Abstract
A data storage device is provided which stores audio/video data to a disk media with a small amount of buffer memory and improves response with a reduced cost. Data transmission timing is known from a DMA request signal (DREQ) and a DMA acknowledgement signal (DACK). Therefore, audio/video data from an encoder can be directly supplied to an interface device without being temporarily stored in a buffer memory located before the interface device.
