Abstract
An object of the invention is to provide an optical pickup apparatus that succeeded in achieving easy wiring layout and slenderization, and an easy adjustment method therefor. In the optical pickup apparatus, the position of the working light with respect to the recording medium is adjusted by positionally adjusting at least one of the optical components. Particularly by forming the opening portion in an area of the first wiring board which is located in proximity to the optical component, the wiring region of the first wiring board can be secured without covering the optical component completely.
Claims15
An optical pickup apparatus comprising:
- a plurality of optical components including a light-emitting element which emits working light for recording or reproducing information with respect to a recording medium;
- a housing for mounting therein the optical components;
- and
- a first wiring board which is electrically connected to the light-emitting element,
- wherein at least one of the optical components is made positionally adjustable,
- and wherein the first wiring board has an opening portion formed in an area thereof which is located in proximity to the positionally-adjustable optical component.
A method for adjusting an optical pickup apparatus composed of a plurality of optical components including a light-emitting element which emits working light for recording or reproducing information with respect to a recording medium;
- a housing for mounting therein the optical components;
- and a first wiring board which is electrically connected to the light-emitting element, comprising the steps of:
- making at least one of the optical components positionally adjustable;
- forming an opening portion in an area of the first wiring board which faces toward part of the optical component that undergoes significant displacement at the time of positional adjustment;
- and
- adjusting the position of the positionally-adjustable optical component by means of an adjustment tool inserted externally through the opening portion.
