The test start address was sought synoptic diagram when Fig. 6 was positioned at not imprinting regional of CD shown in Figure 1 for the address of test beginning last time.

Embodiment

See also Fig. 1, it is the structural representation of CD 100.CD 100 comprises Lead-In Area 102, data field 104 and leading-out zone 106.Wherein, Lead-In Area 102 is used for the information such as initial and end address of recorded data zone 104 data, and data field 104 is used for user data, and leading-out zone 106 is used for representing the end of CD 100 data, and information-recording apparatus can be read continuously smooth.

CD 100 is at first determined the kind of CD 100 behind the information-recording apparatus of packing into, information-recording apparatus checks then according to the corresponding program that the kind of CD 100 enters corresponding disc types whether Lead-In Area 102 has write data then.If no, then the blank CD recognition method of CD 100 is finished; If write data, then information-recording apparatus need be read data.When CD 100 being carried out the imprinting test, for reducing the test duration, method for testing information recording device adopts the recognition method of blank CD, and promptly this method for testing information recording device is when test, and it is empty that the Lead-In Area 102 of CD is always, and promptly do not write data.After having adopted the recognition method of blank CD, save the time of reading data in the Lead-In Area 102, improved production efficiency.

This method for testing information recording device is divided into the test zone 108 of predetermined length with the data field 104 of CD 100, and each test zone 108 is used for the imprinting test data.The difference that the length of test zone can deduct between the low order address by the high address of CD 100 is determined.When information-recording apparatus being tested, information-recording apparatus is test zone of imprinting only at every turn.

When information-recording apparatus is tested, whether at first check in a certain test zone 108 of CD engraving data, with the start address of test zone 108 as initial inspection address.

If from checking in the predetermined length that the address begins not engraving data, to check that then the address increases in the predetermined length that the inspection address of a predetermined length after increasing begin more than or equal to CD outmost turns address or the inspection address after increasing engraving data, the inspection address that the test start address is set at after the increase reduces a predetermined length.

If from checking in the predetermined length that the address begins engraving data, will check that then the address reduces in the predetermined length that the inspection address of a predetermined length after reducing begin not engraving data, be set at inspection address after reducing with testing start address.

After determining the test start address, begin to carry out described imprinting test from the test start address.

The concrete workflow of above-mentioned method for testing information recording device sees also Fig. 2, and it is a kind of preferable method for testing information recording device schematic flow sheet.

At first, step 200 is divided into the data field 104 of CD 100 test zone 108 of predetermined length.

Step 202, establishing zone bit is 0.Zone bit is used for the redirect of control flow.

See also Fig. 3, step 204 is made as the inspection address of information-recording apparatus and tested start address A1 last time and deduct predetermined length L, checks at present that promptly the address is A2.Check that the address is the start address when test zone is carried out imprinting whether inspection, from checking that the address is to checking that the zone that the address adds the predetermined length L is a test zone.If test for the first time, promptly CD 100 is brand-new blank CD, then tests start address the last time in the step 204 and be in the data field 104 the address of close leading-out zone, i.e. location superlatively in the data field 104.

Step 206, the present inspection address A2 that sets from step 204 begins, and checks whether carrying out engraving data in the test zone.For example, getting 5 test points from inside to outside from present inspection address A2 checks.The mode of checking can setting laser power be the power that reads data in the CD 100, and judges whether imprinting of test point according to the signal that reflects.

Step 208 is writing areas for whether judging in the test zone, promptly whether to judge in the test zone engraving data according to the check result of step 206.If engraving data then enters step 218; If engraving data does not then enter step 210.Certainly, if CD 100 is to be used for for the first time test, then engraving data not enters step 210.

Step 210 is 1 for establishing zone bit, enters step 212 then.

Step 212 checks promptly that for will check that the address is made as present inspection address A2 and adds predetermined length L the address is set as the address A1 of test beginning last time.For the CD 100 that is used to test for the first time, check that the address is set as the location superlatively in the data field 104.

Step 214 checks that for judging address A1 whether more than or equal to the outmost turns address, if more than or equal to the outmost turns address, then enters step 216; If less than the outmost turns address, then return step 206.For the CD 100 that is used to test for the first time, check that the location superlatively that address A1 is set as in the data field 104 equals the outmost turns address, enters step 216.

Step 216 is promptly tested start address and is set as A2 for setting the test start address for checking that at present address A1 deducts predetermined length L.For the CD 100 that is used to test for the first time, the test start address is that the location superlatively in the data field 104 deducts predetermined length L.

After having set the test start address, step 222, information-recording apparatus begins to detect the performance of information-recording apparatus according to the imprinting result from testing the start address engraving data to CD 100.After testing a station information recording unit, CD 100 can be used to the test of next station information recording unit.

See also Fig. 4, heavy black line is partly represented engraving data among Fig. 4, i.e. the data of imprinting in first time test process.The workflow that CD 100 is used to test for the second time is as follows:

Step 202, establishing zone bit is 0.

Step 204 is made as the inspection address of information-recording apparatus and tested start address A2 last time and deduct predetermined length L, checks at present that promptly the address is A3.

Step 206, the inspection address A3 that sets from step 204 begins, and checks whether carrying out engraving data in the test zone.

Step 208 is writing areas for whether judging in the test zone, promptly whether to judge in the test zone engraving data according to the check result of step 206.If engraving data then enters step 218; If engraving data does not then enter step 210.As shown in Figure 4, when CD 100 is used to test for the second time, from checking in the test zone that address A3 begins not engraving data.

Step 210 is 1 for establishing zone bit, enters step 212 then.

Step 212 checks promptly that for will check that the address is made as present inspection address A3 and adds predetermined length L the address is set as the address A2 of test beginning last time.For the CD 100 that is used to test for the second time, check that the location superlatively that the address is set as in the data field 104 deducts predetermined length L.

Whether step 214 checks the address more than or equal to the outmost turns address for judging, for the CD 100 that is used to test for the second time, the inspection address is that the location superlatively in the data field 104 deducts predetermined length L, thereby less than the outmost turns address, returns step 206.

Step 206, the inspection address A2 that sets from step 212 begins, check whether carrying out engraving data in the test zone, as shown in Figure 4, the data of having checked in the test zone of address A2 (be in the data field 104 location superlatively deduct predetermined length L) beginning imprinting enter step 218.

Whether step 218 is 1 for the judgement symbol position.Because in the step 210, zone bit has been set as 1, thereby flow process enters step 220.

Step 220 is for setting the test start address for checking that at present address A2 deducts predetermined length L, and promptly the location superlatively in the data field 104 deducts two predetermined length L, that is the test start address is A3.

After having set the test start address, step 222, information-recording apparatus begins to detect the performance of information-recording apparatus according to the imprinting result from testing start address A3 engraving data to CD 100.Similarly, CD can carry out repeatedly test such as the 3rd, the 4th, the 5th, and its workflow repeats no more with for the second time similar.

This method of testing is divided into several test zones with CD 100, and each test zone has predetermined length L.When information-recording apparatus being tested, information-recording apparatus is test zone of imprinting only at every turn, i.e. an imprinting predetermined length L.Therefore, this method of testing does not need the whole CD of imprinting, only needs imprinting predetermined length L, reduces the test duration, has improved production efficiency.In addition, this method of testing is located at the outer ring of CD 100 with test zone, thereby information-recording apparatus imprinting test zone at a relatively high speed when test, is convenient to the performance of detecting information recording unit.And this method of testing can be set the number of times that each CD is used to test, and whenever tests once back test zone and moves to inner ring gradually from the outer ring of CD, improves the utilization factor of testing optical disk.

In addition, when CD 100 is used to a plurality of test macros, i.e. when the address of test beginning last time that stores of test macro was different from the CD address that actual test began 100 last time, method workflow shown in Figure 2 was as follows:
