Contact-type magnetic head having an integral control portion for
generating negative pressure
摘要:
A magnetic head having a control portion provided integrally with an opposing surface located opposing the recording surface of a magnetic disc or a head mount for generating a negative pressure between the control portion and the magnetic disc to attract the magnetic disc towards the magnetic head, thereby generating an adequate and sufficient negative pressure in the vicinity of the magnetic head and achieving a good head touch. This configuration enables compact design of the mechanism and an increased recording area of the magnetic disc compared with the case in which a magnetic head and a negative pressure generation type stabilizing plate to attract the magnetic disc towards the magnetic head are separately disposed, and eliminates the need for procedures for separate positioning of the individual magnetic head and stabilizing plate, thereby achieving a considerable reduction in manufacturing steps and production cost.
