Abstract: The check valve unit of a hydraulic tensioner comprises a check ball, a ball guide and a disc-shaped retainer. The retainer is fixed to the high pressure oil chamber side of the ball guide by crimping an annular portion of the ball guide over the outer edge of the retainer so that substantially all of an annular circumferential portion of the high pressure chamber side of the retainer is held underneath the crimped portion of the ball guide. The crimped portion of the ball guide forms a recess for receiving and positioning a plunger-biasing spring. A ball seat is similarly secured to the inflow side of the ball guide by crimping.

Abstract: A disk drive correctly recognizes newly written data when a plurality of readable data exist on the same sector of the same track, by comparing AGC values of each of the readable data, comparing error rates generated by Viterbi decoding, or both. An offset value determining means determines whether an offset value when the data is read has exceeded a predetermined value when the data is read. An offset control means controls the head, on the basis of the determination result of the offset value determining means, to conduct the offset operation on the opposite side of the track when the data is read the first time, and a selecting means selects the new data recorded in the sector by comparing the results obtained for both sets of data.
