Image data recording apparatus and method

An image data recording apparatus, comprising:

• a recording medium information acquiring unit configured to acquire information regarding free space on a recording medium;
• a classifying unit configured to classify the free space into a plurality of classes according to a writing speed;
• and
• a recording unit configured to record image data in the free space on the recording medium on the basis of an image quality mode set for the image data to be recorded and the class classified by the classifying unit, wherein
• the image data includes movie data, and
• when there are a plurality of classes having the writing speed matching the image quality mode of the movie data, the recording unit records the movie data in each of the free spaces so that the classes of the writing speed are arranged in an order from slow to high.

An image data recording method utilized in an image data recording apparatus, the method comprising:

• acquiring information regarding free space on a recording medium;
• classifying the free space into a plurality of classes according to a writing speed;
• and
• recording image data in the free space on the recording medium on the basis of a bit rate of the image data to be recorded and the class classified in the classifying step, wherein
• the image data includes movie data, and
• when there are a plurality of classes having the writing speed matching the bit rate of the movie data, the recording includes recording the movie data in each of the free spaces so that the classes of the writing speed are arranged in an order from slow to high.

• computer-executable instructions for recording image data in the free space on the recording medium on the basis of one of an image quality mode set for the image data to be recorded, a bit rate of the image data to be recorded, and the class classified in the classifying step, wherein
• the image data includes movie data, and
• when there are a plurality of classes having the writing speed matching one of the bit rate and the image quality mode of the movie data, the recording includes recording the movie data in each of the free spaces so that the classes of the writing speed are arranged in an order from slow to high.

An image data recording apparatus, comprising:

• a recording medium information acquiring unit configured to acquire information regarding free space on a recording medium and information regarding a writing speed of the free speed;
• a determining unit configured to determine recording position on the recording medium on the basis of the information and a bit rate of the image data to be recorded;
• and
• a recording unit configured to record image data at the determined recording position on the recording medium, wherein
• the image data includes movie data, and
• when there are a plurality of free spaces having the writing speed matching the bit rate of the movie data, the determining unit determines the recording position in each of the free spaces so that the classes of the writing speed are arranged in an order from slow to high.
