Magnetic disk apparatus and head-supporting mechanism for the same
View Patent ↗A magnetic disk apparatus includes a magnetic disk on which information is stored, a magnetic head which performs writing-in and reading-out of information, a suspension which supports the magnetic head, and a suspension supporting member having a φ-shaped hinge. The suspension is supported at a tip end of the φ-shaped hinge and an actuator for moving the magnetic head to a predetermined position on the magnetic disk is disposed so as to bridge an open portion of the φ-shaped hinge. The actuator is coated with a resin material.
1. A magnetic disk apparatus comprising:
a magnetic disk on which information is stored;
a magnetic head which performs writing-in and reading-out of information;
a suspension which supports said magnetic head;
a suspension supporting member having a pair of outwardly protruding U-shaped arms, said suspension being supported by the pair of U-shaped arms; and
two actuator elements for moving said magnetic head to a predetermined position on said magnetic disk;
wherein said two actuator elements are disposed so as to connect said suspension with said suspension supporting member, and are coated with a resin material; and
wherein a shore D hardness of said resin material after curing is not greater than 80.
2. A magnetic disk apparatus comprising:
a magnetic disk on which information is stored;
a magnetic head which performs writing-in and reading-out of information;
a suspension which supports said magnetic head;
a suspension supporting member having a pair of U-shaped arms protruded outward, said suspension being supported by the pair of U-shaped arms; and
two actuator elements for moving said magnetic head to a predetermined position on said magnetic disk;
wherein said two actuator elements are disposed so as to connect said suspension with said suspension supporting member, and are coated with a resin material; and,
wherein an elastic modulus of said resin material after curing is not greater than 1000 MPa.
