Abstract

A reproducing apparatus for detecting and storing information about the presence or absence of information in each recording track of a recording medium. A scanning head is first moved to the recording track which is in a position opposite the the recording track in which the reproduction will be initiated. Then the scanning head successively processes each recording track to determine the presence or absence of information. Upon termination of the processing of each recording track, the scanning head is located at the recording track in which the reproduction will be initiated. Display is made of the number of consecutive blank tracks.

Claims

1. A recording and/or reproducing apparatus for recording or reproducing image information in or from each of recording blocks provided on a recording medium, comprising:

a) switching means for switching a recording mode between a single recording mode and a continuous recording mode;

b) first detecting means for detecting the number of pictures continuously recordable, the number of unrecorded blocks not corresponding to the number of pictures continuously recordable on the recording medium;

c) first display means for displaying information on the number of pictures continuously recordable on to the recording medium which has been detected by said first detecting means;

d) control means which is arranged to cause said first display means to display the amount of pictures continuously recordable on the recording medium when the switching mode is switched to said continuous recording mode by said switching means; and

e) second display means for displaying that the recording mode is the continuous recording mode when the recording mode is switched to the continuous recording mode by said switching means.

2. An apparatus according to claim 1, further comprising:

d) a head arranged to record or reproduce information in or from each of said blocks.

3. An apparatus according to claim 2, further comprising:

e) second detecting means for detecting the address of a recording block to which said head is having access.

4. An apparatus according to claim 1, wherein said recording medium is in a disc-like shape.

5. An apparatus according to claim 4, wherein said recording blocks are recording tracks concentrically formed on said disc-shaped recording medium.

6. An apparatus according to claim 1, wherein said first detecting means includes:

a) detecting means for detecting the presence or absence of any existing recording in each of said blocks; and

b) counting means for counting the number of blocks which are found to have no existing record therein.

7. A recording apparatus for recording image information in recording blocks provided on a recording medium, comprising:

switching means for switching a recording mode between a single recording mode and a continuous recording mode;

detecting means for detecting a number of pictures continuously recordable on said recording medium, the number of unrecording blocks not corresponding to the pictures continuously recordable on the recording medium; and

means for displaying the number of pictures continuously recordable when said switching means is switched to said continuous recording mode.

8. A recording apparatus according to claim 7, wherein said display means includes seven-segment display element.

9. A recording apparatus according to claim 7, wherein said recording medium is a disc-shaped recording medium.

10. A recording apparatus according to claim 9, wherein said recording blocks are recording tracks concentrically formed on said recording medium.
