摘要
A method of corrosion susceptibility testing of a magnetic recording head is disclosed. The method includes applying simulated disk corrosion products containing cobalt salts to the recording head. The recording head is then placed in an environmental chamber with elevated temperature and humidity. The resistance of the sensor on the recording head is measured after removal from the chamber and compared with the resistance before placement in the chamber. A significant change in resistance indicates a corrosion failure. This component level testing gives a more accurate indication of the corrosion performance of the recording head when placed in a disk drive.
