A content recording apparatus (10) includes an MPEG-4 codec (34). Compressed motion image data output from the MPEG-4 codec (34) in photographing a motion image is a motion image content which expresses a continuous change with time and has an I frame allocated intermittently. A CPU (40) records the compressed motion image data onto a recording medium (38). The CPU (40) also creates motion image index data pointing each frame of the compressed motion image data output from the MPEG-4 codec (34) in parallel with the compression operation by the MPEG-4 codec (34). The created motion image index data is recorded onto the recording medium (38) by the CPU (40) every time that the I frame is specified.
