This topic has recently arisen, and I was wondering how exactly the two methods work. I was also wondering how max/min transfer rates are established. It is my understanding that CLV is used to increase data density, as it allows for constant data density throughout the medium, and does soo at the cost of performance(constant as well as overall). It is also my understanding that CAV is used in drives such as hard disks to offer better performance, at the cost of greater data densities. I was wondering more specifically whether audio cd's use CAV or CLV, as well as data cd's, or perhaps if both methods are implemented for data cd's. In addition could anyone tell me whether cd's use closed tracks as hard drisks do, or 1 or more continuous tracks as in the case of a vinyl record. I was also wondering about how exactly TrueX works. Further information on such technologies would also be greatly appreciated.
Someone told me that with CAV the bumps get farther apart on the outside of the disk than they are on the inside, allowing CAV to read at a constant rate. Can someone confirm or deny this? This person also said that data may be using CLV, and thus the variability of the speed of the drive results from the inability to maintain the max CLV towards the inner part of the disk. Is it possible that this is the case with hard drives and not CD's or vice versa.
Can anyone give me a more solid and in-depth answer, and possibly explain how exactly TrueX works?
BTW, are the tracks closed or are they a single continuous track such as the case of an old vinyl record?
