Magnetic disk device

Abstract

Abstract PURPOSE:To prevent excitation due to the mechanical reaction of a carriage constituting body on a magnetic disk at the time of driving access from being generated, by arranging a magnetic circuit which constitutes a head positioner, in a housing via an vibration damping means. CONSTITUTION:The magnetic circuit 31 consisting of a magnet 31a and a yoke 31b, etc., which performs the driving access of two carriage constituting bodies 18 and 19 is provided with the entrances and exits of the constituting bodies 18 and 19, and is supported and fixed in a state where it is suspended in a space in the housing 20 arranged on a base body 22 via shearing dampers 32 in the upper and lower spaces and elastic parts 33 consisting of leaf springs in the periphery. Thereby, it is possible to prevent the reaction generated in the driving of the constituting bodies 18 and 19 from being transmitted to a magnetic disk via a spindle, and also, to eliminate mutual interference in vibration, and to improve the positioning accuracy of a head by a multi-position system.
