A disk drive with DTR media and method of assembly is described. The method may include aligning a discrete track recording (DTR) track pattern center on a DTR disk with a rotational center of a spindle hub and mounting the DTR disk on the spindle hub to minimize eccentricity. After the DTR disk is mounted to the spindle hub, it may be rotated to a designed rotational speed and the mass imbalance of the rotating DTR disk/spindle hub may be measured. The mass imbalance may be mitigated using a mechanical component such as a counter weight coupled to a spindle rotatable component, for example, the spindle hub, a spacer assembly, a clamp assembly, etc. The method may mitigate the eccentricity associated with DTR media and minimize run-out due to the mass imbalance of an otherwise rotated DTR disk/hub aligned for eccentricity correction.
