PURPOSE:To obtain an optical head whose height is low without altering the characteristic of an actuator by assembling a mirror between a track actuator and a focus actuator. CONSTITUTION:The mirror 5 is set between the track actuator and the focus actuator. Namely, a window 17 where a laser light is made to pass is provided in the actuator case 16 and the mirror 5 is set with projecting between two track flat springs 15 and 15 through a focus bobbin 10. Thus the space adjacent to the actuator part is used as the space for setting optical parts, so that the useless space can be reduced and as for the external form of the head, the height of the whole head can be kept low because the actuator 1 is built inside a head case 2. |
