Abstract
Narrow gaps near the end of travel of a linear actuator coil of a magnetic disk drive is disclosed. The gaps are formed between actuator magnets and inner return path members on opposing sides of an actuator carriage. The narrow gaps are formed by protrusions on the inner return path members that extend into the gaps. The narrow gaps enhance uniformity of force applied to the carriage by diminishing the end effects, which enables the entire length of the air gap to be used for actuator travel.
