摘要： A device for controlling an access operation of an information recording and reproducing device to a target position for rough access in a disk-shaped recording medium prior to a precision access to a final target position, including a head carried by an actuator, a scale, a counter, a comparator, a timer, and a controller. The scale emits pulses while the head is traveling. The counter counts the pulses and then provide the count to the comparator, which calculates a difference between the count and an access distance to be traveled for rough access and then compares the difference with a value which is determined in advance in consideration of a tolerable error. The comparison result is input into the controller. If the comparison result received when the timer finishes measuring the specified time indicates that the difference between the access distance and the count falls within the range of the predetermined value, the controller decides that the actual rough access operation has been normally finished as desired, thereby decreasing a wrong judgement with respect to finish of the rough access irrespective of a value counted by the counter.

摘要： A transducer access control system for use in a disk recording/reproducing apparatus for moving a transducer a required distance from its present position over a disk in the radial direction thereof, includes a linear motor for driving the transducer, a circuit for generating a distance signal indicative of the required distance for moving the transducer, and a calculator for calculating a half distance which is a half of the required distance. To move the transducer for the required distance D, the linear motor is operated at the velocity controlled in accordance with a reference velocity signal produced from a reference velocity generator. The reference velocity is determined such that, the reference velocity is maintained at a predetermined value during the movement of the transducer in the first half of the required distance, and gradually decreases during the movement of the transducer in the second half of the required distance.
