A carriage assembly for carrying read/write heads into engagement with a recording medium is provided. The carriage assembly includes a carriage body that defines a sidewall having a first opening and a second opening with a passage extending therebetween. A coil is securely coupled with the carriage body sidewall. The carriage assembly rides on a central guide track when the carriage assembly is mounted within a disk drive. The carriage assembly is free to rotate about the central guide track. A first in-rigger extends laterally from the carriage body and a second in-rigger extends laterally from the carriage body. Each of the in-riggers has a protrusion extending from an inner surface. If the carriage assembly rotates sufficiently in one direction one of the protrusions will contact a magnet of the disk drive to prevent further rotation of the carriage assembly in that direction. Similarly, if the carriage assembly is rotated in the opposite direction, the other protrusion will contact the magnet to prevent rotation of the carriage assembly in the opposing direction. The in-riggers thereby maintain the carriage assembly centered on the central guide track.
