Abstract: PROBLEM TO BE SOLVED: To eliminate necessity for retracting a finger after loading the head by providing a base plate and a finger which is coupled to rotate to the base plate being coupled with a flexure arm at the position where it is never in contact with the upper edge of a rail. SOLUTION: A rotor 24 is provided with a finger 30 which is coupled to rotate with a base plate 26. The finger 30 is also coupled with a flexure arm 28 to surely prevent the head 14 to be in contact with a disc when a linear actuator moves the head 14 in the direction to cross the disc. The flexure arm 28 has a pair of bent rails 32 to increase rigidity. The finger 30 has the shape which disable the contact thereof with the upper edge of the bent rail 32 when the finger 30 is coupled with the flexure arm 28. The finger 30 has the thickness to make smaller the gap between the disc and the part of flexure arm 28 other than the rail when the head 14 is engaged with the disc.
