Honest 836 Report post Posted April 21, 2008 ^^^ My dear Dr. Ali, their will be no harm to your music system if you play self made cd's or dvd's on it. But at the same time I would like to confirm you that low quality C.D.'s will definetely going to affect the lens of your music system. That's why try using only branded C.D.'s like Sony. Whenever you play cd/dvd, it gets hot. In low quality c.d.'s the media will starting to peel off from the c.d. when it gets hotter. And this media can very well damage the lens of your costly music system. Regards. Share this post Link to post Share on other sites
raccoon 53 Report post Posted April 21, 2008 Hmm, CD-RW or DVD-RW media are not as easy to read as commercially available CD/DVDs. They require much higher laser intensity to read. To that extent, it might (or might now... Im not absolutely sure), affect the life of your lense. CD/DVD-R media also, I guess, are not as easy to read as commercially available CD/DVDs... but better than RW media. Share this post Link to post Share on other sites

kshah 452 Report post Posted April 22, 2008 CDR/RW and DVD R/RW are difficult to read because they use dyed writable surfaces. They are photo sensitive dyes. Hence relective index of it is lesser than that of aluminum alloy foil used in punched CD / DVD , therfore more prone to read failures. It does not have any impact on lens and lens keeps safe distance from media surface. However due to any reason your CD / DVD has warpage, surely lens will get damaged. Thats the 1 of the reason why it is not reccomended to keep them in direct sunligh t / high heat areas. Share this post Link to post Share on other sites
raccoon 53 Report post Posted April 22, 2008 It does not have any impact on lens and lens keeps safe distance from media surface. Yes it keeps a "safe distance" from the media, but the lense has to work at higher intensity to read such media... and that is likely to reduce its working lifespan. Also, CD R/RW media are generally sensitive to light... not just direct sunlight! Keep them in cool dark places... Share this post Link to post Share on other sites

Also, CD R/RW media are generally sensitive to light... not just direct sunlight! Keep them in cool dark places... I was refering to physical damage. Intensity of laser do not reduces over a period of time as solid state laser do not age that fast, but due to constant vibrations in system and mechanical wear, focus gets blurred hence reading of medias become difficult. Focusing rigs cost lakhs so no service station has it, therefore even after changing lenses at times your drive or player do not work as original. Share this post Link to post Share on other sites
ssr 10 Report post Posted April 23, 2008 (edited) Yes I have also seen this when ever CD/DVD drives goes bad, just buy a new one it is waste to try to repair it For each media type and data layer different laser parameters are used to access/write. So the drive knows what is the intencity and frequency of laser must be used for a perticular media. rest of the reasons/precautions as per kshah's & Honest Posts Edited April 23, 2008 by ss_rakesh Share this post Link to post Share on other sites
