Module X is the data grabber, which reads computer data from LV-ROM discs. Data is divided into blocks of 2048 bytes, and each block is read in 1/75 of a second.

An LV-ROM disc revolves at 1500 rpm, or 25 revs per second, the same rate as a CAV disc. The player reads one frame per disc revolution, or 25 frames per second, meaning each frame is read in 1/25 of a second. It follows therefore that the player can read three blocks per revolution, and player locates each data block with reference to the frame number, so the location of a particular block is calculated by dividing the block number by three to give the frame number.
