1. A recording apparatus, comprising:
a recording unit configured to record a moving image signal in a recording medium by storing the moving image signal in a moving image file in accordance with a file system, wherein the recording unit starts recording the moving image signal in accordance with a recording start instruction and stops recording of the moving image signal in accordance with a recording stop instruction, wherein the moving image signal recorded in the recording medium is deleted in units of the moving image file and a recording area in which a moving image signal stored in the deleted moving image file had been recorded is managed as a remaining capacity of the recording medium; and a control unit configured to control, in a loop recording mode, the recording unit to repeatedly record the moving image signal in a predetermined recording area for the loop recording mode in a period from the recording start instruction to the recording stop instruction, by dividing the moving image signal into a predetermined number of moving image files, wherein the control unit determines an upper limit of a file size of each of the predetermined number of moving image files to be recorded in the loop recording mode, according to a recording capacity of the predetermined recording area, wherein in the loop recording mode, the control unit controls the recording unit to divide the moving image file every time a file size of the moving image file being recorded reaches the upper limit so that the file size of each of the predetermined number of moving image files recorded in the loop recording mode does not exceed the upper limit and the moving image signal of a recording time length corresponding to the file size of the upper limit is stored in each of a plurality of moving image files, each of which has the file size of the upper limit, and has been recorded in the loop recording mode, wherein each of the predetermined number of moving image files recorded in the loop recording mode is managed as a file according to the file system, and wherein if a remaining capacity of the predetermined recording area is determined to have run out in the loop recording mode, the control unit controls the recording unit to delete a moving image file recorded first, from among the predetermined number of moving image files recorded after the recording start instruction in the loop recording mode so that a remaining capacity corresponding to the file size of the upper limit is obtained, and to continue recording the moving image signal in a recording area, which has a capacity corresponding to the file size of the upper limit and in which the moving image signal stored in the deleted moving image file had been recorded. |
