OVERVIEW
USAGE EXAMPLES
For making business reports
The working process can be easily recorded on a disk.
Filing data is also easy, as film development is not required.

RECORDING FORMAT OF A STILL VIDEO CAMERA RECORDER
This unit conforms to the Video/Audio Recoding Format of the Still Video Floppy System and can
record video signals of 525 lines and 60 fields, and audio signals of 5 kHz for 10 seconds per track.
This unit is for recording only. Playback, erasing and editing are not possible on this unit. For playback,
erasing and editing the recordings, use the Sony MVR-A770 still video recorder.
The still video floppy disk
A still video floppy disk has 52 tracks numbered from the outer rim in. Tracks 1 through 50 are assigned
for video and audio recordings, while track 51 is unused. Track 52 is assigned for cue recording, but
cannot be used because this unit does not conform to the Data and Cue Signal Formats. The recording
head moves linearly radius toward the center along the radius as the disk rotates.
Recording side
Video recording
A disk can hold 25 frame recordings, which
require 2 tracks a piece, or 50 field recordings,
which require 1 track a piece.
The picture quality of the field recording is
slightly inferior to that of the frame recording,
while the sensitivity of the field recording
(equivalent to ISO 80) is superior to that of the
frame recording (equivalent to ISO 160).
Continuous video and audio recording
An audio recording for 9.6 seconds can be
automatically activated immediately following a
video recording. For consecutive video and audio
recordings, 3 tracks are required in the frame
mode, and 2 tracks in the field mode.
Audio recording
The Video/Audio Recording Format specifies 3
audio recording Formats: 5-second (10 kHz),
10-second (5 kHz) and 20-second (2.5 kHz)
recordings on a track. This unit employs the
audio recording format for 10 seconds (actually
9.6 seconds) on a track, thus a disk can hold up
to 480 seconds of audio recordings.
