The present invention features a donor-acceptor rod-coil diblock copolymer for an organic solar cell and a method for synthesizing the same. In certain embodiments, the present invention features a donor-acceptor rod-coil diblock copolymer for an organic solar cell based on polythiophene and fullerene and a method for synthesizing the same. Preferably, the block copolymer exhibits a nanofibrillar structure in solid film and, when added to an active layer of a bulk heterojunction organic solar cell consisting of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as a compatibilizing agent, improves efficiency and stability of the solar cell.

A defect detector in a data disc system includes a defect estimation unit and a defect length counter. The defect detector inputs a RF signal from a pick-up unit for generating a defect signal. The defect length counter interprets the defect signal using a wobble signal and a header position (ESFS) signal to generate defect length information. A system controller determines which sector of the data disc has unacceptable defect from the defect length information to reassign such a sector to another available sector on the data disc.
