Claims

[Scope of utility model registration request]

a rotating mechanism for a magnetic disk; and a first disk for recording or reproducing signals by slidingly contacting one surface of the disk.
a first head carriage to which the first magnetic head is attached and which is movable in the radial direction of the disk; a second magnetic head that records or reproduces a signal by slidingly contacting a surface; a second head carriage to which the second magnetic head is attached; and a second head carriage that is connected to the first head carriage. A magnetic disk device comprising a leaf spring having a spring hinge function for attachment, and a mechanism for moving the first and second head carriages in the radial direction of the disk,
A magnetic disk device characterized in that the plate spring is coated with a viscoelastic material for damping resonance.
