Output (English): In the present invention there is disclosed a device for reading an information carrier (1) on which an information pattern is recorded in the form of substantially parallel running tracks of readable effects (21, 22), the device comprising: a read head (3) for generating a read signal (10) by scanning the information carrier (1) at a scanning position (13), servo tracking means (7) for keeping the scanning position (13) on the track, and discriminating means (9) for determining a type of the information carrier (1), whereby the information pattern has at least one different physical parameter for each type of the information carrier(1). The discriminating means (9) are adapted for positioning the read head (3) into a predetermined distance from a predetermined reference position on the information carrier (1), while the servo tracking means (7) are out of operation and for determining the type of the information carrier (1) on the basis of read-signal properties related to the physica
