The CD laser has to track the CD to find the data it needs. Also the laser moves much slower than a hard disk's head.

Hi You can store date either on CD or DVD without any restriction of time. Put the CD or DVD in Plastic cover and place it at a safe place in darkness and use it as anytime after no fixed period. Both the mediums are reliable enough. I personally experienced this. I recorded a CD ten years before and till today I use it.

hay man its depend upon on the Hard disk and CD/dvd rom drive.Which speed increases its performances is also increases

because hard drive is spinning at 7200+ rms constantly, while cd drives need to boot up and power up the spinner, and the revs dont go as high

The cd has to search for the information from start to finish, the hard drive is mapped.
