The contents disclosed in this patent application The system is fully integrated into this specification. μ [Technical field to which the invention pertains]

One invention relates to a disc recording, and more particularly to a disc reproduction and recording test. [Prior Art] In general, a disc reproducing device such as a CDP (disc player), a DVDp (digital video disc player), a CD_R (writable disc), a CD disc (a dual-disc disc), or a DVD-R0M (only Reading the video disc), launching a laser onto the spiral on the screen to read the reflected laser beam and reading the audio or video information contained in the reflected laser beam. The audio or video information is encoded in the form of a sag or a mark and a blank pattern. In them

=Measuring allows the user to count the message or the video recording. The disc recording and reproducing device is tested before leaving the factory to check if our recording function works normally. Figure 1 illustrates a conventional handle record and re-graph. Referring to the drawing, the disc recording and reproducing device touches ' " Han 贝 Be taken early 70 130 (it reads information from the disc). Qinguang

The Hi device _ further includes a radio frequency (rf) unit (not shown and a digital W processor, tree). The RF unit is turned by the read unit ~I2964Q72_. . 130 converts an rf signal read from the optical disc into a stream of one digit. The digital signal processor processes the digital stream and generates an audio or video recording unit 1 ίο receives the data to be recorded from a host computer through the high-end technology add-on packet interface (ATAPI) 111, and The address to be recorded is stored in the buffer memory 丨2〇 by the address specified by the memory interface 112. The data stored in the buffer memory 120 is audio or video information recorded by the user during normal recording. In the abomination process, the memory interface 112 of the recording unit 110, the first encoding source 113, the memory 114 (such as static random access memory (SRAM)), and the second encoder 115 are encoded in a predetermined format. The data to be recorded stored in the buffer memory 120. A write strategy unit 117 generates a signal for driving the laser diode (LD) of the reading unit 130 using the encoded data so that the LD emits the laser beam onto the track on the disc and records the mark and Blank type coded information. When the first encoder 113 encodes the data, a data header • header error correction (ECC) parity or error detection code (EDC) parity bit is added. During the recording test, the test pattern generator 118 outputs the test data, and the test data includes a predetermined pattern for testing. Test data with a predetermined pattern to be recorded on the disc for testing is stored in the pattern generator 118. If the test data is output, the test code unit 117 encodes the test data, and the write strategy unit 117 generates a signal for driving the LD of the read unit 130 using the coded data. The second encoder 115 is programmed with 8 6 • I2964Q37pif.doc code test data, between (A TIP) and μ; then the 5 type lean material can be based on the pre-groove absolute time. When the second time 16 generates the disc timing information (DTI), it is written into the standard (^^^ 仃 > material merge or modulation. In the test, the test is performed on the recording and testing of the regenerative device 1GG: the test, the optical power calibration test, or the 117 ^^^^^Cseparate circuit, and the internal SRAM. 114. Another example is disclosed in U.S. Patent No. 6,661,481. Here, the conventional optical disc records and the long mark data generator of the i = == object generator 118 to generate test data to be recorded. The recorded test data is converted by a predetermined modulation process and then used for a write strategy. Therefore, the optical disk recording and reproducing apparatus disclosed in U.S. Patent No. 6,661,481 is similar to the conventional optical disk recording and reproducing apparatus 1 of Fig. 1. However, the test pattern used by the conventional optical disc recording and reproducing apparatus to generate test data by using a separate circuit is relatively simple. Although it is possible to use test hardware with a more complex configuration to increase the test pattern = quantity, the cost of implementing these increased number of test patterns is also advanced. Therefore, due to the corresponding increase in cost, the implementation of flexible recording tests is limited. Also, although the internal sram ιι4 is used to increase the number of test patterns, the length of the test pattern is limited by the size of the sram 114. SUMMARY OF THE INVENTION A feature of the present invention is to provide an optical disk recording and reproducing apparatus which can improve the flexibility of a test pattern, ensure a sufficiently long test pattern, and pass bypass. Test data stored in a static random access memory (SDRAM) buffer to conveniently check the recording status. Here, the test data is extracted in a vocal digital sound (cd; ^ or similar to CD_DA). The bypass tribute is used for the writer strategy towel that does not S-code operation to generate - A polar body (LD) driving signal. Another preferred embodiment of the present invention provides a technique for driving a light recording and reproducing device, which can improve the flexibility of the test pattern, ensure a sufficiently long test pattern, and is convenient. In accordance with a further feature of the present invention, the present invention provides a regenerative device that includes a sample of a lyrics, a lyric, and a recording 70, for receiving a record to be recorded. Bessie. The data to be recorded is encoded in the first recording mode (10) de) to generate a laser diode driving signal, and the data to be recorded is in the second recording mode, in the case of no encoding. It is bypassed to generate a diode drive signal. The apparatus further includes a reading unit that reads the encoded information on the i-beam, and records information on the disc formed by the second:=two: Huya. The disc is recorded and reproduced: the 8th and 5th fields are recorded, and the memory stored in the memory is recorded from the main computer by the heart of the record. The recorded data is recorded to the recording unit. (4) The output will be 596412,1. In another feature of the present invention, the recorded disc-digital sound format is input from the host computer and can be stored in the buffer memory in a disc format, and Bypass-encoder bypass=曰 can be a disc-digital sound format. If it is to be recorded _: # material in the buffer = memory is read when the - non-return to zero (NRZ) pulse format of the number of

The serial data can also be a digital signal in a non-return to zero pulse format. Conversely, if the data to be recorded is a digital signal in the zero-inverted (NRZI) pulse format when the buffer clock is read, the serial data can also be a digital signal that does not return to the inverting pulse format. According to a re-characteristic of the present invention, the present invention provides a method of driving a disc. A recording/reproducing method includes receiving a material to be recorded; in the first recording mode, the encoding is to be recorded # It is expected to generate a laser to transfer money, and in the second note, the bypass will be recorded, and the bedding ' ▲ will be generated without coding - the laser diode drive letter ^, should F shot the pole lion to move money, and passed in the recording process. The device for taking the order S forms the encoded information on the disc, the laser beam is emitted onto the disc, and during the reproduction, the encoded information on the disc is read from the reflected laser beam by the reading unit. The method is more likely to include storing data from the =3⁄4 input to the buffer memory; and reading the data stored in the buffer and outputting the read data as the material to be recorded during the recording process. The above and other objects, features, and advantages of the present invention will become more apparent from the understanding of the appended claims appended claims I2964fl72p, d〇c [Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings. 2 is a block diagram of an optical disc recording and reproducing apparatus 200 in accordance with a preferred embodiment of the present invention. Referring to FIG. 2, the optical disc recording and reproducing apparatus includes a recording unit 210, a buffer memory 22, and a reading unit. The track recording and reproducing apparatus is capable of reproducing the second encoding information and can record the required information. A digital device on a disc, such as a writable compact disc (CD-R) or a rewritable compact disc (CD_RW). * #When the recording process is performed, the recording unit trains the information to be recorded and generates a laser diode (LD) driving signal according to the predetermined write strategy. The reading unit 230 responds to the LD drive signal and forms a coded pattern of the standard and blank on the disc. Here, the coded pattern represents the data on the disc that will be recorded. μ After the reproduction process is performed on the disc, the reading unit 23 emits a laser beam onto the disc, reads the encoded information on the disc from the reflected laser beam, and generates a radio frequency (RF) signal. An RF unit (not shown) converts the RIMf % number into a digital stream. A digital signal processor (DSP, not shown) decodes the digital stream output generated by the RF unit during the reproduction process, and converts the decoded digital stream into a signal that drives the audio system or the video system. Accordingly, the user can listen to or view the encoded information on the disc through the audio system or the video system. Further, the reading unit 230 includes a focusing actuator (not shown) and a tracking actuator. The focus driver moves vertically under the disc so that the laser beam emitted by the LD is accurately focused on the disc. Tracking driver

I2964iQZPifd0C ==The center of the disc is moved horizontally in and out so that the laser beam can be accurately typed. The normal recording mode and the recording test mode MODE (: Fig. 2; to::: record test mode pass - mode selection signal fi side selection. When the user records the required reduction on the disc, select the g sad record mode. Yu Yuzhi, who is in the market, or who is in the market, chooses to record the test mode when the product is ready to be recorded on the disc. The upper=test mode is more likely to be used for verification—whether the circuit in the recording path and the pi:疋 write strategy are correct. In particular, the write strategy unit 217 shown in record 2 is optimally driven (4). The write strategy unit 217 determines the power of the LD laser beam so that the LD supplied by the reading unit 230S can properly form marks and spaces on the disc. The operation of the writer strategy unit 217 will be further explained with reference to FIG. The recording unit 210 receives the material to be recorded from the buffer memory 220. The buffer memory 220 is placed outside the recording unit 21, which stores the material to be recorded. The buffer memory 220 passes through the interface of the recording unit 21 From an external host computer The data input is input, and the data to be recorded is outputted to the recording unit 210 during the recording process. The buffer memory 220 may be a synchronous dynamic random access memory (SDRAM). The recording unit 210 records in the normal state during the recording process. In the mode, the data to be recorded is encoded to generate the LD drive signal, and in the recording process without the encoded data, the data to be recorded is bypassed in the recording test mode to generate the LD drive signal at 129641. Referring to FIG. 2, the recording unit 210 includes a high-end technology attachment device packet interface (ATAPI, hereinafter referred to as ATA packet interface) 211, buffer memory = interface 212, first encoder 213, memory 214, second tarcode, pre-groove absolute Time (ΑΤΙΡ) interface 216, write strategy unit ° 217 synchronization device 218. ϋ The user inputs the data to be recorded to the recording unit 210 through the host computer. The packet interface 211 is between the host computer and the recording unit 21〇. Interface. A Τ Α packet interface 2 丨丨 output the data to be recorded to the buffer memory interface 212, after the buffer memory interface 212 receives the data to be recorded, it The buffer memory 220 is taken and stored in the buffer memory 22'. During the recording process, the first encoder 213 accesses the buffer memory 220 through the buffer memory interface 212, and reads the first code of the data 7 to be recorded. In the normal recording mode, the device 213 adds information including a header, an error check correction (ECC), and an error detection code to the information frame of the data to be recorded, and outputs the first code. Data, % to perform the first encoding operation.

However, the first encoder 213 bypasses and outputs the material to be recorded in the recording test mode. Here, especially in the recording test mode, the data to be recorded is input from the host computer in a disc-digital sound (CD-DA) format or a data format similar to the CD-DA format, and is in CD-DA format. Or a similar format is stored in the buffer memory 22〇. The bypass material DAD is also output in the CD-DA format or the like. Here, the difference between the CD_DA format and the CD-ROM format is that the header, ECC, EDC 8 12 1296mu, and the like are not added to the information frame of the CD_R0M format. Thus, the CD-DA format is a user profile format containing audio and video information corresponding to the content to be recorded. In at least one preferred embodiment of the present invention, the bypass data dad has a CD-DA format; the first encoder 213 and the second encoder 215 do not encode the bypass data DAD; and the write strategy unit 217 is bypassed. The data DAD drives the LD. Drive signal. By way of example, the conventional optical disc recording and reproducing apparatus shown in Fig. i, or as disclosed in U.S. Patent No. 11,11, </ RTI> does not have cd_da. And used to write the policy after being encoded in a predetermined manner.念田! The data to be recorded has the cd_da format and the unwritten code unit 217's writer strategy, the job record = the code-read is stored in the memory 214. Memory can be == static random access memory (sram). The second encoder 215 accesses the --214 and reads the first encoded data; and uses the = slice = sequence information DTI indicating a position on the disc to perform a first, flat code by merging, patching or modulating. And outputting the second encoded material. The disc is generated by the ATIP interface 216 in the order information DTI. The Ατιρ II. Hh丨Λ processes the jitter β γ /仏旎WS ′ indicating the current track position on the disc and generates the disc timing information DTI. ΑΤΙΡ Information in the track on the disc ’ and the disc timing information DTI is generated by =================================================== Therefore, the current track ^ 表示 represented by ^ ^ and from the center of the concentric circle is determined. Typically, a one second interval consists of approximately 75 8 13 1296 f.doc information boxes.

The write strategy unit 217 generates an LD drive signal based on the second encoded material in the normal recording mode. The write strategy unit 217 drives the LD drive signal based on the serial data of the bypass data DAD in the recording test mode. The bypass data DAD is converted into serial data by the synchronization device 218. The serial data is a digital signal with a non-return-to-zero (NRZ) pulse format or a non-return-to-zero (NRZi) pulse format. The NRZ and NRZI pulse formats are well known. The NRZ pulse format is a digital signal format that converts from low to high or high to low to represent one bit; while the NRZI pulse format is another digital signal format that uses only one clock cycle for the high state pulse width of the NRZ pulse. (clock cycle) to indicate. Here, if the serial data is a digital signal in the NRZ pulse format, the data to be recorded input from the host computer and

The data to be recorded read by the buffer memory 220 is also a digital signal in the NRZ pulse format. Also, if the serial data is a digital signal in the NRZI pulse format, the data to be recorded from the host computer and

The data to be recorded read by the buffer 220 is also a digital signal in the nrzi pulse format. 3 is a detailed block diagram of the synchronizing device 218 of the optical disc recording and reproducing apparatus shown in FIG. 2. Referring to FIG. 3, the synchronization device 218 includes a time circuit 30, a logic circuit 302, a synchronization circuit 3〇3, and a temporary register/time control circuit 301 to compare target time information (TTI) and disk ^5fl (^TI), sub-generation - The U TTI indicating the start and end time of the recording process is used to indicate that the bit to be recorded on the disc is input from the interface 216. TTI is stored in the shirt two code ==

As shown in the previous section, the information of the current two = T;! indicates that the recording process starts and ends 〇 ^ 30! „ signal. , , , σ port to generate an AND circuit that indicates the start and end time of the recording process, and starts and terminates the signal of the coffee according to the one-finger process.

Bypass data DAD. When the bypass data dad is output from =, the synchronization circuit 303 stores the bypass data in the form of _eK __bits (for example, 8 or b bits) when the channel bit is used. If it is difficult to output the bypass data DAD stored in parallel. The register 304 == each element of the under-source data excitation, and outputs these bits according to the channel bit clock K string. The temporary storage II 304❸ logic circuit 305 = 3 = more positive and negative, and the one bit is output per clock cycle according to the channel bit clock U3CK. The normal recording process and the recording test process of the disc recording and reproducing apparatus will be discussed below. Fig. 4 is a green flow chart showing the normal recording process of the optical disk recording and reproducing apparatus 2 shown in Fig. 2. Referring to FIG. 4, in the normal recording mode, first, in step S41G', if the user transmits the data to be recorded through the host computer, the ATA packet interface 211 of the recording unit 21 and the buffer memory interface are stored from the host computer. The recorded data is in buffer memory 12964捣doc 220. This normal recording mode is used by the user to record the information on the disc. Thereafter, in step S420, the first encoder 213 accesses the buffer memory 220 through the buffer memory interface 212 to read the material to be recorded. Then, the brother-one encoder 213 performs the first encoding operation by adding an information frame including the header, £CC or EDC parity information to the data to be recorded, and outputting the first encoded material. At step S43, the first encoded material is stored in the SRAM memory 214. Next, in step S440, the second encoder access memory 214 reads the first encoded material, and performs a second encoding operation by merging, patching, or modulating using a DTI indicating a position on the disc, and outputs the first Two coded data. Fig. 5 is a flow chart for explaining the recording test procedure of the optical disk recording and reproducing apparatus 2 shown in Fig. 2. Referring to FIG. 5, in the recording test mode, if the user transmits the test data to be recorded through the host computer, then at step =10, the ATA packet interface 211 and the buffer memory |^ face 212 of the recording unit 210 are first stored from the host computer. The input test data to be recorded is in the buffer memory 220. The recording test mode is used by the designer or manufacturer to check that the dragon to be recorded is correctly recorded on the disc before the product is put on the market. Next, in step S520, the first encoder 213 accesses the buffer memory 22G through the buffer body 212 to read the test material to be recorded, and then does not add a parity bit or the like to encode the data. Bypass and output the test data to be recorded. Here, the test to be recorded is: 1296 gauge 7_〇. The test data is input from the main shame in the CD-DA format or the format of the CD_DA format, and is stored in the buffer memory 220 in the CD-DA format or the like, and the bypass data dad is also in the CD_DA format or A similar format is output. Here, compared with a CD-R〇M data format, the CD-DA format is a user data format in which headers, Ε(χ, edc/colocated bits, and the like are not added to the information frame of the data. in.

• Next, at step %, the synchronizing device 218 converts the bypass data DAD into a serial data. In step S540, the write strategy unit 217 generates an LD drive signal based on the tandem data of the bypass data dad in the recording test mode. The serial data is a digital signal in the NRZ or NRZI pulse format. Here, if the serial data is a digital signal of the NRZ pulse format, the data to be recorded input from the host computer and the data to be recorded read from the buffer memory 22 are all digital signals in the NRZ pulse format. Similarly, if the serial data is a digital signal of the NRZI pulse format, the data to be recorded input from the host computer and read from the buffer memory 220 are all digital signals in the NRZI pulse format. , • Write strategy unit 217 bypass data according to CD-DA format

/ 'Generates the LD drive signal. If the material to be recorded is in the CD-DA format and is not used in the writing strategy of the writing policy unit 217 without being encoded in a predetermined format, it is easy to check the recording status of the data to be recorded. That is to say, 'because the test data to be recorded is written on the disc in CD-DA format without encoding, the information written on the disc in CD-DA format can be immediately reproduced and verified without decoding operation. . Record the test mode to test whether the circuit in the record path is stable; write 8 17 2pif.doc into the correct strategy; and write the write strategy unit shown in Figure 5.

Properly generate LD crane money. That is, the LD supplied from the write unit I driver drives the LD supplied by the read unit level 7230, and based on the power of the LD drive signal, the LD emits the f-beam to form marks and spaces on the disc. The LD power must be optimally adjusted to record data on the disc. As shown in Fig. 6, during the recording process, the LD forms the LD power of the blank at the current track position by the length of the # mark and the length of the mark and the length of the mark (4) (4) after the i. Therefore, in the _ test mode, the next thorn test: write the strategy parameter 峨, to check the ld drive k time T1 爿 T4 waveform; optical power calibration job, used to calibrate = drive signal every time The power of the waveform; and a test to check if a particular pattern is properly recorded. As described above, the disc recording and reproducing apparatus 2 reads and bypasses the TMA format or the like; the data to be recorded by the SDRAM 220 is discharged. The synchronizing device 218 directly converts the D material into a string material to be encoded, and the writing strategy unit 217 uses the string data in the writer strategy. The test pattern is recorded by the LD driver 5 generated by the writer strategy unit 217. As described above, due to at least one preferred embodiment of the optical disc according to the present invention. The buffered memory sdram is used in the recording and reproducing device, so it is possible to shape the live test pattern and ensure a sufficiently long test pattern. In the conventional optical disc recording technique, since the data to be recorded is recorded on the disc after being encoded, it is difficult to check the recording state. However, depending on the type of interview to be recorded, it is transferred without coding, and x ’ checks the status of the record. Also, 'due to the use - unchanging conventional = path', the disc recording and reproducing apparatus can be used relatively low = although the invention has been disclosed in the preferred embodiment as above, the invention: any familiarity with this The craftsman, if you don't leave: the inside of the consumption, you can make some changes and refinements.
