Abstract

The invention provides an information processing apparatus, a recording method and a computer program. There is provided an information processing apparatus which records data in a recording medium including: a recording section which records data in the recording medium; a detecting section which detects continuous or fragmented free areas in minimum allocation unit of the recording medium; and a recording control section (130) which controls the recording section so that the recording section sequentially records data in the continuous free areas of the recording medium detected by the detecting section, and at the time point when the recording is completed, the recording section moves an end portion of the recorded data to the fragmented free areas of the recording medium detected by the detecting section so as to be recorded.

Description

technical field [0001] The present invention relates to an information processing device, a recording method, and a computer program. More specifically, the present invention relates to an information processing device, a recording method, and a computer program that record data in a recording medium in units of files. Background technique [0002] Nonvolatile semiconductor memories typified by flash memory are being miniaturized and their capacities are being expanded, so that they are frequently used to record high-capacity data such as video data and audio data. [0003] Generally, a flash memory has a read / write unit called a page and a data deletion unit called a deletion block. The size of the delete block is an integer multiple of the page size. For example, the page size may be 2K bytes, and the delete block size may be 32K bytes corresponding to 16 times the page size. Image 6 It is an explanatory diagram showing the relationship between deleted blocks and pages ...
