ABSTRACT:
Described herein are various embodiments of an electronic information storage apparatus and an associated method and system. For example, according to one illustrative embodiment, a disk drive comprises a base and at least one disk that are rotatably attached to the base. The at least one disk can include a burnished and lubricant-free outer surface. The disk drive can also include an actuator coupled to the base. The actuator can comprise a read/write head that is positionable in a reading/writing relationship with the at least one disk to define a lubricant-free space intermediate the read/write head and the outer surface. The disk drive can further include a read/write head loading and unloading ramp that is attached to the base. The ramp can include a ramp surface that is positioned proximate a periphery of the at least one disk.
