A suspension includes a load beam, a flexure including first and second outriggers, and first and second damper members. The first outrigger is formed to oppose the first surface and across the first opening. The second outrigger is formed to oppose the first surface and across the second opening. The first damper member is attached to the first outrigger at the first opening and the first surface. The second damper member is attached to the second outrigger at the second opening and the first surface. An edge portion of the first opening and the first damper member are spaced apart and an edge portion of the second opening and the second damper member are spaced apart.

According to one embodiment, a disk device includes a base, a discoidal recording medium including an innermost circumferential portion and an outer circumferential edge, a head, a head actuator provided pivotably on the base and supporting the head movably, a first sensor which detects a shock and a drive unit which pivots, when the shock detected by the first sensor is greater than a predetermined value and the head is located at a position less than a predetermined distance from the innermost circumferential portion, the head actuator to place the head at a position more than the predetermined distance which satisfies a conditional formula below.

An information processing apparatus includes an n-th parameter adjuster and an (n+1)-th parameter adjuster. The n-th parameter adjuster adjusts an n-th parameter set so that an n-th evaluation value set based on the n-th parameter set approaches an n-th target value set. The (n+1)-th parameter adjuster adjusts an (n+1)-th parameter set so that an (n+1)-th evaluation value set based on the (n+1)-th parameter set approaches an (n+1)-th target value set. In addition, the n-th parameter adjuster acquires, based on initial value set or search value set of the n-th parameter set, an n-th actual measured value set or an n-th predicted value set, acquires an (n+1)-th target value set based on the initial value set or the search value set of the n-th parameter set, and searches for the n-th parameter set that optimizes the (n+1)-th target value set under a restriction that the n-th evaluation value set approaches the n-th target value set using the acquired n-th actual measured value set or the n-th predicted value set and the acquired (n+1)-th target value set.

A suspension for a disk device comprises a load beam, a flexure and a damper member. The flexure overlaps the load beam, and comprises a tongue on which a slider is mounted and an outrigger connected to the tongue. The damper member is attached to the load beam. The outrigger comprises an arm opposing the load beam, and a folded portion extending from the arm and folded back in a thickness direction of the arm. Further, the folded portion is attached to the damper member.

According to one embodiment, a magnetic disk device includes a magnetic disk, a magnetic head, a sensor, a non-volatile semiconductor storage device, and a controller. The magnetic head performs writing and reading to and from the magnetic disk. The sensor detects a degree of a physical influence applied from an outside. The controller generates a log when a detection value detected by the sensor satisfies a condition for abnormality determination, and stores the log in the non-volatile semiconductor storage device in response to generation of the log.
