Abstract
Future Consumer Electronic (CE) applications will make widespread use of existing desktop Hard Disk Drive (HDD) technology for audiovisual (A/V) recording and playback purposes. In mobile applications storage drives may encounter more shock & vibrations compared to office or in home applications. Philips as a system integrator has applied a new tool to test the sensitivity of storage devices under such conditions. In this tool the Streaming Performance of the drive is monitored. It is concluded that some hard disk drives will have difficulties in meeting AV streaming criteria at vibration levels below those provided in the Shock & Vibration specifications. This tool is also useful to analyze specific frequencies for which the drive is particularly sensitive and for which special excitation prevention measures should be considered in the end product design.
