An optical disk drive for wireless power transmission, comprising:
- a tray on which an optical disk is to be seated;
- a driving unit for rotating the optical disk to be seated on the tray and reading or writing the optical disk;
- a wireless power transmitting module to be seated on the tray and comprising a primary coil and a transmitting circuit unit;
- a power supply unit for supplying power;
- and a controller for controlling the power supply unit to supply power to the wireless power transmitting module when determining that the wireless power transmitting module is seated on the tray,
- wherein the controller controls the driving unit to drive a spindle motor to rotate an object seated on the tray, and determines whether the wireless power transmitting module is seated on the tray based on a signal reflected from the object and a second signal generated from the spindle motor.
An optical disk drive for wireless power transmission, comprising:
- a tray on which an optical disk is to be seated;
- a driving unit for rotating the optical disk to be seated on the tray and reading or writing the optical disk;
- a wireless power transmitting module to be seated on the tray and comprising a primary coil and a transmitting circuit unit;
- a power supply unit for supplying power;
