Suspension assembly and disk device
View Patent ↗According to one embodiment, a suspension assembly includes a support plate, a wiring member disposed on the support plate, and a head supported on the support plate through the wiring member. The wiring member includes a distal end portion electrically connected to the head, a connection end portion extending outside the support plate, and a plurality of wirings extending between the distal end portion and the connection end portion. The connection end portion includes an opening with predetermined length and width and thirteen or more connection terminals disposed in the opening and arranged at intervals in a direction of the length. A percentage of an area of the opening occupied by areas of the thirteen or more connection terminals is 40% to 65% inclusive.

2. The suspension assembly of claim 1 , wherein
the connection end portion comprises fourteen or more connection terminals disposed in the opening and the sum of the areas of the fourteen or more connection terminals occupies 47% or more of the area of the opening.
3. The suspension assembly of claim 1 , wherein
the thirteen or more connection terminals include connection terminals for a write head, connection terminals for a read head, connection terminals for an assisting element, connection terminals for a heater, connection terminals for an HDI sensor, and connection terminals for a micro-actuator,
the connection terminals for the HDI sensor or the connection terminals for the heater are disposed between the connection terminals for the assisting element and the connection terminals for the read head, and
the connection terminals for the HDI sensor or the connection terminals for the heater are disposed between the connection terminals for the assisting element and the connection terminals for the write head.
4. The suspension assembly of claim 1 , wherein
the thirteen or more connection terminals are arranged such that intervals between the connection terminals positioned at one end portion in the direction of the length of the opening are narrower than intervals between the connection terminals positioned at a central portion in the direction of the length of the opening.
5. The suspension assembly of claim 1 , wherein
the thirteen or more connection terminals are arranged such that intervals between the connection terminals positioned at one end portion in the direction of the length of the opening are narrower than intervals between the other connection terminals.
6. The suspension assembly of claim 1 , wherein
a width of the connection terminal positioned at an end portion in the direction of the length of the opening is larger than a width of the connection terminal positioned at a central portion in the direction of the length of the opening.
7. The suspension assembly of claim 1 , wherein
a width of the connection terminal positioned at one end portion in the direction of the length of the opening is larger than a width of the other connection terminals.
8. A disk device comprising:
a disk-shaped recording medium; and
the suspension assembly of claim 1 .
9. The disk device of claim 8 , wherein
the connection end portion comprises fourteen or more connection terminals disposed in the opening and the sum of the areas of the fourteen or more connection terminals occupies 47% or more of the area of the opening.
10. The disk device of claim 8 , wherein
the thirteen or more connection terminals include connection terminals for a write head, connection terminals for a read head, connection terminals for an assisting element, connection terminals for a heater, connection terminals for an HDI sensor, and connection terminals for a micro-actuator,
the connection terminals for the HDI sensor or the connection terminals for the heater are disposed between the connection terminals for the assisting element and the connection terminals for the read head, and
the connection terminals for the HDI sensor or the connection terminals for the heater are disposed between the connection terminals for the assisting element and the connection terminals for the write head.
11. The disk device of claim 8 , wherein
the thirteen or more connection terminals are arranged such that intervals between the connection terminals positioned at one end portion in the direction of the length of the opening are narrower than intervals between the connection terminals positioned at a central portion in the direction of the length of the opening.
12. The disk device of claim 8 , wherein
the thirteen or more connection terminals are arranged such that intervals between the connection terminals positioned at one end portion in the direction of the length of the opening are narrower than intervals between the other connection terminals.
13. The disk device of claim 8 , wherein
a width of the connection terminal positioned at an end portion in the direction of the length of the opening is larger than a width of the connection terminal positioned at a central portion in the direction of the length of the opening.
14. The disk device of claim 8 , wherein
a width of the connection terminal positioned at one end portion in the direction of the length of the opening is larger than a width of the other connection terminals.
