The present invention relates to a switch driving circuit and a driving method thereof that are capable of preventing hard switching. Respective elements d required to define a transitional motion action are calculated from the respective frames after the end point of the former motion and before the start point of the latter motion. The optical disk has data blocks for recording data, and spare blocks for replacing defect data blocks. Because the other non-selected bitlines are held at the program inhibit voltage level, they will not be inadvertently programmed when the programming voltage is supplied by the word line. Consequently, the selling of the picture can be made so as to satisfy the intention of the seller.
