【発明の名称】磁気ディスク装置の耐衝撃構造
Document Type and Number:
Japanese Patent JP2667372
Kind Code:
B2
Abstract:
When an HDD is subjected to shock with a magnetic head (22) retracted to the parking zone, a suspension (34) having a magnetic head (36) at the free end thereof swings. When a lowest suspension (34) swings, the free end of the suspension (34) is brought into contact with a pin projection (50) and further displacement toward the base (12) is impeded. The suspension (34) that further swings in this condition presents not a swing in a primary mode (cantilever support mode) but a swing in a secondary mode (two-point support mode), and the maximum displacement of the suspension (34) occurs at the longitudinal intermediate portion of the suspension (34). The intermediate portion that is displaced is made to go into a groove (48), and the contact of the intermediate portion of the suspension (34) with the base (12) is impeded by the groove (48).
