Abstract:
A method for self-servowriting a disk drive comprising the steps of:transferring a magnetic pattern by magnetic printing onto at least one storage surface of a disk, wherein a resulting printed magnetic pattern includes servo information and wherein the printed magnetic pattern has a resolution lower than a disk drive servo pattern specification based on head gaps of data transducers included in the disk drive,assembling the disk drive including installing the disk into the disk drive and enclosing the disk and the data transducers within a housing sealed against particulate contamination from an external ambient environment,reading the printed magnetic pattern in order to aid precise positioning of the data transducers relative to storage locations defined by disk storage surfaces,self-writing disk drive servo patterns onto the storage surfaces at the concentric track locations with the data transducers in accordance with the disk drive servo pattern specification after the disk and data transducers have been enclosed within the housing.
