Disclosed is a continuous separator plate for use with a disk drive. The continuous separator plate includes a substantially circular continuous outer circumference and a substantially circular continuous inner circumference. A continuous radial portion may be defined between the substantially circular continuous outer and inner circumferences. The continuous radial portion is to be disposed between at least one disk of the disk drive and either the cover or the base of the disk drive, respectively. Further, the continuous radial portion includes a disk side that faces the at least one disk and an opposite side that faces either the cover or the base, respectively. The continuous separator plate further includes a head stack assembly (HSA) accommodation section to accommodate an HSA.
