Abstract
A data storage device for use with a rotatable data storage medium having a data head and a controller for controlling movement of said data head characterized in that said controller varies the time taken for moving said data head between given positions in response to the state of said device. Particular embodiments of the invention coordinate the movement of the data head with the rotational position of the data storage medium so that the data head arrives at the desired position at the same time as the portion of the data storage medium to be accessed arrives beneath the data head. In other embodiments the time taken to move the data head between given positions is increased if the temperature of the mechanism for moving the data head exceeds a predetermined value.
