Store DVD disc inside the ziplock with silica gel sachet no need to remove the disc inside the black case? inside the black case has moisture? the loose disk inside the ziplock along with silica gel sachet?

To recap: Disc, either CD, DVD, or Blu-ray. Inside either a sleeve or a (non-airtight) plastic case. Packet of silica gel outside the case but inside the Ziploc bag. Ziploc bag around everything, closed airtight. Will keep moisture in the contents to the bare minimum. |
Thank you very much the answer thank you clarified my doubt if the case would maintain humidity inside and the silica would not absorb
If I keep DVD MDisc inside ziplock bag with silica gel the durability of the disc would greatly increase? unfortunately I can not lower the temperature of my room is variation 31-35 Cº |

It sounds as if you're very concerned about these discs. I'd say to get a box of M-Discs and a box of the premium Verbatim discs which Lordsmurf recommends. Burn four copies of each disc you want to preserve...two M-Discs and two Verbatims...verify the discs after burning to ensure data integrity, then pack them in Ziploc bags with silica gel and store them separately. Put one copy at your uncle's or parents' house in case your house floods or burns down. Odds are at least one disc survives longer than you do. But I can't give you a money-back guarantee. |
I already have 4 copies verbatim and mdisc but I keep in black case box inside closed cardboard boxes and this box on top of wardrobe of a ventilated natural ventilated room, currently I do not use silica gel and ziplock
My MDisc Verbatim and DVD-R Verbatim AZO DVD's have an expectation of 15 years from the burning date of 2017 and in my storage conditions 50-67% on days without rain and on rainy days high humidity and temperature varies 30- 35ºC, with the use of ziplock bag and silica gel sachet that can expand to how many more years? temperature will always be the same 1) If the bag is hermetic without silica gel, is it bad for disc conservation because the moisture is always present in the bag? 2) I put all the disks inside a ziplock bag closed with silica gel, if for some reason there is any hole or opening in the zip bag the conservation and internal moisture will be equal to store without the zip bag and without silica? |

1) I can not know how much moisture is inside the bag but is it worse the bag being hermetic with moisture inside it detracts from the longevity of optical media? in my case I put silica gel sachets but I do not know if the zip bag is totally hermetic and has hole 2) If the zip bag is not airtight and contains holes or openings will the outside air enter the bag and remove accumulated moisture or is it necessary to remove the bag for greater air exchange and lower exposure to moisture ?? 3) the zip bags I tested all of them I put fan air and closed the zips and after 24 hours I saw that they a little dried |
Look, GM. I've done just about all I can from five thousand miles away. I can't give authoritative answers without seeing your setup...and, even if I did, there are many more qualified authorities. Perhaps you should hire a local consultant. Or at least use double bags with silica gel packets inside each bag; in this case BOTH bags need to have holes for the moisture to enter. Dry the silica gel packets out once a year, in a warm oven; use new bags each year, and check the bags for leaks before you put the DVDs and silica gel inside it. Or maybe you need to install and use air conditioning.
Take reasonable precautions, but some things are just out of our hands. I get that these discs are important to you, but the people around you are even more important. Take care of them first, and don't obsess over things that you can't control. |

in the other case if the zip bag with silica gel inside has some hole or opening the moisture enters but if the outside air is dry does it enter the zip and expel moisture? Does not she stay in the bag? |
The gift that keeps on giving, always good for a laugh.

I just use those sealeable freezer bags for both my tape and disc mediums and renew them when they are taken out for viewing.
Personally I wouldn't obsess over it. Just take the precautions you are and live. You would be better off making copies on known good brand media and on different storage mediums if you are that paranoid. |

Ahhh LS...that made me LOL! Thanks! :congrats:
Ummm...something about 'freezer burn?' :D Edit: Okay...I admit it...keeping gamey around has its value! |
@gamemanico
You've been here for 6 years and at videohelp for at least 1-2 years before this asking the same questions over and over and over and over. You're halfway through the projected 13-15 year lifespan of your discs. How many have failed during the past 7-8 years? If it's none or a small number, your storage methods are working. If it's a high number, then move! Nothing else is going to help! |
I just asked if storing the disks inside the ziplock bag with silica gel increases the life of the disks and if the zip bag contains any holes or does the opening become trapped inside the bag damaging the storage in the long run? if the bag contains hole the storage is the same as without using ziplock and silica bag?

I would suggest those sealable freezer bags.
And to be fair, it depends. I would say rather than being too concerned, I would keep them in the freezer bags, but save multiple copies on multiple different mediums. If you open them for viewing, renew the silica gel. We cannot give you a quantitative answer but if you are in a high humidity country, it will probably improve your discs lifespan, but no guarantees in life. So keep multiple copies if the data is really that important to you on different mediums. I for one, keep my video as digital files on multiple hard drives on/off site, DVDs and VHS tape. The lifespan of good quality video tape such as BASF/TDK properly stored has me convinced along with a few players and I still have some in use, multiple hard drives keeps me current with two here, one in a family member's safe, and DVDs for ease of viewing among others, spread out across true verbatim and M-Discs. The better stuff given out among people adds further copies. A cloud backup then for good measure along with the best stored as a copy on a 256GB USB key attached to my key ring. Photographs I print, and store in similar ways as mentioned above but without the tape. I also keep original negatives and print them using archival methods including proper fixing/washing and using fresh fixer etc. As much as you are trying to protect your discs, do not get too concerned. Just keep multiple copies on different mediums, and let it be. It is not like we can take this stuff with us when we leave this plane. |
If I put the mdisc dvd and dvd verbatim into the ziplock bag with silica gel does the ziplock bag contain any hole or any opening imperceptible will moisture get in the bag and have moisture condensation decreasing the durability of the discs??

Yes, that is always an issue. That is why experts recommend storing your DVD in the vacuum of space, where no humidity will affect it. UV radiation will do a number on the discs, but you can solve that by buying special lead-coated DVD jewel cases that they sell on eBay. To be on the safe side, also store in a lead DVD carrying case.

Orbital Science's Cygnus spacecraft costs about $43,180 per pound to send things up, not sure the costs of KEEPING it in orbit, and the subsequent retrieval costs if you should require one of those DVDs, but it's a starting point.

:smack:To put an additional scare into your fevered/demented mind, not only is the zipper seal not 100% air/watertight, but the plastic used in household sandwich bags are air and moisture permeable. :eek:
Ah....but you say, what if I put a bag in bag in a bag? Unless you're filling all the bags with an inert gas such as nitrogen, there's still atmospheric air in the bags. Also, the effects of nitrogen on optical media, AFAIK is untested (before you ask!).* *Oh...I know, I know, the next thread will be, "Nitrogen extend life of DVD in 30-35% degree humidity how long"? :screwy: Ah again...what if you vacuum seal the bags? Now you're forcing whatever material of whatever is against the DVDs directly into the surface of the disc, which may cause damage to the surface and warping. :depressed: Source: http://www.circuitnet.com/experts/86556.html And NO, neither I or anyone else here is 100% certain if what was posted incorrect unless they can produce a peer reviewed white paper on the subject/question: Quote:
