Abstract:
1. A disk drive, comprising: a disk drive cover including an top surface separated from an upper disk surface of said disk drive by essentially a first gap; a disk drive base including a bottom surface separated from a lower disk surface of said disk drive by essentially a second gap; and a disk containing each member of a disk surface collection comprising said upper disk surface and said lower disk surface; wherein all of said disk surface collection members rotate at an operating rotational velocity; wherein rotation of said disk surface collection member at said operating rotational velocity corresponds to a boundary layer thickness from said disk surface collection members, for each of said disk surface collection members; wherein said disk drive cover further includes a second top surface region formed to facilitate the motion of an actuator arm between said disk cover and said upper disk surface; wherein said operating rotational velocity is at least 5400 revolutions per minute; wherein said gap collection is comprised of said first gap and said second gap; wherein said disk drive has a height of at most 13 millimeters; wherein said gap collection member is at most three quarters of said boundary layer thickness.
