Recorded data reading system
First Claim
1. An apparatus for reading data stored on a data storage medium, comprising:
- data readout means for reproducing data stored on the data storage medium;
error detection means, coupled to the data readout means, for detecting an error rate at which errors occur in the data reproduced by the data readout means;
readout control means for operating the data readout means at a selected data readout rate; and
system control means, coupled to the error detection means and the readout control means, for comparing the error rate to a predetermined system maximum error rate and for increasing the selected data readout rate when the error rate is below the predetermined system maximum error rate.

Abstract
An apparatus for reading data stored on a data storage medium. The apparatus includes a data readout device for reproducing data stored on the data storage medium, an error detecter coupled to the data readout device for detecting an error rate at which errors occur in the data reproduced by the data readout device, a readout controller for operating the data readout device at a selected data readout rate and a system controller coupled to the error detecter and the readout controller 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.

13. A method for reproducing data stored on a data storage medium, comprising the steps of:
-
reading data from the data storage medium at a selected data readout rate; determining an error rate of data read from the data storage medium; comparing the error rate to a predetermined system maximum error rate; increasing the selected data readout rate when the error rate is below the predetermined system maximum error rate.

14. A method for reproducing data stored on a data storage medium, comprising the steps of:
-
reading data from the data storage medium at a selected data readout rate; determining an error rate of data read from the data storage medium; comparing the error rate to a predetermined system maximum error rate; decreasing the selected data readout rate when the error rate is above the system maximum error rate.
