Abstract
Abstract A recording device for an electronic still camera in which, even in the case where, in a recording mode in which video signals and compressed audio signals are recorded in pairs, an audio signal is not recorded after the recording of a video signal and another video signal is recorded immediately thereafter, the recording operation can be achieved readily and the signal recording or reproducing operation can be started quickly. In accordance with the invention a control unit, in response to a video signal recording instruction, operates to record a video signal on a track which is removed by a two-track pitch in one direction from the track where the preceding video signal has been recorded, and, in response to an audio signal recording instruction, operates to record a compressed audio signal on a track which is removed by a one-track pitch in the same direction from the track where the preceding video signal has been recorded.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A recording device for an electronic still camera, comprising: control means; recording drive means controlled by said control means to move a recording head by a predetermined track pitch; a video/audio change-over switch controlled by said control means to selectively supply a video signal or time-compressed audio signal to said recording head so that video signals and compressed audio signals are recorded on a memory disc with said recording head; a video signal recording switch for inputting a video signal recording instruction; and an audio signal recording switch for inputting an audio signal recording instruction, said control means, in response to said video signal recording instruction, operating to record a video signal on a first track, and, in response to said audio signal recording instruction, operating to record a time-compressed audio signal on a track which is removed by a one-track pitch in one direction from said first track, said video signal and audio signal being recorded on said memory disc alternately.
Claim 2
Dependent Claim
162 words
A recording device for an electronic still camera, comprising: control means; recording drive means controlled by said control means to move a recording head by a predetermined track pitch; a video/audio change-over switch controlled by said control means to selectively supply a video signal or time-compressed audio signal to said recording head so that video signals and compressed audio signals are recorded on a memory disc with said recording head; a video signal recording switch for inputting a video signal recording instruction; and an audio signal recording switch for inputting an audio signal recording instruction, said control means, in response to said video signal recording instruction, operating to record a video signal on a first track, and, in response to said audio signal recording instruction, operating to record a time-compressed audio signal on a track which is removed by a one-track pitch in one direction from said first track, said video signal and audio signal being recorded on said memory disc alternately.
Claim 3
Dependent Claim
250 words
A recording device for an electronic still camera comprising: control means; recording head drive means controlled by said control means for moving a recording head by a predetermined track pitch; a video/audio change-over switch controlled by said control means for selectively supplying a video signal or time-compressed audio signal to said recording head so that video signals and time-compressed audio signals are recorded on a memory disc with said recording head; a video signal recording switch for inputting a video signal recording instruction; and an audio signal recording switch for inuptting an audio signal recording instruction; said recording head comprising first and second head elements which face two adjacent tracks simultaneously, said control means, in response to said video signal recording instruction, causing said first head element to record said video signal on a memory disc and then moving said recording head by a one-track pitch towards said second head element, and, in response to said audio signal recording instruction, causing said first head element to record said audio signal on said memory disc and then moving said recording head by a one-track pitch toward said second head element, and in the case where the preceding instruction is said audio signal recording instruction, causing said first head element to record a video signal on said memory disc and then moving said recording head by a one-track pitch towards said second head element, whereby video signal recording tracks and time-compressed audio signal recording tracks are arranged alternately on said memory disc.
Claim 4
Dependent Claim
250 words
A recording device for an electronic still camera comprising: control means; recording head drive means controlled by said control means for moving a recording head by a predetermined track pitch; a video/audio change-over switch controlled by said control means for selectively supplying a video signal or time-compressed audio signal to said recording head so that video signals and time-compressed audio signals are recorded on a memory disc with said recording head; a video signal recording switch for inputting a video signal recording instruction; and an audio signal recording switch for inuptting an audio signal recording instruction; said recording head comprising first and second head elements which face two adjacent tracks simultaneously, said control means, in response to said video signal recording instruction, causing said first head element to record said video signal on a memory disc and then moving said recording head by a one-track pitch towards said second head element, and, in response to said audio signal recording instruction, causing said first head element to record said audio signal on said memory disc and then moving said recording head by a one-track pitch toward said second head element, and in the case where the preceding instruction is said audio signal recording instruction, causing said first head element to record a video signal on said memory disc and then moving said recording head by a one-track pitch towards said second head element, whereby video signal recording tracks and time-compressed audio signal recording tracks are arranged alternately on said memory disc.
Claim 5
Dependent Claim

A recording method for an electronic still camera, comprising the steps of: recording, in response to a video signal recording instruction, a video signal on a track which is removed by a two-track pitch in one direction from the track where a preceding video signal has been recorded; and, in response to an audio signal recording instruction, recording a compressed audio signal on a track which is removed by a one-track pitch in the same direction from said track where the preceding video signal was recorded.
Claim 6
Dependent Claim
86 words
A recording method for an electronic still camera, comprising the steps of: recording, in response to a video signal recording instruction, a video signal on a track which is removed by a two-track pitch in one direction from the track where a preceding video signal has been recorded; and, in response to an audio signal recording instruction, recording a compressed audio signal on a track which is removed by a one-track pitch in the same direction from said track where the preceding video signal was recorded.
Claim 7
Dependent Claim
