Does leaving a DVD show in pause for hours at a time damage the disk?

Does anyone know whether any damage occurs if someone is playing show from a DVD and then presses Pause, and then leaves it that way for many hours, so later in the day he can resume watching the show from where he left off?
I'm asking because one of my DVDs got scratched, and it has a show that I play often. Perhaps I mishandled the DVD, but since I'm usually very careful about that, I was wondering if it may be because of all the times I left the disc on Pause.
Thank you

Hi there,

no, normally it would not take any extra damage.
But...

The disc will age faster since you expoce it to warmth for an extended time.
But why don't you just power down the player and start it up again when you
want to go on watching your show? Most players I know simply start to play right
where you stopped 'em before.

As far as i know most DVD drives will power down after a certain period of inactivity ( and this includes pause). Generally a scratch on a disk like that is caused by a fragment or particulate on the disk, caddy, or tray while the disk is playing. It happens during the speed up - and then it will generally fly off.

I dont think pause will cause any more damage other than the heat... but this shouldnt significantly shorten the life.

Thanks for your input.
Doc, I am not watching a movie. I am watching replays of old television shows, and no, they do not start where they left off the next time I play the DVD.

Wool, the driver does not power down even hours later.

So I take it from you guys that I should not be doing what I'm doing, because of the heat problem.

In that case if you ensure the disk is clean when you put it in, in addition to the tray etc you should be fine. While the disk is rotating it will get hotter than when its not, due to the rotation/stress and warmth of the drive - this wont increase the likelihood of scratches tho.

I work at a museum currently and we have the same DVD in a unit 12 hours a day playing constantly, its been like that for say... 6 years and its still working so that should be indicative of a extreme usecase :)

Wool- very helpful info. Yet I would feel better if you had said that your DVD was often left in Pause for hrs at a time. It could be the Pause - by holding a specific spot - damages a DVD when left there for hrs

But the disk doesnt stop spinning or constantly read from the same spot when paused... if your unit doesnt power down the disk is spinning still so its not damaging the same section. If anything my use case places more strain on the disk as its constantly reading.. yours simply reads the section into memory, decodes, ooutputs to the TV and holds the read operation wile keeping the disk moving...

Its not like you are stuck on the same place of the disk...

So essentially (above article) while the disk is still spinning (to avoid spin-up when unpausing) there is 1) no contact with the disk so no friction and 2) its not reading the same frame from the disk constantly, it uses framebuffer and mearly maintains the spin of the disk.

SHort answer, nothing to worry about, certainly no more prone to scratches.
