方式にＪ、るスチルカメラが開光された。11j, s'f) In the case of a camera, the floppy disk can be further miniaturized by taking advantage of the usefulness of the floppy disk and the reusability of the recording medium, which is different from silver halide film using magnetic recording. ! (The diameter a5 and thickness of the disc-shaped recording medium have been further reduced, and along with this, the case to accommodate it has become smaller and the magnetic disk has been made harder.)
It was proposed to use a 1-car 1-ridge (also known as 1-car 1-ridge) as a recording medium for 11j cows, rotating at high speed, and to record the convexity of the conventional 35 mm t-shaped culm. A still camera was opened.

高密度記録が行なわれる。This Kerr 1 helicopter is placed in an extremely limited location within the body of the 35m camera culm 1.
One type of disk, such as a disk, which has a fitting hole in the center of the recording medium and is supported from both directions, is equipped with a hub that fits into the center of the recording medium and is inserted into the rotating shaft from one side. At the same time, recording media are formed thinly and have extremely low rigidity (1).On the other hand, in magnetic recording using such magnetic recording media, when recording bidet delta signals, digital signals and Since the frequency band of the video signal is much wider than that of the OEY signal, high-density recording is performed by rotating the recording medium at high speed and adjusting the relative speed between the recording medium and the magnetic head.

媒体は圧力を受ける。On the other hand, when a recording medium is rotated at a high speed, some parts of the recording medium rotate due to friction and spread out in a spiral shape from the center of the recording medium along the surface of the recording medium. The air flow applies pressure to the recording medium.

In this case, a stable contact state cannot be established between the magnetic head and the recording medium 1, and a good recording angle 1 cannot be obtained.

,stomach. (For ?J, "approximately silver-shaped" includes a spiral shape.) In the cars 1 to 2 of the present invention, the iM portion starting from the hub hole is approximately radial (on the inner surface of the bottom wall of the case). There is an air vent hole in the side chamber of the case.
When the recording medium is rotated at high speed, air flows in from the hub hole in the center of the case, flows stably into the groove, and is discharged from the side wall. In other words, the recording medium 1- is rotated four times around the central axis Yi in the direction perpendicular to the central axis 1 of the recording medium, and the air flow that covers it moves gradually away from the center of the medium in the direction 1''. The rotation of the air flow is suppressed by the grooves formed at a substantially right angle Ij to the direction of rotation of the air flow, and the air flow is smoothly guided in the outer peripheral direction of the recording medium to pass through an area corresponding to the C recording medium. Gatsu C recording medium?2
Even at high speeds, it can rotate smoothly to 7J- without flapping.

At this time, according to the movement of this air flow, air outside the car 1-ridge 11 enters through a gap formed between the outer periphery of the small diameter portion 10a of the hub 10 and the periphery of the huff hole 1 of the drying half 2. Is the air flow of this record 9-1 body 9-1- ζ in the groove part 3? The first resistor is applied to the groove 3, and the groove 3 moves toward the outer peripheral edge of the recording medium 9. Next, this record (reaching the outer edge of IM dedication!):
Air is discharged to the outside from a slit-shaped air vent hole 155 provided in the center of the side of the case. In this manner, when the recording medium 1 and 9 rotate, the air flow stably flows through the gap between the hub 9 and the huff hole 4, the groove 3, and the air vent hole 15 in the cullet 11.
