<p>An apparatus for generating clock signals for reproducing data and an apparatus for reproducing data are disclosed. With the apparatus for generating clock signals, reference clock signals actually recorded on a recording medium are sampled (10, 16) by using (11, 12) a number of outside clock signals having respectively different phases to find the maximum value of the differences of the sampling values sampled by the outside clock signals, and the outside clock signal associated with the maximum value is used as data-reproducing clock signal. With the apparatus for reproducing data, the outside clock signal associated with the maximum value is used as the data-reproducing clock signal, while the reproduced data signals are sampled with the outside clock signals, and the difference of these sampling values is compared to about one-half the maximum value of the sampling values of reproduced signals of said reference clock signals to perform data reproduction with a high noise margin. <IMAGE></p> |
