Disk drive

A disk driver unit, comprising:

• an upper head;
• an upper head support member which supports the upper head;
• a carrier which carries a disk cartridge and can rise and fall between a disk drive position and a disk attaching/detaching position;
• a slider which engages the carrier and slides between a first position and a second position so as to cause the carrier to move between the disk drive position and the disk attaching/detaching position;
• and
• a lift mechanism which has a slide piece and a link member and moves the upper head up to a recession position apart from the disk cartridge;
• wherein
• the link member is supported on and rotatable around a pivot provided on the carrier so that the link member rises and falls as the carrier rises and falls,
• one end of the link member is engaged with the slider and the other end of the link member is provided with the slide piece so that the link member rotates around the pivot as the slider moves to cause the slide piece to slip into and out of the space between the upper head and the carrier, and
• the upper head rises and falls further by means of the slide piece which slips into and out of the space between the upper head on the carrier by the link member which rotates around the pivot with the movement of the slider, in addition to the rise and fall movement of the carrier.
