Abstract

PURPOSE:To form an air film and to run a tape stably, by making the extent of depression of a rotary disk between an upper and a lower drum slight, and making the intervals of the circumferential parts of both the drums less than the bottom width of a tent. CONSTITUTION:The extent (c) of depression of a rotary disk 2'' provided between an upper drum and a lower drum 3 and having a magnetic head 4 projecting from both the drums is set slight, and the width of the rotary disk 2'', namely, the interval (d) of the circumferential parts of the drums 1 and 3 is made less than the bottom width (b) of a tent formed by raising a tape in a tent shape by the magnetic head 4. Consequently, an air film is formed to achieve a stable tape run with less tape damage and less head wear.
