What are the disadvantages of optical storage?

By optical, I'm assuming you mean CDs and DVDs.  The drives that read them are optical drives.  The only disadvantage I can think of is the possibility of less throughput than other means of storage.  And, of course, they are likely to become scratched.  This is all improving though, with the introduction of HD-DVD and Blu-Ray media.  The drives that read them have to handle a lot more data, so the amount of data they read in a given amount of time is a lot more than that of traditional optical drives.  There is also an improvement on the physical makeup of the disks that makes them a lot harder to scratch.  I hope that answers your question.

Will do no harm at all - it is simply using the drive lens in the same way it would normally to write data, only that it is scrubbing the disc instead.

those are unrepairable, you system might still be able to read most of the disk, but if you can actually see through the disk in spots that data is lost.

Minimum 10 years - probably closer to 15-20.\n\nThe technology is not nearly mature enough to support affordable mass production, and there is no real consumer demand - as long as PC's continue to become more powerful and less expensive with current technology.\n\nI could see optical computing reaching the high-end server market sooner - maybe in the 10-15 yr range.

Flash Memory Thumb Drives and USB External Hard drives.  That's where it's at today.   Double Layer DVDs are cool, but don't come close to Flash and hard drives for quick access, transportability and awesome backups.\n\nGood luck and Happy Computing!

Electronic: extremely fast to store and retrieve information, but most are "volatile", i.e. lose the memory when the power is turned off.  Capacity is the lowest of the three, usual maximum in a PC is 4Gigabytes.  Most expensive of the three.\n\nMagnetic: very fast store & retrieve; information density high, so does not take much space; Capacity much larger than electronic, typical max capacity on a PC is 1000 Gigabytes.  Moderate cost.\n\nOptical: moderately fast to store & retrieve; very easy to remove optical media for safe storage in a separate building.  Lowest cost per gigabyte: a DVD-R costs 25p for 4Gigabytes.

you can use a diskspacer that doubles the capacity of your flash drive (it compresses existing files and increases logical capacity) but reduces access speed drastically. i wouldn't recommend it since flash drives are meant for fast file transfers via USB.

Disadvantage\n\n1)It looks bad to customers, they think ur in problems thats why you have to factor debts\n2)Charges\n3)\n\nAdvantages\n\n1)Reduced risk of bad debts\n2)Dont have to have debt collection staff\n3)Easier to plan cash flow\n4)Protection against currency movements\n\n\nSorry cant think of any more disadvantages

The one thing you need to check in is a data CD-R, or DATA DVD-R. DVD-R will give you better buring options and increase the clarity of your pictures once transfered from your computer to a cd. Also another good source of storing media (any type) would be an external drive or flash drive. A flash drive is compact, light weight, and easy to use. Check your local wal-mart to find and of these items.

Assuming that the optical drive is a DVD player, you may require additional software. PowerDVD is available at quite a low price.

USB External hard drives are very affordable and have the advantage of being portable. Another alternative is copying your data to a DVD(s). Then store them offsite in case of a fire or other disaster.

Current CD-ROM players use an invisible-light infrared laser with a wavelength of 780 nanometers.\n\nHowever, as another poster mentioned, this varies especially in RW drives.

I can think of only 2 disadvantages to digital, and the first relates only to a niche market.\n\n1. You can't make projector slides. (but you can display your pictures on a tv or pc, so why bother with slides?).\n\n2. You get a very small shutter lag (delay between pressing the button & the camera taking the shot). Usually only a fraction of a second, and virtually non-existent on some hi-end digital cameras.\n\nAdvantages include being able to review photos as soon as you've taken them. No wastage if the photo is no good - you simply delete it - very handy if you're practicing. Memory cards have much higher capacity than photographic film. You can shoot continuously until your batteries die - no film to change. You can send your pictures anywhere in the world in seconds via email. You get discretion - no need to send your films to a processor. You can store your pictures online (using web hosting) meaning you'll never lose them.\n\nIs that enough?? :)\n\nEDIT: In response to the other guy, memory cards are no more expensie than film given the capacity, especially given the reduced developing costs. my 1gb card is good for about a thousand hi res pics it cost £40 - that's 4pence per photo AND it's re-usable AND it's virtually indestructible.

It will hurt!\n\nAn 8x recordable speed disc is only designed to be recorded at 8x speed.  Any faster, and you risk producing a bad recording, with the chance of errors and unreadable sectors increasing the more you exceed the rating.  Unreadable sectors give you lost data, or drop-outs in audio/video.\n\nAs for reading discs, that same disc rated for 8x recording might also be rated for 16x or faster reading, once you've recorded your data.\n\nOn a related note, if you're concerned with quality, choose the manufacturer of your DVD media well.  Not all recordable DVD's are created equal, and you will have poor results with some cheaply manufactured media, regardless of the speed.  In general, the DVD's manufactured by certain Japanese corporations offer the best quality today (2006).

The Pros: \nLCDs are Compact, sleek and stylish.\nLess strain as there is no Radiation.\nU can fit a bigger Screen for the same space.\nless power requirements.\n\nThe COns:\nExpensive\nFragile\nSlower refresh rates make it less utility for High speed action games/motion/animation or fine test, Video/image editing. But they r getting better.\nThey need careful handling.

Assuming that your CD Drive file letter is G, then I would say that you do not have a recordable optical media drive (also known as CD Writer or DVD Writer) which is why it is showing no free space. Because actually, you can't write on it!
