Disk device, and disk changing method for disk device

A disk changing method for a disk device comprising a stock unit in which multiple disk holders are arrayed in the direction of the thickness of a disk;

• a selecting unit for transferring said disk holders in said direction and transferring one of the disk holders to a selecting position;
• a rotational driving unit for clamping a disk;
• and a transporting unit for nipping the outer edge of a disk by a pair of nipping members so as to transport the disk between a disk holder at said selecting position and said rotational driving unit, said method comprising:
• prior to performing a selecting operation by said selection unit, the spacing between said nipping members is set so that said nipping members are separated from the outer edge of the disk and said rotational driving unit is moved to a retracted position so as not to overlap with the disk held by said disk holder, and after one of said disk holders moves to said selecting position and stops, first said nipping members nip a disk by decreasing the spacing between said pair of nipping members, and following completion of this nipping, said rotational driving unit is moved to the driving position at which said rotational driving unit overlaps with the disk held by the disk holder and the disk held by the disk holder at the selecting position is transported by said nipping members to a position at which said rotational driving unit can clamp the disk.

• and
• when one of said disk holders moves to said selecting position, after said nipping members nip the disk by decreasing the spacing between said pair of nipping members, the spacing between said nipping members is further decreased;
• subsequently, said spacing is increased so that said nipping members can provide a transporting force to said disk, after which said rotational driving unit is moved to the driving position at which said rotational driving unit overlaps with the disk held by the disk holder;
• and the disk held by the disk holder at the selecting position is transferred by the transporting force of said nipping members to the position at which said rotational driving unit can clamp the disk.
