A disk drive includes an enclosure that defines an exterior surface, the enclosure including a base, a cover and a hinge mechanically coupling the base to the cover such that the hinge forms a portion of the exterior surface of the enclosure. A spindle motor is attached to the base, a disk is mounted to the spindle motor, and a head stack assembly is pivotally coupled to the base. A method of manufacturing a disk drive includes a single (injection, for example) molding step to form an enclosure including the base, the cover and a hinge that mechanically couples the base to the cover such that the hinge forms a portion of the exterior surface of the enclosure. The spindle motor may then be attached to the base, the disk or disks mounted to the spindle motor and the head stack assembly may be pivotally coupled to the base. Alternatively, the base and the cover may be separately provided and the hinge may be molded (by an insert molding process, for example) onto the base and the cover to mechanically couple the base to the cover such that the hinge again forms a portion of the exterior surface of the enclosure.

The method of disk drive system operation as claimed in claim 1 wherein the step of providing data layout mapping includes the step of: mapping logically adjacent data blocks: to the data track, then to the radially-adjacent data track on the same surface in a first direction in the data track set in the bunch, then to the different data track in the different data track set in the bunch, and then to the radially-adjacent data track on the different surface in a second direction in the different data track set in the bunch. 4. The method of disk drive system operation as claimed in claim 1 wherein the step of providing data layout mapping includes the step of: mapping logically adjacent data blocks: to the last track of a bunch on its surface, and then to the first track of a different bunch on a different surface. 5. The method of disk drive system operation as claimed in claim 1 wherein the step of providing data layout mapping includes the steps of: mapping logically adjacent data blocks: to the last track of a bunch on its surface, and then to the first track of a different bunch on the same surface. 6. The method of disk drive system operation as claimed in claim 1 including the step of: providing a surface with a plurality of concentric, circular data tracks. 7. The method of disk drive system operation as claimed in claim 1 including the step of: providing a surface with a plurality of radially-adjacent data tracks connected into a spiral. 8. The method of disk drive system operation as claimed in claim 1 wherein the step of providing data layout mapping includes the step of: changing the data layout mapping during disk drive system operation. 9. The method of disk drive system operation as claimed in claim 1 wherein the step of providing data layout mapping includes the step of: providing a plurality of different numbers of data tracks gathered into a data track set. 10. A method of disk drive system operation for a disk drive system having a plurality of surfaces for storing data blocks, each surface having a plurality of data tracks for storing the data blocks, comprising the steps of: grouping data tracks on a surface into a plurality of data track sets; grouping data track sets on different surfaces into a plurality of bunches; and providing a data layout mapping that maps logically adjacent data blocks: to a data track on a first surface, to a radially-adjacent data track on the first surface in a data track set in a bunch when the data track is filled, to a different data track on a second surface in a different data track set in the bunch when the data track set is filled, and from a first data track in a cylinder in the bunch to a second data track radially-adjacent to the first data track in a cylinder in a different bunch. 11. The method of disk drive system operation as claimed in claim 10 wherein the step of providing a data layout mapping includes the step of: mapping logically adjacent data blocks: to a first data track on the first surface in a first data track set, then, when the first data track is filled, to the radially-adjacent data track in the inward direction on the same first surface in the same first data track set, then, when the first data track set is filled, to a different data track in a different data track set, and then, when the different data track in the second data track set is filled, to an radially-adjacent data track in the inward direction on the second surface in the different data track set. 12. The method of disk drive system operation as claimed in claim 10 wherein the step of providing data layout mapping in
