Abstract:
A hard disk drive bypass channel architecture incorporates enhanced cooling for voice coil motors. A cooling slot formed in a bypass channel component that is adjacent to the VCM alleviates VCM overheating problems. The slot compromises airflow from the bypass channel to provide sufficient secondary flow to cool the VCM and actuator coil area. The slot may be formed in the integrated wall of the spoiler or diverter. The spoiler has an extension in which the cooling slot is formed.
