PROBLEM TO BE SOLVED: To edit video/audio image quality enhanced or sound quality enhanced data without performing overwrite since data enormously increase as video/audio image quality/sound quality is enhanced, a track width becomes extremely narrow even in a helical tape recording system and overwrite onto a certain specific track is physically disabled in a conventional editing method. SOLUTION: An HDD 28 capable of current large-capacity and high-speed transfer is used to perform video/audio editing on the HDD 28 without compressing data, and all the data regarded necessary for editing are pumped up from a tape storage 24 capable of large-capacity and high-speed transfer and high-speed access to the HDD 28 to perform video/audio editing. Namely, a portion desired to edit is temporarily copied onto an editing medium 25 of the tape storage 24 built in an apparatus, and edited using an HDD 28 + PC 29 of an external editing system 31 and editing data 33 are then copied onto an original master tape 25, so that "overwrite" on a "defective position is not performed. Thus, accurate frame position detection or time required therefor is obviated, thereby performing speedy editing work. COPYRIGHT: (C)2005,JPO&NCIPI
