Computer-readable medium storing data editing program

A non-transitory computer-readable medium storing a data editing program causing a computer to execute data editing processing of a recording medium including a data region which is provided with a plurality of clusters and in which a data file is recorded in the cluster units, and a management region where management data managing the data file are recorded, the data editing processing comprising:

• transferring insert data between a transfer start position and a transfer end position in a transfer source file to a transfer insertion position in a transfer destination file;
• the transferring the insert data including:
• when a sum total of a size of transfer-start-back-data at and after the transfer start position in a transfer start cluster having the transfer start position of the transfer source file and a size of transfer-end-forward-data at and before the transfer end position in a transfer end cluster having the transfer end position of the transfer source file is greater than the size of a cluster,
• transferring the transfer-start-back-data to a first new cluster in which the transfer source file and the transfer destination file have not been recorded, the first new cluster being included in the plurality of clusters;
• transferring transfer-insertion-back-data at and after the transfer insertion position in a transfer insertion cluster having the transfer insertion position of the transfer destination file to the second new cluster in which the transfer source file and the transfer destination file have not been recorded, the second new cluster being different from the first new cluster and being included in the plurality of clusters, and
• editing the management data with respect to the transfer destination file, such that the transfer insertion cluster is linked before the first new cluster, the cluster which is next to the transfer start cluster is linked after the first new cluster, the transfer end cluster is linked before the second new cluster, and a cluster which is next to the transfer insertion cluster is linked after the second new cluster.

A non-transitory computer-readable medium storing a data editing program causing a computer to execute data editing processing of a recording medium including a data region which is provided with a plurality of clusters and in which a data file is recorded in the cluster units, and a management region where management data managing the data file are recorded, the data editing processing comprising:

• inserting insertion data to an insertion position in an insertion destination file;
• the inserting the insertion data including:
• transferring data at and after the insertion position in an insertion cluster having the insertion position of the insertion destination file and the insertion data to one or a plurality of third new clusters in which the insertion destination file has not been recorded, the third new clusters being included in the plurality of clusters;
• and
• editing the management data such that a cluster preceding the insertion cluster is linked before a head cluster of the third new clusters, and a cluster which is next to the insertion cluster is linked after a tail cluster of the third new clusters.

A non-transitory computer-readable medium storing a data editing program causing a computer to execute data editing processing of a recording medium including a data region which is provided with a plurality of clusters and in which a data file is recorded in the cluster units, and a management region where management data managing the data file are recorded, wherein

• the data editing processing comprising:
• removing data between a removal start position and a removal end position in a removal source file;
• the removing the data including:
• deleting data at and after the removal start position in a removal start cluster having the removal start position of the removal source file and data at and before the removal end position in a removal end cluster having the removal end position;
• and
• editing the management data such that the removal end cluster is linked after the removal start cluster.

A non-transitory computer-readable medium storing a data editing program causing a computer to execute data editing processing of a recording medium including a data region in which a data file is recorded in cluster units of fixed length, and a management region where management data managing the data file are recorded, the data editing processing comprising:

• storing, in a data tail of an object file of the data editing processing, editing instruction information, which is inputted and includes an editing type indicating either of insertion processing and removal processing, an editing object position indicating either of an insertion position in the insertion processing and a removal start point in the removal processing, and an editing object size indicating either of a size of insertion data in the insertion processing or a deletion size in the removal processing;
• performing data editing of any of data insertion, data removal, and data transfer with respect to the object file of the data editing processing on the basis of the inputted editing instruction information;
• changing a cluster configuration of the object file of the data editing processing so as to correspond to the data editing with respect to the management data;
• and
• restoring the object file of the data editing processing to a state before or after the data editing processing on the basis of the editing instruction information, when reading of the object file of the data editing processing is not able to be performed.
