Data reproducing apparatus. |
摘要 |
<p>Data reproducing apparatus (10) demodulates digital data recorded on a magnetic recording medium (3) using a clock regeneration circuit (11) having a phase locked loop circuit arrangement (12 to 14, 16). A lock frequency of the clock regeneration circuit (11) is switch-controlled by a control circuit (15). Even if modulation systems having different recording densities are used, the bit error rate during demodulation can be decreased.</p> |
