Abstract
A disk apparatus includes a carriage, a magnetic disk, a base plate, a load beam, a flexure, and a magnetic head. The carriage rotates around a first rotation axis. The base plate includes a first surface facing the magnetic disk and is attached to the carriage. The load beam is attached to the base plate. The flexure includes a plurality of wirings and is attached to the base plate and the load beam. The magnetic head is attached to the flexure and electrically connected to at least one of the plurality of wirings. The flexure includes a thin portion that is thinner than other portions of the flexure. The thin portion includes a first portion which covers the first surface and at which the plurality of wirings extends in non-parallel directions with respect to each other.
Claims20
A disk apparatus comprising:
- a carriage configured to rotate around a first rotation axis;
- a magnetic disk;
- a base plate attached to the carriage and including a first surface that faces the magnetic disk;
- a load beam attached to the base plate;
- a flexure including a plurality of wirings and attached to the base plate and the load beam;
- and
- a magnetic head attached to the flexure, electrically connected to at least one of the plurality of wirings, and configured to write and read information to and from the magnetic disk,
- the flexure including a thin portion, the thin portion being thinner than other portions of the flexure, and
- the thin portion including a first portion that covers the first surface of the base plate and includes at least two of the plurality of wirings, wherein the two wirings of the first portion are non-parallel.
A disk apparatus comprising:
- a carriage configured to rotate around a first rotation axis;
- a magnetic disk configured to rotate around a second rotation axis separated from the first rotation axis;
- a base plate attached to the carriage and including a first surface that faces the magnetic disk;
- a load beam attached to the base plate and including a second surface that faces the magnetic disk;
- a flexure including
- a first portion covering the first surface,
- a second portion covering the second surface,
- a first thin portion extending between the first portion and the second portion and crossing an edge of the second surface, and
- a second thin portion farther from the second rotation axis than the base plate,
- wherein each of the first thin portion and the second thin portion is thinner than each of the first portion and the second portion;
- and
- a magnetic head attached to the second portion and configured to write and read information to and from the magnetic disk.
A disk apparatus comprising:
- a carriage including a plurality of arms and configured to rotate around a first rotation axis;
- a magnetic disk;
- a suspension attached to one of the arms and including a base plate, a load beam attached to the base plate, and a flexure having wires and attached to the base plate and the load beam, the flexure comprising a main body and a suspension tail;
- and
- a magnetic head attached to the flexure, electrically connected to the wires, and configured to write and read information to and from the magnetic disk, wherein
- the flexure has one or more first portions and one or more second portions along the length thereof, the first portion having a thickness that is equal to or less than half of a thickness of the second portion,
- at least one of the one or more first portions and at least one of the one or more second portions are provided in the main body and cover a surface region of the base plate that faces the magnetic disk, and
- the wires are non-parallel at some locations of the flexure and include a read wiring for transmitting a read signal from the magnetic head and a write wiring for transmitting a write signal to the magnetic head.
