Parking does not stress the disc's surface but rather the head movement mechanics. Remember, parking must be fast enough to protect against imminent damage. (Consider for example HP's HDAPS technology.) Thus excessive load/unload cycles *are* stressful and *will* damage the drive. Why else would the manufacturers specify minimum values in their data sheets?
