    摘要： The present disclosure relates to a polymer electrolyte membrane having a construction wherein an ionomer is charged in pores of a nanoweb having a high melting point, being insoluble in an organic solvent and having excellent pore characteristics, under optimum conditions. Therefore, an overall thickness of the electrolyte membrane may be reduced, thereby attaining advantages such as decrease in ohmic loss, reduction of material costs, excellent heat resistance, low thickness expansion rate which in turn prevents proton conductivity from being deteriorated over a long term. The polymer electrolyte membrane of the present invention comprises a porous nanoweb having a melting point of 300□ or more and being insoluble in an organic solvent of NMP, DMF, DMA, or DMSO at room temperature; and an ionomer which is charged in pores of the porous nanoweb and contains a hydrocarbon material soluble in the organic solvent at room temperature.

    摘要： A hard disk drive with a disk that contains a target track and an adjacent track. The drive includes a circuit that determines an error in data read from the target track. Data from the adjacent track is stored in memory. The adjacent track is then erased and the target track data is re-read from the target track. Erasing the adjacent track allows the target track data to be read without adjacent track interference. The data from the adjacent track is typically rewritten onto the disk from memory so no data is lost.
