Virtual Blanks

To use the virtual CD burner with an application that writes CDs, you have to insert a blank CD, just like you would in a physical CD burner. This is why we have developed the virtual blank, which is a special type of virtual CD. Strictly speaking it is a virtual CD that does not contain any data, and which can only be used in the virtual CD burner.

Virtual CD supports a broad array of blank media types, some of which differ only slightly from one another. Almost all types of blank, in both write-once and re-writable forms, from CD-R to Blu-ray-RE DL, can be created and written to with a virtual burner.

With the exception of re-writable media, all blanks can also be created as ISO-compatible media. Thus if the medium is later burned onto a physical disc, it is compatible with any program that can process ISO images.


One of the main problems with using virtual blanks is that their data capacity is not known in advance. Virtual CD analyzes the file system on the hard drive on which a blank is created. If the hard drive uses a file system that puts restrictions on file size (e.g., the FAT32 system), then the blank is divided into separate sections. It is not possible, however, to divide ISO blanks this way, as this is not provided for in the specifications for ISO images.



Even though virtual CDs are automatically divided when they are created on system with file size restrictions, it may take a long time to make re-writable media, as their full capacity is already defined as they are created. For this reason, we recommend creating blank virtual media on a computer with an NTFS hard drive.
