A material which comprises a polyrotaxane and a polymer and is crosslinked by irradiation with light. The read sensor comprises first and second Co\u2014Fe buffer layers in the lower and upper portions of a keeper layer structure, respectively, third and fourth Co\u2014Fe buffer layers in the lower and upper portion of a reference layer structure, respectively, and a fifth Co\u2014Fe buffer layer in the lower portion of a sense layer structure. The second solar panel carrier is placed on the support structure and advanced into contact with the first solar panel carrier and both can be advanced together along the support structure. The inorganic protective film covers the end of the resin protective film and further extends to the dividing region. The method further comprises detecting at least one characteristic feature of the test field in the images of the image sequence.
