Description

  The present invention relates to an accumulation recording method and an accumulation recording apparatus capable of accumulating and moving contents.

  In recent years, digitalization of contents has progressed, and broadcasting such as BS, CS, and terrestrial broadcasting in Japan and overseas, CATV, tapes and disks for recording the same, etc. are digitized.

  Digital transmission and digital recording can be densified by using compression techniques compared to analog transmission analog recording. For example, in digital broadcasting, analog television broadcasting (standard image quality: 480 effective scanning lines interlace method, hereinafter abbreviated as 480i) can transmit three channels of standard image quality digital video data using radio waves of one channel. Further, if radio waves for one channel of analog television broadcasting are used, high image quality (480 effective scanning lines progressive system: 480p, progressive scanning lines 720 progressive system: 720p, effective scanning lines 1080 interlace system: 1080i, etc. ) Digital video data can be transmitted. The sound is also digitally compressed and is 5.1ch (in addition to the 5 channels on the right front, center front, left front, right rear, and left rear, the frequency band is about 1/10 (0 to 200 Hz) and 0 compared to the 5 channels. Data consisting of low frequencies counted as one channel). Furthermore, in addition to video and audio, data such as characters, control information, and programs can be transmitted.

  Further, since digital content is digital data, there is an advantage that it can be copied without deterioration as in analog.

  However, unlimited content reproduction infringes copyright. For this reason, copyright protection functions are required for digital devices.

  For example, in domestic BS, broadband CS, and terrestrial digital broadcasting, the content to be protected must be protected by the methods described in Non-Patent Documents 1 and 2.

  That is, the contents specified for protection by the digital copy control descriptor and the content use descriptor included in the broadcast MPEG-TS stream are stored in a storage unit (for example, a hard disk device, a semiconductor memory). Etc.), it must be encrypted so that it can be played back only by the device. Further, the content broadcast as “copyable only for one generation” is updated to “recopy prohibited” and stored. “Recopy prohibited” content can be moved only to one recording medium approved in Non-Patent Documents 1 and 2. When moved, the original content of the move is disabled. In addition, content broadcasted as “copyable only for one generation” is allowed to be updated to “re-copy prohibited” up to two recording media approved in Non-Patent Documents 1 and 2 and recorded directly. Yes.

FIG. 19 is a block diagram of a conventional storage and recording apparatus for recording digital broadcast content in accordance with the recording method described above. In FIG. 19, reference numeral 1901 denotes an accumulation recording apparatus. 1902 is a receiving means for receiving a digital broadcast signal and outputting an MPEG2-partial transport stream (partial TS), 1903 is an accumulating means for accumulating the partial TS, 1904 is an accumulation file accumulated in the accumulating means 1903,
1907 is a first recording medium first drive means for writing the accumulation file 1904 to the first recording medium 1908, 1908 is the first recording medium, 1909 is the first recording file written to the first recording medium 1908,
1910 is a second recording medium second drive means for writing the partial TS in the second recording medium 1911, 1911 is the second recording medium, 1912 is the second recording file written in the second recording medium 1911,
1913 is a third recording medium drive means for writing the partial TS on the third recording medium 1914, 1914 is the third recording medium, 1915 is a third recording file written on the third recording medium 1914,
Reference numeral 1916 denotes reproduction means for reproducing the stored file 1904, and 1917 denotes user interface means.

  The operation of the conventional storage and recording apparatus configured as described above will be described.

  Of the partial TS output by the receiving unit 1902, the digital copy control descriptor included in the stream and the content designated for protection by the content use descriptor can be reproduced in the storage unit 1903 only by the storage recording device 1901. Encryption is performed so that the file can be stored as a storage file 1904. Furthermore, content whose digital copy control descriptor is “copyable only for one generation” is updated to “recopy prohibited” and stored. The format of the accumulation file 1904 is not particularly limited. The partial TS may be used as it is, or it may be converted into a program stream (PS) or a unique format. Also, conversion of resolution, bit rate, etc. may be performed.

  The accumulated file 1904 accumulated as “recopy prohibited” is moved as a recording file 1909 on the first recording medium 1908 via the first recording medium drive means 1907. The first recording medium 1908 is limited to a recording medium compatible with the content protection method approved in Non-Patent Documents 1 and 2. When the file is moved, the stored file 1904 that is the move source is disabled to be reproduced.

  Content whose digital copy control descriptor is “copyable only for one generation” is recorded as a second recording file 1912 on the second recording medium 1911 via the second recording medium drive means 1910. . Further, it is recorded as a third recording file 1915 on the third recording medium 1914 via the third recording medium drive means 1913. The second recording medium 1911 and the third recording medium 1914 are recording media approved in Non-Patent Documents 1 and 2 described above.

  In FIG. 19, for the sake of simplicity, the storage file 1904 can be moved only to the first recording medium 1908. However, if the number of moving destinations can be limited to one, the first recording medium 1908, the first recording medium 1908, and the like. It can be moved to either the second recording medium 1911 or the third recording medium 1914. It is also possible for the user to designate the move destination recording medium via the user interface 1917.

Further, the accumulated file 1904 is reproduced via the reproducing means 1916. The user interface unit 1917 superimposes operation information or the like on the output signal of the reproduction unit 1916 as necessary, and outputs it as an AV signal.

  However, in the conventional storage / recording apparatus, only one file can be stored in the storage means, and therefore it can be moved to only one recording medium.

  Since the broadcast means can store the broadcast content as it is in high resolution (HD), the high resolution (HD) content can be reproduced and enjoyed. However, some recording media may be recorded after conversion to a standard resolution (SD) or lower due to format and bit rate restrictions. When moving to such a recording medium, HD image quality cannot be enjoyed.

  Some recording media cannot be moved from one medium to another once they are recorded. Some media to be moved, such as D-VHS, are not suitable for portable use, and their usage is limited.

  In addition, the storage means generally has a large capacity and can be accessed at high speed, and has the convenience that broadcast contents are recorded and stored in the storage means so that the user can enjoy what they want to see at any time. On the other hand, the storage means has a risk of annihilating the contents recorded and stored due to failure. For this reason, the contents to be stored are moved to the recording medium, but generally the recording medium has a smaller capacity than the storage means, is slow to access, and becomes unusable. Therefore, it is difficult to achieve both convenience and safety in the conventional storage / recording apparatus.

  Even with conventional storage and recording devices, it is allowed to record directly onto a recording medium at the same time as the storage, but generally the capacity of the recording medium is small compared to the capacity of the storage medium, the content that can be recorded is limited, and the storage means stores it. Convenience is worse than when you do. Further, in a recording medium that can be written only once, a recording medium that has been recorded once cannot be reused and is uneconomical.

  However, if unrestricted copying from the storage means is allowed, there is a risk of promoting infringement of the rights of the copyright holder, such as the appearance of a person who sells copied content.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a storage and recording apparatus that achieves both user convenience and copyright holder rights protection.

  In order to solve the above-described conventional problems, the storage and recording apparatus of the present invention includes storage means and recording medium drive means corresponding to at least one move, and receives received content as a storage file and a specific one. It is stored in the storage means as a moving storage file that can be moved to only one recording medium.

  In addition, the storage and recording apparatus of the present invention includes storage means and recording medium drive means corresponding to at least one move, and specifies a storage file that can move received content to any recording medium, Are stored in the storage means as a moving storage file that can be moved to only one recording medium.

  According to the storage and recording apparatus of the present invention, it is possible to provide a storage and recording apparatus that achieves both convenience for the user and protection of the copyright holder's rights by using the storage file and the storage storage file. That is, the number of contents finally remaining is limited by the total number of storage files and movement storage files, and the rights of the copyright holder are appropriately protected. On the other hand, even after the user moves the storage file for movement to the corresponding recording medium, the storage file remains in the storage recording device, and the user can enjoy the content as received. Also, the received content can be recorded on several recording media, and the usability restrictions are eased.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  First, terms used in the following description will be described.

  Recording content in storage means (for example, a hard disk device, a semiconductor memory device, etc.) built in the recording storage device is called “storage”. On the other hand, recording on a removable recording medium (such as first, second, and third recording media used in the following description) is called “recording”.

  “Move” refers to copying the stored or recorded content to another storage medium or recording medium, and making the copy source content unreproducible. Some media can and cannot be moved. For example, HDD devices, SD memory cards, memory sticks, and the like can be move sources, but DVD-RAM, DVD-RW, DVD-R, BD-RE, D-VHS, and the like cannot be move sources.

  Making a file unplayable refers to a general method for making a file unplayable, such as deleting a file, making playability information in the file management information unplayable, and deleting an encryption key in the case of encrypted content. It does not necessarily mean deletion.

(Embodiment 1)
The first embodiment is an example in which both the accumulated file and the move accumulated file can be reproduced, and the move accumulated file remains as it is after the accumulated file is moved.

FIG. 1 is a block diagram of Embodiment 1 of the apparatus of the present invention. Reference numeral 101 denotes an accumulation recording apparatus. 102 is a receiving means for receiving a digital broadcast and outputting an MPEG2-partial transport stream (partial TS) as content; 103 is a storage means for storing content; 104 is a storage file; 105 is a storage file for the first move; 106 is the second move accumulation file,
107 is a first recording medium drive means for recording the storage file 104 on the first recording medium 108, 108 is a first recording medium, 109 is a first recording file recorded on the first recording medium 108,
110 is a second recording medium drive unit that records the first moving storage file 105 on the second recording medium 111, 111 is the second recording medium, and 112 is the second recording medium recorded on the second recording medium 111. 2 recording files,
Reference numeral 113 denotes third recording medium drive means for recording the second moving storage file 106 on the third recording medium 114, 114 denotes the third recording medium, and 115 denotes the third recording medium recorded on the third recording medium 114. 3 recording files,
Reference numeral 116 denotes reproduction means for reproducing files stored in the storage means 103, and 117 denotes user interface means.

The first recording medium 108, the second recording medium 111, and the third recording medium 114 are limited to recording media compatible with the content protection method approved in Non-Patent Documents 1 and 2. For example, it supports Blu-ray Disc (BD) compatible with Content Protection System for Blu-ray Disc Rewritable (CPS for BD-RE), D-VHS cassette compatible with D-VHS format, and Content Protection for Recordable Media (CPRM) DVD-RAM, DVD-RW, DVD-R, MagicGate Type-R for Secure Video Recording (MG-R (SVR)) for Memory Stick PRO compatible memory stick, MagicGate Type-R for Secure Video Recording (MG- R (SVR)) Hi-MD compatible with Hi-MD, SD memory card compatible with Content Protection for Recordable Media (CPRM), and the like. If new recording media and content protection methods are approved in the future, they can also be used. In addition, when recording content designated for protection on the recording medium, it must be protected by each content protection method. The operation of the storage and recording apparatus 101 of the first embodiment configured as described above is performed. explain.

  The protection of the partial TS output by the receiving unit 102 is specified by a descriptor included in the stream. There are three states for specifying protection: (1) copying is possible without restriction conditions, but output protection is performed, (2) copying is possible only for one generation, and (3) copying is prohibited. Furthermore, (4) “Copyable without constraint” is defined as a state in which protection is not designated. Here, in the state of specifying protection, (1) “coding is possible without restriction conditions, but output protection” means that there is no copy number and copy generation restrictions, but on the permitted recording medium, storage means, and transmission medium. Shows a state in which reproduction and duplication are performed only by an authorized device protected by encryption.

  The content for which protection is designated is encrypted in the storage means 103 so that it can be played back only by the storage recording device 101 and stored as a storage file 104. Content that is “copyable for only one generation” is updated to “recopy prohibited” when it is accumulated. The format of the accumulation file 104 is not particularly limited. The partial TS may be used as it is, or it may be converted into a program stream (PS) or a unique format. Also, conversion of resolution, bit rate, etc. may be performed.

  In the partial TS output by the receiving unit 102, the content of “copyable for only one generation” is encrypted in the storage unit 103 so that it can be reproduced only by the storage recording device 101 by updating it to “recopy prohibited”. Are stored as a first move storage file 105 and a second move storage file 106. The move accumulation file will be described later.

  The storage file 104 stored as “recopy prohibited” is moved as a recording file 109 onto the first recording medium 108 via the first recording medium drive means 107. For the move, the first recording medium drive unit 107 converts the format, resolution, bit rate, and the like of the storage file 104 as necessary. When the file is moved, the stored file 104 that is the move source is disabled to be reproduced.

  In FIG. 1, the storage file 104 is configured to be moved only to the first recording medium 108, but may be moved to another recording medium as long as the number of moving destinations can be limited to one. It is also possible for the user to designate the move destination recording medium via the user interface means 117. Furthermore, the move destination of the accumulation file 104 may be a transmission medium corresponding to the move. For example, it is possible to use an IEEE 1394 bus corresponding to a content protection system DTCP (Digital Transmission Content Protection) as a transmission medium.

  The first move file 105 stored as “recopy prohibited” is moved as the second recording file 112 on the first recording medium 111 via the second recording medium drive unit 110. During the move, the second recording medium drive unit 110 converts the format, resolution, bit rate, and the like of the first move storage file 105 as necessary. In the case of the move, the first move accumulation file 105 that is the move source is disabled. The first move accumulation file 105 cannot be moved except for moving as the second recording file 112 on the second recording medium 111.

  The second move file 106 stored as “recopy prohibited” is moved as the third recording file 115 onto the third recording medium 114 via the third recording medium drive means 113. For the move, the third recording medium drive unit 113 converts the format, resolution, bit rate, and the like of the second move storage file 106 as necessary. When moved, the second move storage file 106 which is the move source is disabled to be played back. The second moving storage file 106 cannot be moved except for moving as the third recording file 115 on the third recording medium 114.

  The storage file 104, the first move storage file 106, and the second move storage file 107 are played back via the playback means 116. More specifically, a file encrypted and recorded on the storage means 103 is decrypted and decoded according to each format to generate a baseband signal. The user interface unit 117 superimposes operation information and the like on the output signal of the reproduction unit 116 as necessary, and outputs it as an AV signal. In addition, an AV signal is directly displayed on a device incorporating a display means. The output and display will be described later.

  The move storage file will be described. The move storage file is a file stored so that it can be moved only to the recording medium that is the move destination. For example, information for specifying the recording medium is recorded in the file header as a move destination, and control is performed so that the information is moved only to the recording medium according to the specification information. The specific information is also protected by encryption to prevent falsification.

  Further, the move storage file may be stored in a recording format (application format) of the recording medium or a format in the middle of the process of converting to the recording format of the recording medium. For example, when the recording medium is a DVD-RAM and the recording format is a video recording format (hereinafter referred to as a VR format), the partial TS is converted to PS, and a pack / packet structure used in the VR format is formed. Then, the content having the pack / packet structure is encrypted with the C2 cipher used in CPRM, using the key generated by the random number generation means. (However, when additional recording is performed on a DVD-RAM that has already been recorded with CPRM, the additional content is also encrypted using the encryption key information recorded on the DVD-RAM at the time of previous CPRM recording. The content encrypted with the key generated by the generating means cannot be directly added to the DVD-RAM, but once decrypted, it is re-encrypted and appended using the encryption key information read from the DVD-RAM again. The accumulation of the format during or after these processes is defined as a move accumulation file.

  Note that resolution, bit rate, and the like may be converted as long as they can be moved to the recording medium.

  In the first embodiment, an example of a storage recording apparatus incorporating three recording medium drive means is described. Even in the case of an accumulation recording apparatus incorporating two recording medium drive means, it is possible to accumulate one accumulation file and two movement accumulation files. This is to ensure the convenience of the user such as playing back and viewing the stored file even after moving the two stored files. However, in the case of an accumulating / recording apparatus having only one recording medium drive means, the number of moving accumulating files is limited to one. This is because there is only one type of recording medium to be moved.

  Next, display and operation of the storage / recording apparatus 101 will be described.

  First, the user interface unit 117 will be described.

  FIG. 2 is a block diagram showing an example of the configuration of the user interface unit 117. In FIG. 2, 201 is a display image generating means, 202 is a synthesizing means, and 203 is a receiving means. The display interface generating unit 201 to the receiving unit 203 constitute a user interface unit 117. Reference numeral 204 denotes a display device external to the storage recording apparatus 101, and 205 denotes a remote controller attached to the storage recording apparatus 101. The remote controller 205 includes at least a function selection key 206, an up arrow key 207, a down arrow key 208, a left arrow key 209, a right arrow key 210, a decision key 211, a program guide key 212, a program navigation key 213, A stop key 214 and a reproduction key 215 are provided. There are many other keys, but they are omitted here. In FIG. 2, the display device 204 and the remote controller 205 are external to the storage recording device 101, but may be incorporated in the storage recording device 101. For example, control can be performed using a liquid crystal display device (not shown) and a button (not shown) of the storage / recording apparatus 101.

  The display video generation unit 201 generates a display video (such as a menu screen) based on user display data sent from each part of the storage / recording apparatus 101. When reproducing the received content or the accumulated content on the storage / recording apparatus 101, the synthesizing unit 202 superimposes or switches the reproduction signal and the display video of the display video generation unit 201 on the outside of the storage / recording apparatus 101. AV signal to be output to. The receiving unit 203 receives a signal from the remote controller 205 and outputs a control signal to each unit in the storage / recording apparatus 101. The display device 204 is a device that displays the AV signal of the storage / recording device 101, such as a television or a liquid crystal projector. The remote controller 205 includes a key for controlling the storage / recording apparatus 101, and transmits a control signal based on the key operation to the storage / recording apparatus 101 using infrared rays, radio waves, and the like.

  Hereinafter, the operation will be described with a focus on the user interface means 117.

  As a procedure for storing digital broadcast contents, first, the program guide key 212 of the remote controller 205 is pressed to call up the program guide screen. FIG. 3 shows an example of the program guide screen. Source information (broadcast station name), recording date and time (broadcast date and time), genre, copyright management information, title, short format program description as part of the management information of the currently selected program on the upper left A program guide for each broadcasting station is displayed below the displayed program guide. The program currently selected in the program guide is highlighted. In FIG. 3, “Sometimes Momotaro” broadcast from 17:00 on the DDD TV is selected. The user uses the arrow keys on the program guide screen to select a program (content) to be stored. If the accumulation key 213 is pressed while a certain program is selected, an accumulation request is issued immediately if the selected program is currently being broadcast, and an accumulation reservation is made if the program is scheduled to be broadcast in the future. In the case of an accumulation reservation, an accumulation request is issued at the reservation time.

When there is a content accumulation request, the digital broadcast receiving unit 102 is caused to generate a partial TS and management information of the content. When the content is “copyable only for one generation”, the content is encrypted and stored in the storage medium 104 with the “recopy prohibited” storage file 104, the first move storage file 105, and the second move storage. Accumulated as file 106. However, it may be possible to select whether all the three files are stored or only the specified file is stored by specifying the initial setting.
The content storage operation procedure has been described above.

  Next, the reproduction / move operation will be described. As a procedure of the reproduction / move operation, first, the program navigation key 213 of the remote controller 205 is pressed to call the program navigation screen. The program navigation screen has two display screens, a title list screen and a thumbnail screen. These two display screens are alternately displayed each time the program navigation key 213 is pressed. FIG. 4 shows a display example of the program navigation / title list screen, and FIG. 5 shows a display example of the program navigation / thumbnail screen.

  In the program navigation / title list screen of FIG. 4, a title list 401 and a thumbnail 402 are displayed.

  The title list 401 displays No, recording date, day of the week, CH (channel), start time, title, and moveability status for each recording medium for each accumulated content. In this example, BD is used as the first recording medium, DVD-RAM is used as the second recording medium, and SD memory card is used as the third recording medium. No assigns a 3-digit serial number in the order of accumulation. The recording date, day of the week, CH (channel), start time, and title are content information acquired from the management information of the digital broadcast. The move availability status for each recording medium is indicated by “◯” indicating that the move is possible and “X” indicating whether the move is possible. The move availability status corresponds to the existence status of the accumulation file 104, the first move accumulation file 105, and the second move accumulation file 106 for each content, and if it exists, the move is permitted. If the stored file is moved to the recording medium and cannot be played back, or if playback is disabled by a user operation, or if the file does not exist due to the setting of not being stored, the move is rejected.

  The user selects content using the arrow keys of the remote controller 205. In the example of FIG. 4, “classic hour” is displayed with the background color changed, indicating that it is in a selected state. In addition, the right arrow key 209 and the left arrow key 210 are used to select a recording medium that can be moved (displayed in circles) in the move enabled / disabled state. In FIG. 4, the DVD is displayed with a different background color, indicating that it is in a selected state. When the playback key 215 is pressed in this state, playback of “classic hour” and “DVD” is started. That is, the first move accumulation file 105 corresponding to “classic hour” is reproduced. Further, when the determination key 211 is pressed while the “classic hour” or “DVD” is selected, the move is started. That is, the first moving storage file 105 corresponding to “classic hour” is moved as the second recording file 112 on the second recording medium 111 via the second recording medium drive unit 110. After the move, the first move accumulation file 105 corresponding to “classic hour” is disabled to be reproduced, and the move enable / disable state changes to a move reject display (× display).

  In the thumbnail 402, a thumbnail of the currently selected content is displayed. In the example of FIG. 4, since “classic hour” and “DVD” are selected, the first move accumulation file 105 corresponding to “classic hour” is displayed. The display may be a still image or a thumbnail size video. When a thumbnail is selected using the arrow keys, it can be displayed as a moving image, otherwise it can be displayed as a still image.

  On the program navigation / thumbnail screen of FIG. 5, a list of contents using thumbnails is displayed.

  Reference numeral 502 denotes a thumbnail screen, 503 denotes No, 504 denotes attached information (recording date, day of the week, CH, title), and 505 denotes whether or not each recording medium can be moved. The contents from 502 to 505 are combined into one content. A list of thumbnails for each content is displayed.

  The user selects content using the arrow keys of the remote controller 205. In the example of FIG. 5, “classic hour” is displayed with the background color changed, indicating that it is in a selected state. In addition, using the arrow keys, a recording medium that can be moved (displayed in circles) is selected from the movable state. In FIG. 5, the DVD is displayed with a different background color, indicating that it is in a selected state. When the playback key 215 is pressed in this state, playback of “classic hour” and “DVD” is started. That is, the first move accumulation file 105 corresponding to “classic hour” is reproduced. Further, when the determination key 211 is pressed while the “classic hour” or “DVD” is selected, the move is started. That is, the first moving storage file 105 corresponding to “classic hour” is moved as the second recording file 112 on the second recording medium 111 via the second recording medium drive unit 110. After the move, the first move accumulation file 105 corresponding to “classic hour” is disabled to be reproduced, and the move enable / disable state changes to a move reject display (× display).

  Each thumbnail screen displays an accumulation file 104 of each content as an initial state. However, the moving storage file is displayed for the content in which the storage file 104 has been moved. For example, since the content 510 displaying “Travel in hot spring” has only the second move accumulation file for the SD memory card, the thumbnail screen has a small number of SD pixels.

  Furthermore, it is also possible to edit the selected accumulation file or move accumulation file. In the editing operation, for example, the accumulation file or the movement accumulation file is divided into small units called chapters. The chapter division is performed, for example, by pressing a chapter key (not shown) of the remote controller 205 during reproduction of the file. When a file divided into chapters is selected on the program navigation screen, the function selection key 206 is pressed to call a function menu, and when a chapter list display is selected, a thumbnail list of each chapter is displayed. For example, when an unnecessary chapter is to be deleted, the chapter is selected by the arrow key, the chapter menu is called by the function selection key 206, the chapter deletion is selected from the chapter menu, and the enter key 211 is pressed. In addition, chapters can be moved.

  As for erasure of contents, when the function selection key 206 is pressed in the selected state of contents to be erased on the program navigation screen, a menu is displayed, and erasure is selected from the menu.

  As described above, according to the first embodiment, the content in the “copy only for one generation” state is stored in the “recopy prohibited” state as an accumulation file and a move accumulation file. The moving storage file can be moved only to a recording medium corresponding to the built-in recording medium drive means, and unlimited copying of contents can be prevented, and the copyright holder's rights are appropriately protected. On the other hand, the user can move the storage file for movement to a recording medium corresponding to the built-in recording medium drive means, and can also reproduce or move the storage file independently of these. In addition, since the move accumulation file can also be reproduced, reproduction from the accumulation means is possible even when the accumulation file is moved first, and there is no need to worry about the order of the move. In addition, since the move accumulation file can also be reproduced, the move accumulation file can be edited. In addition, since it is displayed whether or not each recording medium can be moved, it is easy to select a moving destination recording medium. As described above, Embodiment 1 can provide a storage and recording apparatus that achieves both user convenience and copyright holder rights protection.

(Embodiment 2)
The second embodiment is an example in which both the accumulation file and the movement accumulation file can be reproduced, and the movement accumulation file is deleted after the accumulation file is moved.

  The basic configuration of the storage and recording apparatus of the second embodiment is the same as that shown in FIG.
