Abstract:
A reproduction apparatus (1)which is arranged for reproducing data (A, D, ID) stored along at least one track on a rotary drivable optically readable data carrier (2) and which includes drive means (6), which are arranged for receiving a drive signal (AS) and for driving the data carrier (2) in accordance with the received drive signal (AS), and which includes reading means (13) which are arranged for reading the stored data (A, D, ID) and for delivering the read data (AD) and which includes drive control means (24) which are arranged for receiving and evaluating the read data (AD) and for generating and delivering a controlled drive signal (S1) while the read data (AD) are used, to enable the data carrier (2) to be driven in accordance with the controlled drive signal (S1), and which includes detection means (45) with whose help there may be detected whether read data suitable for generating the controlled drive signal (S1) are available and which are arranged for delivering a detection signal (DS) when such suitable data (AD) are lacking, characterized in that additional drive control means (42) are provided which are arranged for generating and delivering a controlled drive signal (S2) and in that control means (40) are provided which are arranged for receiving the detection signal (DS) and which, as a result of receiving the detection signal (DS), enable to drive the data carrier (2) in accordance with the controlled drive signal (S2).
