Stress? for stopping starting and finding the spot again vs. leting it run in pause for any long time? Who knows for real. Someone might 'decide' they know, but I do not think any studies have been done on 'mean time to failure' comparing those issues.
When the unit is in pause, the tracking is in full use, thenlaser is reading, in order to hold the spot on the CD.
I just can't say anything about it.
Like when a flourecent light is left on it is better than turning it off if it is going to be used again within so much time. Same for a computer, better to leave on than turn off and back on within a hour.
But for a disc to stop or stay in pause.????
I mean yes leave it in pause if you have to answer the phone, or run to the restroom, Even to go eat dinner. .. but to leave it in pause overnight? ahhh no. Just my opinion.
