ABSTRACT:
In a data reproducing device using a read channel of a PRML system, during a period of a continuous reproducing operation mode for continuous reproduction processing of adjacent data sectors, a restart RG generator switches a restart read gate signal RRG ON in synchronization with switching ON of a reference read gate signal RG. Therefore, when data is reproduced from a data sector before continuous data sectors, data reproduction processing is started by means of the restart read gate signal RRG equivalent to the reference read gate signal RG. When data is continuously reproduced from a next data sector adjacent to the previous data sector, the restart RG generator switches the restart read gate signal RRG ON ahead of the reference read gate signal RG by a specified period.
