Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To obtain a helical scan type magnetic recording/reproducing apparatus having high recording density.
SOLUTION: In the helical scan type magnetic recording/reproducing apparatus in which input data are encoded and recorded by recording heads W1-W4 as signals of n system (e.g. n=4), reproduced by 2n pieces of reproduction heads R1-R8 and subjected to non-tracking process to decode them, each of the recording heads W1-W4 is constituted as one head having four multi-gaps with lower magnetic poles 31 and upper magnetic poles 33 arranged thereon through a gap 32. Core widths CW of the recording heads W2, W3, W4 are each made to be a track pitch TP +α1 and formed to be overlapped with the track pitch TP of the W1-W3 by α1, so that the specified recording width TP can be surely obtained, and the core width CW of the W1 is formed into the track pitch TP +α2 (α2>α1) while taking the fluctuation of the head position one round after into account, then the recording pattern without gap is obtained.

Abstract: PROBLEM TO BE SOLVED: To make constructible a high-density recording system by forming a magnetic layer on a nonmagnetic supporting body, and setting the product of the amount of residual magnetization and the film thickness of the magnetic layer, and the track pitch of recording tracks formed to the magnetic layer in a specific range. SOLUTION: The magnetic layer 2 of a metallic magnetic thin film is formed on a nonmagnetic supporting body 1, thereby constituting the magnetic recording medium. In the magnetic recording medium, the product Mr.t of the amount of residual magnetization Mr and the film thickness(t) of the magnetic layer is set to be 0.5-3.0 memu/cm2 and, the track pitch of recording tracks formed to the magnetic layer is set to be 1-5 μm. At this time, the thickness of the magnetic layer 2 can be controlled by changing a line speed in a thin film form apparatus, and the amount of residual magnetization can be controlled by changing an amount of oxygen introduced during the film formation. The product of the amount of residual magnetization and film thickness of the magnetic layer is specified by controlling the two parameters desirably.

Abstract: PROBLEM TO BE SOLVED: To clarify the position of a magnetic tape at the time of recording or reproducing by performing tracking control of a magnetic field applying means or a magnetic field detecting means on the basis of a tracking signal, and bringing a magnetic head almost exactly on the prescribed position of a recording track at the time of recording an information signal. SOLUTION: A tracking signal is recorded in a block almost at the center of recording tracks TA1, TA2, TA3, a reproduced signal from a reproducing magnetic head is supplied to a circuit for tracking control, and tracking control is performed for this reproducing magnetic head. Thereby, the reproducing magnetic head scans almost exactly over the block almost at the center of the recording tracks TA1, TA2, TA3. Also, another reproducing magnetic head scans a magnetic tape 7 in the same way. In this case, the two reproducing magnetic heads scan respectively places separated by one track pitch. Thus, a magnetic tape is scanned with double density using a plurality of reproducing magnetic heads.
