A flexible support mechanism for a hard-disk drive (HDD) was devised, prototyped, and evaluated. It was shown that when a HDD is supported flexibly by, the vibration disturbance to the HDD caused by becomes lower frequency. Moreover, the resonance frequency of the HDD with a flexible support mechanism is lower than the HDD itself. The flexible support mechanism has a high interception rate to in regards to the disturbance inputted into the HDD. It is therefore possible to reduce the positioning error of the HDD by applying such a flexible support structure. The data-transfer rate of the HDD decreases when the head-positioning error becomes large, because a longer read/write time is required. Since the head-positioning error can be reduced by applying the flexible support mechanism, degradation of the read/write performance by vibration disturbance can be prevented. In addition, a HDD with the prototyped flexible support mechanism showed 2.0-time-higher power-proof than HDD itself.
