Abstract: An optical disk drive comprising an electronic unit (PCB) comprising a first circuit (CRT1); an optical pick-up unit (OPU) movably assembled with respect to the electronic unit (PCB) circuit (CRT2) having a plurality of light sensors (PHDS) for receiving reflected light (RFL) from the (DSK), each light sensor having an output for delivering an electrical signal (Ia-Ih); and means for coupling the second circuit (CRT2) to the first circuit (CRT1) for transferring information between the first (CRT1) and second (CRT2) circuits. In a normal operational mode a number of the electrical signals (Ie,Ig;If,Ih) are combined by the second circuit (CRT2), these combined electrical signal (Ie,Ig;If,Ih) and the remaining uncombined electrical signal (Ia-Id) are transferred via the coupling means to the first circuit (CRT1). In a test model all or part of the electrical signals are separately processed by the second (CRT2).

Abstract: The invention pertains to a method for controlling radiation power of a radiation source (26), comprising the steps of a) driving the radiation source (26) in a first mode comprising the substeps of a1) determining a threshold current (Ithr) at which the radiation source (26) begins to radiate, a2) measuring the radiation power emitted by the radiation source (26), a3) driving the radiation source (26) with the threshold current (Ithr) increased with the a delta current (Idelta) for obtaining a predetermined radiation power Pr1, wherein the delta current (Idelta) is calculated by subtracting the measured radiation power (Pm) from the predetermined radiation power Pr1, b) driving the radiation source (26) in a second mode comprising the substeps of b1) determining the threshold current (Ithr), and b2) driving the radiation source (26) with the threshold current (Ithr) increased with the delta current (Idelta) for obtaining the predetermined radiation power Prt, wherein the delta current (Idelta) is calculated
