Abstract: Disclosed is an improved microform card which includes a wearstrip spacer element structure located on the card surface in one of several configurations, some containing coded secondary information. The wear-strip spacer elements separate the card surface from adjacent optical elements in a card utilizing apparatus by a distance sufficient to prevent the formation of colored Newton rings at the card-to-optical-element interface. Card utilization equipment capable of recognizing the presence of wear-strip spacer elements on a microform card and using any secondary information encoded thereon is also disclosed.
