AGING MODE

•Mode which repeatedly changes and plays back discs automati- cally in the unit.

•It will repeat aging as long as no errors occur.

•If an error occurs during aging, it will stop all servos, motors, etc. instantaneously, display the error number, and stop opera- tions. However, the stopping conditions differ according to whether the unit is equipped with the “self-protection function during errors” described later.

The function serves to maintain the state of the unit when errors occur.

• Aging cycle count function *3

*1 Disc setting mode:

5 discs are set before setting the aging mode. This mode makes the setting of these discs more easy.

*2 Switching of use/disuse of protection function in errors: Function which voluntarily corrects errors which occur dur- ing normal operations by retries.

If this function is not provided, all operations will be stopped without retiring. It is suitable for checking errors with low re- producibility.

If this function is provided, and errors can be corrected by retries, aging will be continued without stopping.

(The normal aging should be performed with “be”.)
