When reading data from an HDD, the actuator arm moves the ____ to the precise location on a spinning ____, which is divided into ____ and sectors. The read head detects tiny magnetic changes on the disk surface, which correspond to ____ values. These magnetic signals are converted by the drive's electronics into digital data that the computer can process. This precise positioning and detection allow for accurate and efficient data retrieval from large storage volumes.
