Editing apparatus and editing method
First Claim
1. An editing apparatus for editing data files recorded in a nonvolatile memory, wherein the nonvolatile memory comprises a data area for recording said data files, each of said data files being recorded in blocks of a predetermined data length along with an attribute file of a predetermined length, and a management area for recording management data for managing said data files, the editing apparatus comprising:
- operating means for selecting two of said data files to be combined;
separating means for separating a backward attribute file from a backward side data file of the selected two data files;
editing means for editing the management data recorded in the management area so as to logically link the selected two data files and for editing a forward attribute file corresponding to a forward side data file of the selected two data files; and
recording means for recording the edited management data to the management area and recording the edited forward attribute file to the data area.

Abstract
An editing apparatus and method for dividing or combining a data file(s) that is segmented into blocks of a predetermined data length and recorded in a non-volatile memory. An attribute file having a predetermined length is modified so as to reflect such dividing or combining. Such attribute file is recorded in the non-volatile memory.

13. An editing method for editing data files recorded in a nonvolatile memory, wherein the nonvolatile memory comprises a data area for recording said data files, each of said data files being recorded in blocks of a predetermined data length along with an attribute file of a predetermined length, and a management area for recording management data for managing said data files, the editing method comprising the steps of:
-
selecting two of said data files to be combined;
separating a backward attribute file from a backward side data file of the selected two data files;
editing the management data recorded in the management area so as to logically link the selected two data files;
editing a forward attribute file corresponding to a forward side data file of the selected two data files;
recording the edited management data to the management area; and
recording the edited forward attribute file to the data area.

14. An editing apparatus for editing data files recorded in a nonvolatile memory, wherein the nonvolatile memory comprises a data area for recording said data files, each of said data files being recorded in blocks of a predetermined data length along with an attribute file of a predetermined length, and a management area for recording management data for managing said data files, the editing apparatus comprising:
-
operating means for setting a divide point in a data file recorded in the data area;
editing means for editing, according to said divide point, the management data and an original attribute file corresponding to the data file wherein said divide point is set;
generating means for generating a new attribute file for designating a separate data file on a backward side of the divide point; and
recording means for recording the edited management data to the management area and recording the edited original attribute file to the data area. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
