Disk device having powder removal apparatus and disk device having timing offsetting apparatus for loading

A disk device comprising:

• a chassis base;
• at least one disk rotatably supported on said chassis base;
• at least two carriage arms pivotable about an axis on one end and, at the other end, having a slider with a read/write head and a load bar extending from said slider;
• a ramp member attached to said chassis base at a position outside said disk, said ramp member having a guiding part and a parking part;
• an actuator for driving said carriage arms between a loaded position in which said slider is held above said disk and an unloaded position in which said load bar rests on said parking part of said ramp member, and
• timing offsetting means for offsetting the timing of said load bar of one of said carriage arms ascending said guiding part from the timing of said load bar of one of the other carriage arms ascending said guiding part when said carriage arms are driven to move from the unloaded position to the loaded position,
• wherein said guiding part comprises a disk-side ramp surface closer to the disk, a parking part-side ramp surface adjacent the parking part and an intermediate surface, and
• said timing offsetting means is configured such that said parking part-side ramp surfaces are provided in a mutually offset manner in a direction of movement of the load bar when the said carriage arms are driven to move from the unloaded position to the loaded position.

• an actuator for driving said carriage arms between a loaded position in which said slider is held above said disk and an unloaded position in which said load bar rests on said parking part of said ramp member,
• wherein said ramp member is provided with cleaning means for removing powder attached to said load bar as said load bar moves along the parking part, and
• timing offsetting means is provided for offsetting the timing of said load bar of one of said carriage arms ascending said guiding part from the timing of said load bar of one of the other carriage arms ascending said guiding part when said carriage arms are driven to move from the unloaded position to the loaded position,
• wherein said guiding part comprises a disk-side ramp surface closer to the disk, a parking-part side ramp surface adjacent the parking part and an intermediate surface, and
