Abstract: An apparatus for recording and/or reproducing digital signals, such as PCM signals, as plural slanted tracks on a magnetic tape, includes a memory, first and second heads, a detection unit and a control unit. The memory stores the digital signals entering a terminal. The first head records the digital signals entering the terminal along with input address information. The second head is positioned on the downstream side of the first head in the running direction of the magnetic tape. The second head reads out the digital signals recorded on the magnetic tape by the first head along with the address information. The detection unit detects whether or not there is any error in the signal read out by the second head.

Abstract: In a recording and/or reproducing apparatus, a recording medium is reproduced for a predetermined period of time when it is detected by sequentially searching the record medium that date information recorded on the recording medium has changed at least a predetermined amount. A scan reproduction may be achieved in the form of information units, information units being different in point of recording time from each other.

Abstract: In a recording apparatus having a digital signal input which can record such digital signal on a recording medium, when a condition of the input signal changes during the recording operation the recording apparatus is automatically set into a recording pause mode and such operating mode is indicated to the operator. When the condition of the input signal is stabilized within a predetermined period of time during such recording pause mode, the recording medium is automatically rewound and the recording apparatus is then released from the recording pause mode and recording commences at a location on the record medium so as to record over any previously recorded unstable signal.

Abstract: An apparatus for recording a program number on a recording medium arranged so that after its operation mode is changed into the recording standby mode, a desired program number can be selected by means of one or more keys and the selected program number is recorded at each program when the recording is started.

Abstract: An apparatus for recording and/or reproducing a control signal in which a start point from which a control signal such as a program start identifying signal is recorded in a sub-code area is set by the use of an address signal written in a PCM area so that the positional information of a recording medium can be exactly detected and thereby it is assured that the control signal can be recorded in a desired position.

Abstract: A record player is equipped with a tonearm control which enables the record player to perform an automatic music search, that is, the pickup device of the tone arm may be automatically controlled to be set down at the beginning of a selected song. It may happen that the center of the record is slightly displaced from the center of the turntable, so that different angular segments of the recorded tracks lie at different radial distances from the turntable center. The present tonearm control compensates for this by detecting the radial and angular position of the beginning of the selected song and by setting down the pickup device at this position. The radial position of the beginning of each song is measured along a radial reference detection line while the turntable is at rest at an initial angular position. Then, while the turntable is rotating, the tone arm is moved across the record until the pickup device reaches the measured radial position of the beginning of the selected song.
