Abstract: A method for producing a complementary model includes acquiring distribution information and incomplete distribution information as a dataset for learning and training the complementary model using the dataset. The distribution information indicates a distribution of an amount of a transport object in a drop target of a work machine, and the incomplete distribution information is information from which some values of the distribution information are missing. The complementary model is trained using the dataset such that when the incomplete distribution information is used as an input value, the complementary model complements the missing values and outputs the distribution information an output value.

Abstract: In a disk device in which heads are positioned by a servo mechanism, the object of the present invention is to prevent data from being destroyed by incorrect selection of a head and to improve reliability in recording or reproducing information and to prevent format efficiency from being decreased thereby. For this object, a SAM pattern in a servo information region is changed for each head and recorded. Then, the SAM pattern is read to determine which head makes access to a disk surface and the head is compared with a head to which a direction of making access is given thereby to make an error check. Moreover, by the use of a marker pattern of rotational synchronization compensating data added to the servo information, an error check of the head making access to the disc surface is conducted.

Abstract: Settling response characteristics after change-over from a speed controller to a position controller is attained. Fluctuations in a time taken until change-over is made from the speed controller to the position controller are reduced to stabilize a moving time and to shorten an access time. To this end, a position controller generates a drive signal of a linear or primary function of time in such a manner that a position deviation signal responds to it with a ternary-order function of time which becomes zero in a desired finite settling time. Further, a feedforward signal generator is provided to reduce a follow-up error to a target position signal as an output of a target position signal generator.
