By the ticking / clicking I meant the problem where laser can't read the data from the disc, when it happens the laser itself doesn't move, just lens keep on raising and falling while trying to read the data, which cause certain clicking noise.

You're correct, the sound you mentioned above "laser moving back and forth" is normal and if you hear only this, you shouldn't be worried, it means that your laser is in good condition.
I'm glad I could help.
