Abstract: PROBLEM TO BE SOLVED: To prevent the signal recording surface of a disk from being damaged when a large diameter optical disk or a small diameter optical disk is inserted into a disk inserting/ejecting port. SOLUTION: A disk drive device is provided with an insertion guide member 110 which guides large and small diameter optical disks 2A and 2B that are to be inserted into a disk inserting/ejecting port 19 while the insertion angles of the disks are being controlled. When a base 27 is located at a chucking release position, the insertion guide member 110 is raised to the position where the insertion angle of an optical disk 2 that is inserted from the port 19 is controlled. When the base 27 is located at a chucking position, the insertion guide member 110 is lowered to the position where the optical disk 2 mounted on a turntable 23 is separated.

Abstract: PROBLEM TO BE SOLVED: To provide a hard disk device having a protection control means for avoiding a vital damage when an impact is applied to the device, and information processor which contains this hard disk device. SOLUTION: This device rotates a magnetic disk 3 and moves a slider constituted with a magnetic head in the radial direction of this magnetic disk 3 to perform recording/reproducing. In such a case, the device includes an acceleration detecting means (acceleration sensors 7z, 7x, 7y) for detecting the external force exerted on the hard disk device and has the protection control means which saves the slider from the recording/reproducing region of the magnetic disk 3 when the absolute value α(m/s ) of the square root calculated by (αz +αx +αy ) of the accelerations (αz , αx , αy ) detected by the acceleration detecting means is α =1.4(m/s) where the time when the acceleration is below the gravity acceleration G(m/s2 ) is defined as t (s).
