摘要： A device for reading from and/or writing on a rotating disk including a mobile opto-electromechanical device placed above the disk and connected to a motherboard via a set of electric wires. The opto-electromechanical device includes actuators, a laser diode, photodetectors, and an electronic circuit, each photodetector providing the electronic circuit with an analog electric signal proportional to the received light signal, the electronic circuit controlling the diode and the actuators. The electronic circuit comprises an analog-to-digital converter digitizing the analog electric signals coming from the photodetectors and transmitting the digitized signals to a digital processing unit providing data of alignment of the opto-electromechanical device with respect to the disk, and a reference clock signal having its period substantially corresponding to a multiple or to a sub-multiple of the time period corresponding to the overflight by the opto-electromechanical device of a bit of the disk.
