DATA RECORDER AND DATA RECORDING METHOD, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To continue recording even when a vacant capacity is not present in a recording medium. SOLUTION: MPEG data of a desired program outputted from a demultiplexer 14 is recorded on a hard disk 18. When the vacant capacity on the hard disk 18 is less, pictures stored on the hard disk 18 and having a longer relative time from a just preceding I picture are deleted from the hard disk 18. The pictures having a longer relative time from the just preceding I picture are not recorded on the hard disk 18 afterwards.
