<p>An apparatus for reading data stored on a data storage medium (12). The apparatus includes an optical pickup (14) for reproducing data stored on the data storage medium (12), an error detector (30) coupled to the data readout pickup (14) for detecting an error rate at which errors occur in the data reprodused by the data readout pickup (14), a readout controller (16/16a, 18, 28, 10) for operating the data readout pickup (14) at a selected data readout rate and a system controller (32) coupled to the error detector (30) and the readout controler (16/16a, 18, 28, 10) for comparing the error rate to a predetermined system maximum error rate and for establishing the selected data readout rate such that the error rate is below the predetermined system maximum error rate.</p> |
