Abstract
A data recording apparatus records data onto a recording medium having a flash memory in which data can be written in block units using a part of a recording region as an alternative block for a defect block in which normal data writing cannot be performed. The data recording apparatus causes a user to select one of plural recording modes including a first recording mode and a second recording mode in which an amount of data to be processed is larger than that of the first recording mode, then obtains data in the selected recording mode and stores the data onto the recording medium. If an alternative block remaining amount obtained from the recording medium is equal to or less than a threshold value, the data recording apparatus allows recording in the first recording mode and inhibits recording in the second recording mode.
