CD-R Features
Large Capacity Recording
As voluminous an amount of data as about 650MB can be recorded on a single disc. (74 minute disc, recorded in mode-1)
This amounts to the capacity of nearly 450 floppy discs.
CD-ROM Compatibility
The recorded CD-R can be read with a CD-ROM drive. Therefore, if data is recorded on a CD-R, it can be accessible everywhere in a easy way. Recently, most of desk top PCs are equipped with a CD-ROM drive, which has very high propagation rate.
CD-R Cost Merit
The memory storing cost is around \2 per 1MB, which is very low compared with other discs.
Amid an explosive increase in information handled by PCs, this prominent cost-performance results in high merit.
Security
Data, once recorded, cannot be physically erased.
This characteristic prevents data tampering and/or risk of erasing by mistake, making CD-R optimal for archiving of data and documents.

High Reliability
During recording and playing back, the optical head never touches the CD-R media surface. This feature prevents the disk and its stored information from being damaged.
CD-R is suitable for long term archive of data, because it is not necessary to rewind them for storage and maintenance, as is the case of magnetic tapes.

Random Access
With CD-R, high speed random access is possible, enabling quick retrieval of the target data from the data base.
Cost and Safety Advantages in Distribution
The recorded CD-R is easy to handle and transport by mail, like a CD.
It is not necessary to protect it from magnetic fields during transportation.
To transfer a large amount of data by personal computer communication or Internet would be costly.
However, physical transportation, such as mail or express, ensures low cost.
Therefore, the CD-R is an optimal choice for distributing a great deal of data at least expense.
