摘要:
A driving device for performing a recording and/or reproducing operation for a recording medium, such as a flexible disc, and a fixed speed movement servo method carried out on such driving device. A head for recording and/or reproducing the information for a recording medium is run at a fixed speed using initial servo parameters as certain fixed values to calculate optimum servo parameters. Using the calculated servo parameters, constant speed servo is executed to realize the head running at a fixed speed. This achieves constant speed movement at a certain speed within a pre-set speed range regardless of individual characteristics or occasional posture of the recording/reproducing apparatus.
摘要:
A servo control apparatus comprises an abnormality detection circuit which calculates a difference between the quantity of rotation of a servo motor from a reference point calculated on the basis of an accumulated value of the position feedback and the quantity of rotation of the servo motor from the reference point counted by a rotational detector, and puts out an absolute position abnormality signal when the calculated difference value exceeds a predetermined value.

摘要:
In a recording/reproducing apparatus, a controller includes a counter responsive to incoming track feed requesting pulses to count the number of the pulses, a head movable state detection unit for detecting a movable state of a magnetic head, and a track feed controller responsive to the count value of the track feed requesting pulse counter to effect track feed of the magnetic head. Detection of the movable state depends on the recording medium being loaded and on completion of the formulation of track position information that is derived from an optical signal that varies as a function of track position. The track feed controller effects track feed of the magnetic head, responsive to the count value of the track feed requesting pulse counter, following detection of the movable state of the magnetic head.
摘要:
A reproducing apparatus includes access means for accessing a recording medium so that an information signal is read out from the recording medium, detecting means for counting frequency with which the access means accesses the same recording unit region of the recording medium and detecting a recording unit region of high access frequency, random number generating means for generating a random number, and moving means for moving the access means to other recording unit region on the recording medium in response to a random number generated from the random number generating means after the access means accesses the recording unit region of high access frequency detected by the detecting means.
