SHOCK-RESPONSE-SPECTRUM ANALYSIS FOR ACOUSTIC NOISE OF A SEEKING CONTROL SYSTEM IN A HARD DISK DRIVE
スポンサーリンク
概要
- 論文の詳細を見る
Shock-response-spectrum (SRS) analysis of a seeking current in a hard disk drive was used to predict acoustic noise frequencies. This analysis method can be used for optimizing the seeking current so that seeking noise is reduced. It was verified experimentally that the prediction accuracy is from -25% to +12% and seeking noise was reduced by about 4 dBA on average by optimizing the seeking current.
