Abstract
A tape medium has an identification segment located on a transparent leader segment of the tape medium for optical detection of the segment identification pattern. The segment identification pattern and the medium identification pattern have a predefined spatial relationship, enabling photo-optical detection of the segment identification pattern and reading of the medium identification pattern. The medium identification pattern carries various medium identification information, such as tape manufacturer, tape serial number and a tape medium property.
