Abstract
Disclosed are methods and assemblies used to optically communicate signals within a hard disk drive between controller electronics and recording heads. One or more transceivers in a fixed location can be used to communicate with one or more transceivers positioned on a moveable actuator and coupled to the recording heads. The use of linear motion actuators can help preserve line-of-sight optical communication between the transceivers.
