A reproduction apparatus (1) for reproducing data (A, D, ID) stored on a rotary drivable optically readable data carrier (2) includes drive means (6) for driving the data carrier (2) in accordance with a drive signal (AS), and drive control means (24) for generating a controlled drive signal (S1) while the read data (AD) are used, and detection means (45) for detecting whether data (AD) suitable for generating the controlled drive signal (S1) are available, and additional drive control means (42) for generating a controlled drive signal (S2), and control means (40) which are arranged for enabling the data carrier (2) to be driven in accordance with the controlled drive signal (S2) when data (AD) suitable for driving the data carrier (2) are lacking.
