Systems and methods are disclosed for resource allocation for multi-actuator systems. In some examples, a data storage device can include two or more independently moveable voice coil motor (VCM) actuators where the resources of the system to operate the VCM actuators are divided. The disclosure here describes methods to allocate or re-allocate the divided resources, such as unused resources, to a VCM actuator that has a need for more resources. The methods and systems herein can also be applied to other actuator systems.

Resource allocation for multi-actuator storage device

A method for scheduling data transfer commands between a first actuator or a second actuator across an interface is disclosed. The method includes balancing data transfer commands between the first actuator and the second actuator by applying a first rule for read commands and a second rule for write commands.
