A second pole piece layer of a write head is constructed using first and second photoresist layers which are sensitive to light with different bandwidths. A process detector includes a replica of the input buffer. The bottom section functions as a mounting shelf for the top section and is structured not only in the same flexible semi-circular fashion, but is designed in such a way as to capture the flower box section allowing it to rest securely on the mounting shelf or bottom section. The matrix resin may further contain at least one of a p-aminophenol-type epoxy resin having three epoxy groups in one molecule, and a tetramethylbiphenol-type solid epoxy resin having two epoxy groups in one molecule. The frame includes a deck support and a deck supporting the mattress. The CIGS type solar cell includes a CIGS light absorbing layer, a buffer layer and a transparent electrode layer provided in this order on a substrate.
