CD-RW Linux

UDF write support is experimental code in the Linux 2.4 series kernels.  Write support can be compiled in, but is neither there by default, nor safe to use.  if you DO choose to use it you must recompile your kernel and select experimental code, UDF Read support (which is not experimental and is stable), and the UDF Write support.

I have recomplied the kernel for UDF read / write option, but I am not able to write it. (read only)

What else I have to do, apart from kernel recomplie?

You will to use SCSI emulation in the kernel, or as a module, and using a SCSI device (emulate) to be able to write to it. In order to get it to work, you can use cdrecord (with option scanbus) to see if you have done everything right. If it shows up in the list of SCSI (emulation) devices, you will be able to write to it.
