[Prior Art] Fig. 1a is an architectural diagram of a Blu-ray disc device. The blue light 1 device 100 includes a memory array 12' as a buffer for data input. The optical disc drive 110 basically includes a plurality of read/write heads (Ρυκ〇 related control units for accessing a Blu-ray disc (not shown). Recording frames taken from the Xueguang discs #R through the disc drive 110 Stored in the memory array 12A, and in contrast, the recording frame #w to be written to the optical disc is transferred from the memory array 12 to the optical disc drive 110. According to the Blu-ray standard, the data stored in the Blu-ray disc is stored. ^ Protected by a complex and robust error correction technique. The encoder adds the wrong block correction code to the input data #IN to generate the record frame. The relative record frame read from the monitor CD is decoded by the decoder 14〇. In order to preserve the integrity of the data, the output data is generated as #〇UT. Therefore, in the operations of mastering, writing, encoding and decoding, the memory array 12〇 plays a key role β Μ 1 b is a light A long-distance code () block 160 specified by the standard. - LDC block 160 is a data unit of ~ kinds of entities, which is established from the original data through a complicated encoding process, which contains -2 (2 he + 2) Called 38) E CC (C1 her r) / intermediate interval 0758-A32124TWF; MTKI-06-130; yeatsluo 5 1345765 Position interspersed with three (216x2+32x2) xl BIS code. Basically the Ε (χ box is via data The block and rS code are interleaved, and the operation rules can refer to the Blu-ray standard file, so it will not be described in detail here. Traditionally, the LDC block 160 is horizontally oriented in the memory array 120 (relative to The memory array 120) is generated row by row. However, from the viewpoint of the Blu-ray disc, the LDC block 160 can be regarded as 496 155-bit recording frames arranged in the vertical direction, wherein each of the 31 recording frames is also called a The physical sector. When the recording frame is ready to be written to a Blu-ray disc, the disc drive H U0 sequentially reads the recording block in the vertical direction for the modulation and writing process. In other words, in the design of the Blu-ray disc, The direction in which the disc drive 11 〇 processes the LDC block 16 和 and the encoder 13 〇 and the direction in which the decoder 140 processes the LDC block 16 相互 are perpendicular to each other.

First, sequentially and along a first direction, a recorded frame Θ The virtual order memory array is then processed in the memory array according to the second direction, and the second frame is processed. After processing, the memory array is released in sequence. At the same time as the release step of the first-stage squeeze, the plurality of second records are sequentially read from the CD-ROM and from the memory array. And the direction is written into the L-hex-length== the first-command-to-matrix (LDC) block in the body array, including the complex data column along the line. The processing step includes sequentially discharging the side of the first body array along the eleventh body array perpendicular to the second direction. The first direction is further, when the first LDR is After F decodes and outputs, it uses one of the second records in the -data column to be used: :^ , · The memory that is released is 8 〇 758-A32124TWF; MTKI-06-130; yeatsluo / Another embodiment proposes a Blu-ray disc writing method.

The decoding sequentially decodes the second >LDC region The data columns in the block and the decoded data are output. To achieve the above and other objects, features, and advantages of the present invention. The following is a detailed description of the preferred embodiment, and is described in detail with reference to the accompanying drawings: • [Embodiment]: How to implement the present invention in a better manner. The detailed examples are only for the purpose of explaining the general application, the scope of the application. The actual scope is based on the scope of the patent application scope =: the use efficiency of the strong 3 memory, and the reduction of the memory between the present invention proposed a new memory Figure 4a is a read step 402 of one embodiment of the present invention in which the above-described reading step is performed from the disc drive until the complete LDC region is formed: block 16. From the gamma direction It appears that a plurality of data series (four) are listed. In step Mei, the data string in the S-station block 160 is decoded. In step 408, the decoded resource & output to an external interface, such as a computer host. Basically, the second step is to use the pipeline multiplex method/squeeze and after the space occupied by the field, the decoded poor material output Ρ is released, and a row is generated along the γ direction 0758-A32124TWF; MTKI-〇6 -13〇;yeatsluo 10 1345765, Then, steps 41〇 to 416 are similar to the steps, and the direction of use of the memory is turned by ninety degrees. In step 41, 2, a plurality of second records are read from the disc drive no, and It is written in the memory array 12A in the U direction. Thereby, step 41〇 can be executed immediately after the memory station that is idle after being released is used immediately, the overall optical disk reading performance can be improved. The 412 continues to recursively read, and the LDC block 16 Q has a plurality of data strings arranged along the X direction. Then, steps 414 and 416 can be performed simultaneously, along the x direction. The data string is decoded and output. Finally, the entire program is repeated 402. Yb Figure 4b is a write procedure of one of the embodiments of the present invention. The same concept of the direction of use of the memory can be applied in the write program step 422, the plurality of first input data_from the external input and along the I^ direction: the memory array 12" exists. In step 424 , code: two = the input data is encoded, and the encoded data is stored in the same position, and, in the step, the above input and encoding work is continued until the formation - LDC block 16 () This [DC block (10) contains a plurality of record blocks arranged along the 乂 direction. Then in the step like, 'sequentially record the (4) people in the blue light (four). Every time it is successfully written - _, it is along the X direction The occupied memory is released: a line-free space is formed. Steps 43A to 436 are similar to step 422, but the direction of processing has been turned by ninety degrees. In step 430, multiple numbers are input from the outside. The two input data engineers store 0758-A32124TWF; MTKI-O6_130; yeatslu〇11 f memory array 120 along the X direction. Step 430 can be performed synchronously with step 428, and the gp ϋ田 4 v, i 1D uses the x The space between the directions. Therefore, the memory array mother The time of one column of idle time can be shortened, so that the overall utilization rate is increased. In step 432, the input data #IN is input along the X direction to 'flat code. In step 434, the encoding step is continued until the next LDC is formed. The block 16〇 includes a plurality of record frames arranged along the γ direction. Next, in step 436, the record f in the LDC block (10) is sequentially written into the Blu-ray disc, and the entire process returns to step 422.
