1477.0. "What can/cannot harm CD's?" by FGVAXL::LAING (Soft-Core-Cuddler*Jim Laing*261-2194) Fri Jan 13 1989 07:28

    I can find no discussion of this particular topic, so I thought
    I enter a new NOTE.  What substances can/cannot harm a CD?  I've
    been watching ads for "newfangled" storage devices (those that don't
    use Jewel Cases), and some say " ... our device uses no harmful
    plastic pockets ..." while others ARE plastic pockets!  Of course,
    there are lots of kinds of plastic.
    
    One company, UNIVENTURE, has a storage system that looks like a
    photo album - on the left, pockets for 4 CD booklets, on the right,
    pockets for 4 CD's.
    
    DISCover co. has a holder that's a "liner" that you slip the CD
    into, then this goes into a plastic "sleeve".
    
    Blakeman Enterprises' DISC-GO is a "take 'em with you" wallet-ish
    thing that holds 20 CD's, again in some sort of plastic "sleeve".
    
    Can these be potentially harmful to CD's?

1477.1From what I gather.....treat them like lp's!VEEJAY::ECTORChicago blues=Bears loseFri Jan 13 1989 12:0525
    
    
    I'd think that anytime you put "soft plastic" (as in these sleeves)
    next to laquered, plastic coated aluminum (discs), you have to be
    concerned about a few things. Heat, for one....considering that
    soft plastic WILL stick to discs, thus making it difficult to pull
    the disc out and making it accesible to damage. Another is cold
    - which hardens the "soft" plastic sleeves, allowing for the same
    possiblity. Beside all that, soft plastic has a tendency to sweat,
    and I'd think that a damp environment for discs wouldn't be good.
    
    I'd stick to the jewel box and those storage devices that are made
    for the jewel box to fit in (including carrying cases).
    
    CD's basically are susceptible to the same damages incurred by lp's
    - scratching and warping. Handle a cd as you would an lp - by the
    edges & in the case of CD, you can also touch the center hole with
    no adverse effects. Don't use them for mini-pizza trays, leave them
    in direct sunlight or leave them out to collect dust. Blow lint
    off and for finger oil, etc., use only a slightly dampened, no-lint
    cloth and lightly sweep from the center out.

1477.2Jam on itWELMTS::THOMPSONOh He With BRIGHT Tie (:-)*- Tue Jan 17 1989 04:1212
    I have found that even fingerprints can degrade the playing quality
    of the CD so i invested in a cleaner from W.H. Smith (uk shop) that
    uses a spray and then a circular motion cleans the disck with a
    supplied pad this cleans the cd and removes any marks such a grease
    or general finger marks. also i have found scratches by just putting
    the cd into the player . I was under the impression that you could
    play a CD with jam on it (iam not sure if jam is the write term
    for the States) so I know look after my CD colletion with kid gloves
    and store them in the origional package.

1477.3where's the data?HPSTEK::BROWNTue Jan 17 1989 11:289
    
    Whilst on the subject of marks, fingerprints and other surface
    blemishes, it has suddenly dawned on me that i don't know which
    surface matters!
    Does anyone know if the information, or "tracks" are on the same
    side of the disc as the writing, or the plain side?

  All the music information is read through the clear side (no printing).  

1477.5PROTECT THAT LABELFREEBE::RIEGLETue Jan 17 1989 16:025
         The foil layer on which the information is recorded is read
    through the clear side.  However, the foil layer is very close to
    the "label" side.  A scratch on the lable side is more likley to
    hurt the foil.  I belive this is done so that small blemishes on
    the clear side will be out of focus when the disk is read.
