Abstract: A pattern is recorded on a magnetic medium by passing the medium across a master rotary element having a predetermined pattern of magnetic and nonmagnetic areas. A first magnetic heat magnetizes the medium in a first direction, and a second head that provides a constant DC field then selectively magnetizes the medium in a different direction in those locations where the magnetic areas of the patterned rotary element do not shield the medium from the field.
Abstract translation: 通过使介质穿过具有预定图案的磁性和非磁性区域的主旋转元件，将图案记录在磁性介质上。 第一磁性热在第一方向上磁化介质，并且提供恒定DC场的第二磁头然后在图案化旋转元件的磁性区域不将介质遮蔽的位置沿不同方向选择性地磁化介质 领域。

Abstract: THIS INVENTION TEACHES AN ASSEMBLY FOR HOLDING A TRANSDUCER-CARRYING T-SHAPED SLIDER IN COMPLIANCE WITH A MOVING MAGNETIC MEDIUM. THE ASSEMBLY COMPRISES A SUSPENSION SYSTEM INCLUDING A FLEXURE SUPPORTING THE SLIDER FOR ALLOWING THE SLIDER TO HAVE FREEDOM IN PITCH AND ROLL AND MAINTAINING THE SLIDER IN A CONSTANT YAW POSITION, AND A FLEXIBLE SUPPORTING STRUCTURE JOINED TO THE FLEXURE. THE SUPPORTING STRUCTURE BECOMES STIFF IN THE DIRECTION OF ACCESS UNDER LOAD.
