Abstract
Measurements of coercivity as a function of time have been performed using a nondestructive spin-stand technique. Two disks were measured using nine different test conditions, including various writing gap lengths and head to medium velocities. No spatial effects were found, but it was noticed that the results depended on subtleties of the measurement procedure
