Abstract
In a disk apparatus capable of quickly recording a certain amount of information without waiting until a rotation is stabilized, a rotation control method is selected based upon the sort of optical disk, the recording format, the recording method, and the like for quickly recording a certain amount of information in a higher efficiency in view of a temporal aspect. Then, the disk apparatus records information on the optical disk, while the disk apparatus controls a rotation of the optical disk in accordance with the selected rotation control method.
Claims10
A disk apparatus comprising:
- recording/reproducing means for optically recording information including image and/or voice on an exchangeable disk-type recording medium, or for optically reproducing information from said exchangeable disk-type recording medium;
- and
- rotation control selecting means capable of selecting and changing a sort and a method of rotation control operation of said disk-type recording medium,
- wherein, when first process operation for recording or reproducing said information on said disk-type recording medium and second process operation for recording or reproducing said information on different area from where said first process operation is being made are carried out in parallel, said rotation control selecting means selects the sort of the rotation control operation for said disk-type recording medium in said first process operation in conjunction with said second process operation.
A disk recording/reproducing method in a disk apparatus equipped with recording/reproducing means for optically recording information including image and/or voice on an exchangeable disk-type recording medium, or for optically reproducing information from said exchangeable disk-type recording medium, comprising the steps of:
- providing said disk apparatus with rotation control selecting means capable of selecting and changing a sort and a method of rotation control operation of an optical disk;
- performing a first process operation for recording said information on a first area of said disk-type recording medium, or for reproducing said information from a first area of said disk-type recording medium;
- and
- performing a second process operation for recording on a second area of said disk-type recording medium, the second area being different from the first area, or for reproducing from the second area in parallel with said first process operation;
- selecting the sort of the rotation control operation for said disk-type recording medium in said first process operation in conjunction with said second process operation by said rotation control selecting means.
A disk apparatus comprising:
- recording/reproducing means for recording information on an exchangeable disk-type recording medium, or reproducing information from said disk-type recording medium;
- and
- rotation control selecting means capable of selecting, or changing either a sort or a method of a rotation control operation of said disk-type recording medium,
- wherein said recording/reproducing means performs;
- a first process operation for recording said information on a first area of said disk-type recording medium, or for reproducing said information from a first area of said disk-type recording medium;
- and
- a second process operation for recording said information on a second area of said disk-type recording medium or for reproducing said information from a second area in parallel with said first process operation, the second area being different from the first area,
- and wherein said rotation control selecting means selects either a sort or a method of rotation control operation for said disk type recording medium in said first process operation in conjunction with said second process operation.
A disk apparatus comprising:
- reproducing means for reproducing information from an exchangeable disk-type recording medium;
- and
- rotation control selecting means capable of selecting, or changing either a sort or a method of rotation control operation of a disk,
- wherein said reproducing means performs;
- a first process operation for reproducing said information from a first area of said disk-type recording medium;
- and
- a second process operation for reproducing said information from a second area of said disk-type recording medium, the second area being different from the first area, in parallel with said first process operation;
- wherein said rotation control selecting means selects either a sort or a method of rotation control operation for said disk-type recording medium in said first process operation in conjunction with said second process operation.
