Abstract
A disk device is arranged to select an appropriate rotation control method according to a kind of an optical disk, a recording format or a recording method so that a recording operation for a certain amount of information may be completed as fast as possible, even if a waiting time takes place until the rotation is set. The disk device includes a unit for selecting the rotation control method for recording a certain amount of information more efficiently and rapidly in light of time according to a kind of an optical disk, a recording format or a recording method. The selected rotation control method is executed to control the rotation of the optical disk when recording information on the disk.
Claims9
A disk device comprising:
- recording and reproducing means for optically recording information including image and voice on a disk-like recording medium or reproducing information from said disk-like recording medium;
- and
- rotation control selecting means for selecting a method of rotating said disk-like recording medium according to a recording format with which said information is recorded on said disk-like recording medium.
A disk device comprising:
- recording means for optically recording plural kinds of information on a disk-like recording medium with rotating said recording medium;
- and
- rotation control selecting means for selecting a method of rotating said disk-like recording medium according to a recording format defined by a kind of information to be recorded.
An information recording apparatus comprising:
- information input means for being supplied with plural kinds of information, each of which has a recording format having been defined in advance;
- recording means for recording said information inputted in said information input means on a disk-like recording medium with rotating said disk-like recording medium;
- discriminating means for discriminating the recording format of said information to be inputted by said information input means and to be recorded on said disk-like recording medium;
- and
- control means for controlling said recording means in a manner to change a recording operation of said recording means between a first recording operation and a second recording operation on the basis of said recording format discriminated by said discriminating means.
An information recording method comprising the steps of:
- detecting a kind of a disk-like rotating recording medium;
- setting an information recording format according to said detected kind of medium;
- selecting a rotation control method corresponding with said set format;
- and
- recording information on said disk-like rotating recording medium as rotating said recording medium through the effect of said selected rotation control method.
