Abstract
In the carriage assembly of a disk drive, thermally compensating elements are positioned between the support structure for the carriage and a fixed guide plate which is associated with an outrigger bearing of the carriage. Compensation is achieved for expansion of the carriage base and displacement of the fixed guide plate and the outrigger bearing which results from thermal change, thereby precluding roll of the carriage.
