Problems solved by technology

However, the device that encodes data with a multiplexer MUX cannot efficiently encode data into fixed packets 10, which further affects the overall programming speed
[0008] All in all, when the known technology burns data in a fixed packet mode, it cannot efficiently encode the data into a fixed packet, and may even cause a programming error, affecting the correctness of the burned data

Embodiment Construction

[0025] Please refer to figure 2 , figure 2 It is a schematic functional block diagram of the burnable optical disc drive 20 for automatically encoding fixed packets in the present invention. The burnable optical drive 20 is provided with a processing circuit 22 , an encoding module 24 and a burning module 26 . The processing circuit 22 includes a control module 23 , a temporary storage device 28 , a counter 30 , a counter 32 and a comparison circuit 34 . The control module 23 controls the operation of the processing circuit 22; the temporary storage device 28 is used to temporarily store the data output by a data source 36, and is controlled by the control module 23 to output the temporarily stored data to the encoding module 24; the counter 30 records a The block count W0 should be encoded, and the counter 32 records a block count B0 to be encoded; the count W0 is the total number of blocks of data to be written, and the count B0 is the total number of blocks of data rece...

Abstract

The present invention provides one kind data baking method to code data as one sequence of fixed packages automatically and relative baking CD drive. The present invention has one first counter to record the block number of data to be baked and one second counter to record block number of data to be baked and un-coded as fixed package, and can treat data fast without need excessive time in generating fixed package, reduce the probability of inadequate data in the buffering memory of CD-RW drive and reach fast and correct coding.

Description

technical field [0001] The present invention relates to a method for burning data in a fixed packet mode and a related burnable optical drive, in particular to a method for quickly encoding the data to be burned into a fixed packet by using a counter to count unencoded data and the related burnable optical drive . Background technique [0002] In the modern information society, optical discs, which are small in size, light in weight, high in storage density and low in cost, have become one of the most popular non-volatile storage media. Since the popularization of high-speed CD burners, the problem of buffer data shortage (Buffer Under Run) has been troubling all burner users. Simply put, the reason for Buffer Under Run (Buffer Under Run) is that the programming speed is greater than the flow rate of computer data. When starting a burning job, the burning program will read the data to be burned from the hard disk or another disc, temporarily store it in the buffer of the b...
