Video tape player for displaying a previously recorded video signal read from a magnetic tape during high speed recording of an externally supplied video signal |
摘要 |
A video cassette recorder (VCR) is disclosed which is capable of displaying the video being erased during a recording operation. Thus, during a recording operation the user is able to monitor the video being erased, so as to stop recording if the VCR has reached a video the user wishes to preserve. The VCR is capable to display the video being erased during a recording operation by doubling the rotational speed of the head cylinder during a recording operation. Since the rotational speed is doubled, half of the time period is used for reading and half for recording. The VCR includes a decompressing circuit to restore the video read during the double speed rotation of the head cylinder, and also includes a compressor to compressed the externally supplied video so as to record that signal at double the normal rotational speed.
