Abstract

Partial information such as the beginning data of each of chapters is read from a CD and written in a HDD 10 at a higher speed than that in a normal reproduction while the normal reproduction is carried out using a buffer memory 8. After the chapters relative to all CDs have been written in the HDD 10, reproduction is carried out in switching between the information remaining in the HDD 10 and the information included in the CD. This configuration makes it unnecessary to record the information beforehand, and permits an unreproduciable blank in reproduction to be filled with audio information during track search or CD change while the reproduction is carried out normally.

Claims

1. A recording/reproducing apparatus comprising:

storage means for storing information read from a recording medium on which the information is written in a prescribed number of groups;

means for reading the information on said recording medium; and

control means for controlling the write in said storage means of at least a prescribed time of information corresponding to a beginning address of each of said groups.

2. A recording/reproducing apparatus according to

claim 1

, wherein said means for reading reads the information on said recording medium at a speed of N-times as high as a normal speed.

3. A recording/reproducing apparatus according to

claim 1

, wherein said control means controls the write of the information read from said recording medium while it controls reproduction of the information written in said storage means at any time.

4. A recording/reproducing apparatus according to

claim 3

, wherein said control means causes a prescribed time of information of the information written in said storage means to be held therein and the other information to be discarded after reproduction.

5. A recording/reproducing apparatus according to

claim 1

, wherein said control means correlatively manages said prescribed time of information written in said storage means and the recording medium in which it has been written.

6. A recording/reproducing apparatus according to

claim 5

, further comprising:

means for detecting identification information for identifying said recording medium, wherein where said prescribed time of information contained in the recording medium identified by said identifying means has been already written in said storage means, said control means inhibits storage of the information into said storage means.

7. A recording/reproducing apparatus according to

claim 1

, further comprising:

a holding member for holding a plurality of recording media, wherein

said control means causes said storage means to store said prescribed time of information relative to all said recording media held in said holding member.

8. A recording/reproducing apparatus according to

claim 7

, wherein after said control means causes said storage means to store said prescribed time of information relative to all said recording media held in said holding member, it continues reproduction using the information remaining in said storage means.

9. A recording/reproducing apparatus according to

claim 7

, wherein after said control means causes said storage means to store said prescribed time of information relative to all said recording media held in said holding portion, it continues reproduction using the information recording in said recording media.

10. A recording/reproducing apparatus according to

claim 1

, wherein said recording means is a compact disk and said storage means is a hard disk drive.
