CDROM block device driver


Hello, I would like to develop a block device driver for a CDROM device which is controlled through I2C and the data from the CDROM is read through S/PDIF. I understand that in my driver request() function, after finding out that it is a READ request, I have to read a certain size of data ( Give a I2C command and then read using the S/PDIF driver). My query is should I have to pass this data as it is to the File system driver or do I have to do process this data before sending the data to the File system driver?

Thanks and Regards,
Souvik
