Abstract

Assemblies in accordance with the present invention can access a data storage medium having one or more disks (120). One such assembly comprises a mounting block (250) including a bore (252) and at least one arm connected with the mounting block. A flexible member is connected with the at least one arm (136) and a head is associated with the flexible member (142). The head is positioned over the surface of the disk. The arm is designed such that it can be disconnected from the mount without disassembling the bore. By having a removably fastened arm, the assembly can be built at a relatively low cost and without misalignment and deformation. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
