Writing to CD/DVD is a process that cannot be interrupted. When the writing is stopped (e.g. because no data is available, power is lost, etc.) the track is corrupt and cannot be continued. To avoid such problems, the writing can be done simulated or real. When simulating, all write operations are executed, but the write laser is switched off. If the writing procedure is discontinued, the CD/DVD is not affected and can be used after correcting the error. If you are not sure about the performance of your system you should always perform a simulation before you really write.
This method is available for nearly all CD recorders. The tracks are written step by step and the table of contents is written after the last track.
If you do not close the CD you can add additional sessions if there is enough space left. Another advantage is that the CD can still be used, even if a write error occurs.
Please note that an Audio CD player can only detect the first session. If you want to write additional audio tracks to a CD, you are not allowed to close the session after the fist write.
A disadvantage of this method is that it is not possible to write tracks without pauses between. Depending on the CD recorder the forced pause can be between 2 1/75 seconds and 2 seconds.
Using this write method, the data is written to the CD in one pass. This makes it possible to insert pauses between tracks. Please note that an Audio CD player can only detect the first session. If you want to write additional audio tracks to a CD you cannot use this method.
Using this write method, the data is written to the CD/DVD in one pass. This makes it possible to insert pauses between tracks. You cannot add any additional data to a CD/DVD written in this method. The greatest advantage of this method is the optimum utilisation of space and the option of using "DirectWrite as long as this is supported by the recorder. Tracks can be appended to one another without pauses.
Using this write method, the data is written to the CD in one pass. Unlike Disk-at-once where some data written to the CD is created by the CD recorder itself, in RAW mode all data is written by the program. This makes it possible to write data to the disc which otherwise couldnÆt be written. Since InstantDisc always creates the correct data, this feature is not needed in InstantDisc but in InstantCopy to create real 1:1 bit copies.
