Abstract
In a disk drive system, a data transducer control during a seek operation is based on the distance to be traversed. Acceleration of a motor coupled to the head initiates movement of the head. Deceleration of the motor is initiated based on the distance traversed by the head.
Claims20
A method for accessing information on a rotating storage medium comprising:
- receiving a request to perform a seek operation, the request including information indicative of a destination location on the storage medium;
- accelerating a data transducer to move it from a starting location on the storage medium to the destination location;
- and
- initiating deceleration mode of the data transducer at a time that varies depending on the distance between the starting location and the destination location.
1 more element
A disk drive system comprising:
- a rotating storage medium;
- a data transducer disposed relative to the storage medium to effect data transfer with the storage medium;
- a motor operatively coupled to the data transducer to effect motion of the data transducer relative to the storage medium from a first location to a second location;
- a controller component operably coupled to control the motor and configured to accelerate the motor and to initiate a deceleration mode of the motor based on the distance between the first location and the second location.
1 more element
A disk drive system comprising:
- a rotatable storage medium;
- head means for exchanging data with the storage medium, the head means configured to be movable atop a surface of the storage medium;
- and
- controller means for moving the head means from a starting location to a destination location, the controller means effective to accelerate the head means, the controller means further effective, subsequent to accelerating the head means, to initiate a deceleration mode of the head means when the head means has traversed a distance that is based on the distance between the starting location and the destination location.
