Fig. 1 shows an elevation and Fig. 2 illustrates a plan view of a contact or near contact transducer 5 for use with a flexible-type magnetic media. With the disk 6 moving in the direction of arrow A in Fig. 3 and a spring-loaded pressure pad 7 urging the disk toward transducer 5, the normal head design, that may include parallel longitudinal slots, develops an increasing positive pressure between transducer and media from the leading edge to the crest of the transducer surface. Simultaneously from the crest to the trailing edge the pressure drops rapidly to form a negative air pressure.
