ABSTRACT:
In a magnetic transducer assembly for magnetic recording disks, a magnetic slider body has two laterally spaced apart longitudinal rails each having a floating surface and a groove formed between them. A thin-film magnetic core assembly is mounted on an end wall of each of the rails and a magnetic gap is formed on each floating surface. A suspension element has one end secured to the bottom surface of the groove for maintaining the slider assembly in a constant position with respect to the surface of the disk. Preferably, the longitudinal rails are bridged bya laterally extending block to create negative pressure between the rails by relative movement between the assembly and the surface of the disk, and the suspension element exerts pressure in a direction away from the surface of the disk.
