| Zusammenfassung: | A control module for an automatic gain control device of an optical disc playback apparatus includes a constant-gain setting member and a switch member. The playback apparatus includes an optical pickup head for reading an optical disc. The constant-gain setting member provides a constant gain signal. The switch member connects the constant-gain setting member to the automatic gain control device so as to set the automatic gain control device at a predetermined gain when the optical pickup head reads a non-recorded area of the optical disc or performs a track jump operation. |
