Abstract
A method for transferring data from a large capacity data storage device to a host machine. The method requires the attachment of a plurality of SRAM memory blocks to an optical disk reader. Each SRAM memory block is used as temporary storage area got a sector of data so that data can be proofread one sector at a time. As soon as the entire sector is checked and corrected, the error-free data is transferred to an external DRAM memory. Thereafter, correct data can be read from the DRAM by the host machine at any time. The internal SRAM memory serves as a buffer holding sectors of data so that error detection and error correction of individual sector can be carried out. Additionally, the external DRAM memory serves as a buffer holding the correct data for the host machine.
