PURPOSE: An optical pick-up including a tracking coil having an inclined angle is provided to maintain the turn number or size of the tracking coil of a standard value and secure an optical path formed between a hologram module and a full-reflection mirror, thereby preventing the efficiency of light emitted from the hologram module from being deteriorated. CONSTITUTION: An optical pick-up including a tracking coil having an inclined angle includes an objective lens for focusing light emitted from an optical source on a recording face of an optical disk, an actuator for variably moving the objective lens, and a tracking coil(401,402) for driving the actuator. The tracking coil has a predetermined inclined angle with respect to longer axis direction and is fixed to the side of the actuator.
