a generating unit configured to generate first position information regarding a position of the moving image data in the first area and second position information which can represent a larger value than the first position information with respect to the position of the moving image data in the first area; and a control unit configured to control the recording unit so as to store both of the first position information and the second position information generated by the generating unit into the second area to record the moving image file into the recording medium. ### Claim 2 (depends on 1) An apparatus according to claim 1, wherein the control unit controls the recording unit in such a manner that when a size of the moving image file recorded in the recording medium exceeds a predetermined threshold value, both of the first position information and the second position information are stored into the second area, and when the size of the moving image file recorded in the recording medium does not reach the predetermined threshold value, the second position information is not stored into the second area and the first position information is stored into the second area. ### Claim 3 (depends on 1) An apparatus according to claim 1, wherein the generating unit generates both of the first position information and the second position information in accordance with recording of the moving image file being started, and the control unit controls the generating unit in such a manner that when the size of the moving image file which is being recorded exceeds the predetermined threshold value, the generation of the first position information is stopped and the second position information is generated. ### Claim 4 (depends on 1) An apparatus according to claim 1, wherein the moving image data stored in the first area is constructed with a plurality of units and each of the first position information and the second position information is information regarding the positions of a plurality of units included in the moving image data. ### Claim 5 (depends on 1) An apparatus according to claim 1, wherein the recording unit stores the second position information into a position near a head of the moving image file than the first position information. ### Claim 6 (depends on 1) An apparatus according to claim 1, further comprising an instructing unit configured to instruct start and stop of the recording of the moving image file into the recording medium, and wherein the control unit generates the second area for storing the first and second position information, in accordance with the instruction of the recording start by the instructing unit, the control unit discriminates whether or not the size of the moving image file exceeds the threshold value in accordance with the instruction of the recording stop, and in accordance with a result of the discrimination, the control unit controls the generating unit and the recording unit in such a manner that when the size of the recorded moving image file does not exceed the threshold value, the second position information is not stored in the second area and the first position information is stored into the second area and recorded into the recording medium, and when the size of the recorded moving image file exceeds the threshold value, the first position information and the second position information are stored into the second area and recorded into the recording medium. ### Claim 7 (depends on 1) An apparatus according to claim 1, wherein the threshold value is set on the basis of a maximum value of values which the first position information can represent. ### Claim 8 A control method of a recording apparatus having a recording unit configured to record a moving image file including a first area for storing moving image data and a second area for storing meta data into a recording medium, comprising: a generating step of generating first position information regarding a position of the moving image data in the first area and second position information which can represent a larger value than the first position information with respect to the position of the moving image data in the first area; and a control step of controlling the recording unit so as to store both of the first position information and the second position information generated in the generating step into the second area to record the moving image file into the recording medium. ### Claim 9 (depends on 8) A non-transitory computer-readable storage medium storing a program comprising codes for causing a computer to execute the control method according to claim 8. ### Claim 10 A recording apparatus comprising: a recording unit configured to store moving image data and audio data in an information file of MP4 file format and to record the information file on a recording medium; a generating unit configured to generate stco box and co64 box during recording of the information file; and a control unit configured to control the recording unit to store both the stco box and the co64 box in moon box of the information file recorded on the recording medium. ### Claim 11 (depends on 10) An apparatus according to claim 10, wherein the generating unit generates the stco box indicating chunk offsets of predetermined chunks of moving image data and audio data stored in the information file and the co64 box indicating chunk offsets of the predetermined chunks and chunks other than the predetermined chunks. ### Claim 12 (depends on 11) An apparatus according to claim 11, wherein the predetermined chunks correspond to the moving image data and the audio data recorded before a size of the information file reaches a threshold, and the other chunks correspond to the moving image data and the audio data recorded after the size of the information file reaches the threshold. ### Claim 13 (depends on 12) An apparatus according to claim 12, wherein the threshold is 4 gigabytes. ### Claim 14 (depends on 10) An apparatus according to claim 10, wherein if a size of the information file does not reach a threshold, the control unit controls such that the co64 box is not stored in the moov box. ### Claim 15 A control method of a recording apparatus including a recording unit configured to store moving image data and audio data in an information file of MP4 file format and to record the information file on a recording medium, comprising: generating stco box and co64 box during recording of the information file by the recording unit; and controlling the recording unit to store both the stco box and the co64 box in moov box of the information file recorded on the recording medium. ### Claim 16 (depends on 15) A non-transitory computer-readable storage medium storing a computer program comprising a program code for causing a computer to execute the control method according to claim 15.
