FILE RECORDING DEVICE

摘要

A file recording device for effectively recording files into a semiconductor memory, and a filter driver. A file buffer is prepared which is associated with a file into which data is to be recorded, and the data to be recorded is accumulated in the file buffer. It is determined whether the accumulated data reaches a block size that is an erasing unit of the semiconductor memory. When it is determined that the accumulated data reaches the block size, the data is written into an open block in the semiconductor memory. Alternatively, when there is a request for recording data into a plurality of files, and the data size of the file buffer for those files reaches the block size, the data is written into an open block. Alternatively, when there occurs a series of write addressings from a filter driver to the semiconductor memory device, the data is accumulated in the data buffer, and when the data writing destinations reach a block limit, the data is written.
