head which records a signal to be recorded on a magnetic tape so that a recording track which is inclined at a predetermined angle with respect to the traveling direction of said magnetic tape is formed, audio signal processor means for converting an audio signal to be recorded into a digital signal, and gate means for supplying said digitized audio signal to said magnetic head so that said digitized audio signal is recorded in a desired one of a plurality of regions obtained by dividing said recording track, said apparatus comprising: means for generating a signal representing conditions set at the time of recording; means for discriminating the recording conditions from the signal representing the recording conditions during reproduction; and control means for setting conditions at the time of reproduction on the basis of the discriminated recording conditions, at the time of recording, the signal representing recording conditions being recorded on the magnetic tape together with said digitized audio signal, and at the time of reproduction, reproducing conditions being set such as to be the same as the recording conditions in accordance with the signal representing recording conditions reproduced.
Claim 2
Dependent Claim
199 words
A digital information recording and reproducing apparatus having a magnetic head which records a signal to be recorded on a magnetic tape so that a recording track which is inclined at a predetermined angle with respect to the traveling direction of said magnetic tape is formed, audio signal processor means for converting an audio signal to be recorded into a digital signal, and gate means for supplying said digitized audio signal to said magnetic head so that said digitized audio signal is recorded in a desired one of a plurality of regions obtained by dividing said recording track, said apparatus comprising: means for generating a signal representing conditions set at the time of recording; means for discriminating the recording conditions from the signal representing the recording conditions during reproduction; and control means for setting conditions at the time of reproduction on the basis of the discriminated recording conditions, at the time of recording, the signal representing recording conditions being recorded on the magnetic tape together with said digitized audio signal, and at the time of reproduction, reproducing conditions being set such as to be the same as the recording conditions in accordance with the signal representing recording conditions reproduced.
Claim 3
Dependent Claim
55 words
A digital information recording and reproducing apparatus according to Claim 1, wherein said signal representing recording conditions represents at least one of the recording conditions, such as the traveling direction of the magnetic tape, either the standard play or long play mode, either the video signal recording or multichannel PCM method, and automatic reverse recording.
Claim 4
Dependent Claim
30 words
A digital information recording and reproducing apparatus according to Claim 1, further comprising display means for displaying the recording conditions on the basis of said signal representing recording conditions reproduced.
Claim 5
Dependent Claim
40 words
A digital information recording and reproducing apparatus according to Claim 1, further comprising means for generating a character signal representing recording conditions on the basis of said signal representing recording conditions reproduced, and display means for displaying said character signal.
Claim 6
Dependent Claim
34 words
A digital information recording and reproducing apparatus according to Claim 1, further comprising means for determining whether a recording on a magnetic tape has been effected by the NTSC system or the CCIR system.
