<p>A data recording apparatus includes a slot for receiving a memory card having a disk, a flash memory and a controller. Each time one frame of compressed image data is recorded to the disk, a vacant capacity value of the disk is written to the flash memory. This vacant capacity value is read out according to an instruction given from a CPU. When the vacant capacity of the disk is lower than the vacant capacity of a compressed image area formed in an SDRAM, the CPU invalidates the vacant capacity of the compressed image area in a portion exceeding the vacant capacity of the disk. This restricts the number of frames to be picture-taken. <IMAGE></p> |
