A tape floating type video cylinder named MAF (Micro Air Float) is proposed. This cylinder has spiral grooves with a pump-out effect at the bottom of the upper cylinder. The characteristics of the pump-out pressure of an MAF cylinder are theoretically formulated, and the results agree with the experimental data. Tape floating on the cylinder is measured dynamically with the optical sensor and compared with the normal (groove-less) type cylinder, and it becomes clear that the pressure from the spiral grooves is effective for tape floating, especially at the lower cylinder. The mechanism of tape floating on the cylinder with spiral grooves is discussed, and it is found that the radius difference between the upper and the lower cylinder effects the tape floating.
