What is a erasable disc

First of all, in fact, we habitually called the removable disc, is erasable CD-ROM. (See the introduction below)

The most important function of Erasable CD is that it can erase data and write new data.

Then the general CD-ROM 1.5~2 yuan more than one, can erase CD 10~15 bar. Data that requires long-term recording with a CD-ROM, short term data or files

Introduction to Erasable CD

The advantage of a erasable disc relative to other discs is that you can use the software to erase the data and reuse the disc after burning. The number of theoretical erasure can be up to 1000 times, but due to the storage environment and wear and other external factors constraints, the actual number of erasable can not be reached more than 1000 times.

Now the general Erasable disc has DVD-RW,DVD-RDL,CD-RW. Their capacity is about 4.7g,8.5g,700m, respectively.

The principle of erasable disc

The disc has a structure of six layers, recorded in the phase-change metal (Hase-changemetalalloylayer), is a highly reflective crystal structure, in the burning of data CD-RW using the highest power laser at the location of the burning data 1 heat, the small area of the alloy material melting, It can then condense into amorphous tissue so that it does not have good reflexes as it did, as for the recovery of the crystal structure, as long as the medium-power laser can produce enough temperature to restore the amorphous tissue to crystalline structure using CD-R discs for a moment.

How to use Erasable CD

1. Use like a CD-R

can be inscribed CD, VCD (CD, VCD can only one entry can not be duplicate, MP3, data disk, etc., the use of methods and CD-R exactly the same, in the capacity to allow and set the correct circumstances can be written several times, but the original content can only be screened delete (also can not delete), delete can not increase capacity.

2. Use like a floppy disk

According to the reusable features of CD-RW, we can format it with a dedicated formatting tool, and then we can use a CD-RW like a floppy disk, and you can add capacity (or not delete) by deleting the original content, but this state cannot burn CDs, VCD, because CDs, VCD has its fixed format, a CD or VCD after the original format of the information and has entered the content will be automatically deleted, this is a CD, VCD can only be entered into the cause of replication.

How to do non-removable disc to burn multiple times?

The first thing to make sure is that you use a CD-R that is multiple orbitals (as you can see in the NERO6), and then do not "end the disc" Every time you burn it, as long as there is enough space left inside to burn it. So, in fact, is not to scrub the disc erase, but continue to burn.

It is OK to continue adding files on the non-removable disc, I use the Nero burning software, in the final burn option to determine the "Allow to add files later" hook to hit. The first steps are the same the next time you want to add a file, but before you burn the software prompts you to select n when you delete the previous file. The way to do this, however, is to waste about more than 10 trillion of space (which is used to link files) rather than wasting all the remaining space. But be sure to consider how much of the more than 10 trillion that is used to connect, and how many more can be used next time.

How to wash the contents of a removable disc

In the Nerostartsmart interface, click on CD or DVD features, "Other" under the Select "Erase Disc", to determine the way to erase the point "erase" can be.

For burning the CD-ROM software, we recommend the use of Nero, I used to burn the CD, but in the U. S cheap today, you can use your removable hard disk instead.
