Abstract
Disclosed herein is a laser driving method including the step of adjusting an initial value of driving current for driving a laser when an operation mode is changed on a basis of a difference in magnitude between a first bias current including information on threshold current of the laser in a first operation mode and a second bias current including information on the threshold current in a second operation mode.
