Abstract
Abstract A device and method for editing a signal recorded on a magnetic disk. An image signal recorded on a first track of the disk is stored in a first memory, and then the signal of the first track is erased. An image signal recorded on a second track of the disk is stored in a second memory, and then the signal of the second track is erased. The signal stored in the first memory is recorded on the second track, and then the signal stored in the second memory is recorded on the first track.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
181 words
A device for editing signals recorded in recording areas of a recording medium used for a still video device, said device comprising: a first memory in which a signal which is recorded in one recording area of said recording medium can be stored; a second memory in which a signal which is recorded in another recording area of said recording medium can be stored during the same time which the signal, in said first memory is stored; means for storing a signal recorded in a first recording area of said recording medium in said first memory, and for storing a signal recorded in a second recording area of said recording medium in said second memory while said signal from said first recording area remains stored in said first memory; means for erasing the signal recorded in said first recording area, after said storing means stores the signals in said first and second memories; and means for reading the signal recorded in said second memory so that the signal recorded in said second memory can be recorded in said first recording area.
Claim 2
Independent Claim
181 words
A device for editing signals recorded in recording areas of a recording medium used for a still video device, said device comprising: a first memory in which a signal which is recorded in one recording area of said recording medium can be stored; a second memory in which a signal which is recorded in another recording area of said recording medium can be stored during the same time which the signal, in said first memory is stored; means for storing a signal recorded in a first recording area of said recording medium in said first memory, and for storing a signal recorded in a second recording area of said recording medium in said second memory while said signal from said first recording area remains stored in said first memory; means for erasing the signal recorded in said first recording area, after said storing means stores the signals in said first and second memories; and means for reading the signal recorded in said second memory so that the signal recorded in said second memory can be recorded in said first recording area.
Claim 3
Dependent Claim
12 words
A device according to claim 1, wherein the signals comprise image signals.
Claim 4
Dependent Claim
35 words
A device according to claim 1, further comprising means for sensing a recording state in which a signal has been recorded on said recording medium before an editing operation is carried out by said device.
Claim 5
Dependent Claim
26 words
A device according to claim 3, wherein said sensing means sense whether or not a signal is recorded in a recording area of said recording medium.
Claim 6
Dependent Claim
26 words
A device according to claim 3, wherein said sensing means sense whether the signal is recorded in a frame record mode or a field record mode.
Claim 7
Dependent Claim
54 words
A device according to claim 5, wherein, when said sensing means sense that the signal is recorded in the frame record mode, said sensing means assumes that another signal forming a pair with the first signal is recorded in a recording area adjacent to the recording area in which the first signal is recorded.
Claim 8
Dependent Claim
20 words
A device according to claim 3, wherein said sensing means sense whether or not a signal is an audio signal.
Claim 9
Dependent Claim
29 words
A device according to claim 7, further comprising means for outputting an alarm when said sensing means sense that an audio signal has been recorded on said recording medium.
Claim 10
Dependent Claim
32 words
A device according to claim 3, wherein said sensing means sense the number of recording areas in which no signal is recorded before an editing operation is carried out by said device.
Claim 11
Dependent Claim
45 words
A device according to claim 1, further comprising means for determining, after an editing operation is carried out by said device, but before said signal is recorded in said first recording area, a recording state in which a signal is recorded on said recording medium.
Claim 12
Dependent Claim
39 words
A device according to claim 10, further comprising means for preventing one signal recorded in a recording area of said recording medium before the editing operation, from being recorded in a plurality of recording areas of said recording medium.
Claim 13
Dependent Claim
46 words
A device according to claim 10, further comprising means for outputting an alarm when said determining means determine that the number of non-recorded areas which would exist, after performance of the editing operation, exceeds the number of non-recorded areas which exist before completing the editing operation.
Claim 14
Dependent Claim
56 words
A device according to claim 10, wherein, when said determining means determine that the signal is recorded in the frame record mode, said determining means also determine that the other signal forming a pair with the first signal is recorded in a recording area adjacent to the recording area in which the first signal is recorded.
Claim 15
Dependent Claim
51 words
A device according to claim 10, further comprising means for outputting an alarm when said determining means determine, after editing but before recording, that a signal would be recorded in an undesirable manner, in a recording state determined by said determining means, with respect to signal recordings before the editing operation.
Claim 16
Dependent Claim
52 words
A device according to claim 10, further comprising means for outputting an alarm when said determining means determine that a signal which has already been recorded in a recording area of the recording medium by an editing operation has been assigned to be recorded in another recording area of the recording medium.
Claim 17
Dependent Claim
149 words
A still video editing device comprising: a first memory in which an image signal recorded on one track of a disk can be stored; a second memory in which an image signal recorded on another track of the disk can be stored during the time which said first memory stores an image signal; means for storing an image signal recorded on a first track of the disk in one of said memories, and storing an image signal recorded on a second track of the disk in the other of said memories; means for erasing at least one image signal recorded on said first and second tracks, after said storing means stores the image signals in said memories; and means for reading the image signal to be recorded on another track from the memory and recording the image signal on the track from which the image signal has been erased.
Claim 18
Dependent Claim
149 words
A still video editing device comprising: a first memory in which an image signal recorded on one track of a disk can be stored; a second memory in which an image signal recorded on another track of the disk can be stored during the time which said first memory stores an image signal; means for storing an image signal recorded on a first track of the disk in one of said memories, and storing an image signal recorded on a second track of the disk in the other of said memories; means for erasing at least one image signal recorded on said first and second tracks, after said storing means stores the image signals in said memories; and means for reading the image signal to be recorded on another track from the memory and recording the image signal on the track from which the image signal has been erased.
