Abstract

PURPOSE:To achieve the most suited distance between magnetic poles surely and stably, by jetting a high pressure air from the tip of an auxiliary magnetic pole. CONSTITUTION:A high pressure air 14 is introduced to an air jetting path 11 as the arrow and jetted from the tip of a cylinder 10. As a result, a magnetic recording medium 1 is pushed on a main magnetic pole 2 with the air 14 and both are closely adhered. The cylinder 10 is pushed up toward the arrow F1, that is, the opposite direction as the main magnetic pole 2. The thickness of air layer caused between an auxiliary magnetic pole 8 and a magnetic recording medium 1 can be kept constant by producing a force F2 balanced with the pushing-up force F1 by a plate spring 13, allowing to keep the most suited pole distance between the poles 8 and 2.
