At least put down in writing in the classification, maker's name, disc model etc. of CD (medium) 120 in the disc identifying information 221 of initial value table 214, record the record reproducing condition of the CD corresponding 120 in addition in the record reproducing condition 222 with these.That is, record record reproducing condition same as described above under the original state of CD 120.
The process flow diagram of the flow direction of the start up process that the CD writer 100 when proprietary CD 120 that Fig. 4 represents embodiment 1 is carried out in CD drive 110.Fig. 5 is illustrated in the CD writer 100 of this situation and the information transmission between the CD drive 110.Below, use the action of Fig. 4 and Fig. 5 Mingguang City dish CD writer 100 and CD drive 110.
Here, so-called disc identifying information is meant as described later in ID table 212, and the disc identifying information of once used CD 120 adds the state of ID table 212 to the record reproducing condition of at this moment using.
In addition, part is adjusted in 1, because the record reproducing condition of knowing the last CD 120 that uses in advance for the CD 120 that will use (for example, temperature, pollution level etc.), therefore driver controller 123 only transmits comparing vicissitudinous condition and making its optimization when using with the last time to CD drive 110 in the step 305 from the record reproducing condition of the CD 120 that will use, and CD drive 110 is sent the instruction of the record reproducing condition of transmission to record reproducing adjuster 113.
In ID table 212 under the situation of not corresponding ID (No in the step 302) with the disc identifying information of obtaining, if (Yes in the step 306) such as the maker's name corresponding with the disc identifying information of obtaining, models are arranged in initial value table 214, then driver controller 123 transmits the record reproducing condition 222 that is documented in this initial value table 214 to CD drive 110, and CD drive 110 is set the record reproducing condition of transmitting 222 (step 307, step 3001) in record reproducing memory buffer unit 112.If the condition enactment in CD drive 110 finishes (step 309), then driver controller 123 sends instruction through CD drive 110 to record reproducing condition adjuster 113, makes with the record reproducing condition of setting 222 to be that basic parameter is adjusted processing (hereinafter referred to as partly adjusting 2 by record reproducing condition adjuster 113.Part is adjusted 2 and is handled corresponding as an example with part 2 adjustment of the present invention) (step 308, step 311).
Here, so-called have the disc identifying information in initial value table 214, is meant the state that exists in initial value table 214 with corresponding to disc identifying information 221 such as the maker's name of the CD 120 that will use, model and record reproducing condition 222.
In addition, so-called record reproducing condition is meant 110 pairs of CD 120 recorded informations of CD drive or the condition of work of the CD drive 110 during with the information playback of CD 120 record.The servo condition of the various servo action when the record reproducing condition comprises the impulsive condition of the laser of CD 120 irradiation, decision record reproducing at least and handle in the replay signal treatment conditions that replay signal uses one.In addition, impulsive condition comprises the performance number of the laser that when for example writing down CD is shone.Perhaps, impulsive condition also can be included in the lasing condition that forms mark (least unit of information) usefulness on the CD.Fig. 3 represents to write down or relevant parameter such as pulse width of playback time and power laser, laser, servocontrol, but is not limited thereto.
In addition, adjust in 2, use the record reproducing condition of the CD 120 that from initial value table 214, obtains, the CD 120 that will use is adjusted processing make it become optimal conditions in part.Thereby driver controller 123 sends instruction to CD drive 110 in step 308, makes it carry out such adjustment and handles.
On the other hand, under the situation of not corresponding disc information 220 (No in the step 306) with the disc identifying information of obtaining, 123 pairs of CD drive 110 of driver controller are sent instruction (step 311), making it is that prerequisite is adjusted processing (below, be called full adjustment) with the basic parameter that does not match with this CD 120.In full the adjustment, CD 120 all record reproducing conditions are optimized.
When Fig. 6 and Fig. 7 represent that CD 120 is installed in the CD drive 110, the action flow chart that carries out according to the instruction of CD writer 100 of CD drive 110.
At first, key diagram 6.
When CD drive 110 is received the instruction that obtains the disc identifying information from CD writer 100 (step 297), starter controller 111 carries out the disc identification (step 400) of CD 120, the disc identifying information of obtaining to CD writer 100 transmissions (step 300).
Follow Fig. 7 is described.
When CD writer 100 is received the instruction of adjusting processing (Fig. 5, step 311), the content of CD drive 110 storage instruction in record reproducing memory buffer unit 112.And the record reproducing adjuster 113 of CD drive 110 is resolved the content (step 500) of the instruction of receiving.The content of instruction be with record reproducing condition memory buffer unit 112 in the record reproducing condition 222 of storage be that basic parameter is adjusted ([part adjusts 1] in the step 500 or [partly adjusting 2]) under the situation of processing, record reproducing condition adjuster 113 is obtained the record reproducing condition 222 (step 501 or step 502) of storage in the record reproducing condition memory buffer unit 112, is that basic parameter is adjusted processing (step 503 or step 504) with this record reproducing condition 222.On the other hand, in the content of instruction is to be that prerequisite is adjusted under the situation of processing ([the full adjustment] in the step 500) with the basic parameter that does not match with this CD 120, record reproducing condition adjuster 113 is with no basic parameter, or the basic parameter that for example has as general condition in the service recorder playback condition memory buffer unit 112, come and adjust processing (step 505).
Under this situation, at CD 120 for installation, during the general record reproducing condition that can utilize that CD drive 110 has, then adjust processing according to this record playback condition, but under the situation of the CD 120 that can not use general record reproducing condition or under the situation of the adjustment of carrying out according to general record reproducing condition processing failure, repeat to adjust and handle, up to finding best record reproducing condition.
If when adjusting order fulfillment (Fig. 5, step 312), then the driver controller 123 of CD writer 100 is obtained to CD drive 110 requests and is adjusted result's (Fig. 5, step 313).Then, receive adjustment result's (Fig. 5, step 314) from CD drive 110, driver controller 123 upgrades disc informations (step 506).Promptly, even adjust to handle adjust entirely, part adjust 1 and part adjust any adjustment in 2, driver controller 123 is obtained from CD drive 110 and has been carried out the record reproducing condition of optimizing (Fig. 5, step 314) to adjusting the result who handles, and adds in the ID table 212 with the disc identifying information.
Like this,, this record reproducing condition 222 is used for adjusting processing, just can shortens the time of handling of adjusting by retrieving disc information table 200 according to the disc identifying information, and, can improve and adjust the processing possibility of success.Its result can shorten the starting time.
Particularly, afterwards, do not eject CD 120 and shift to once more under the record or the situation of playback mode once being in waiting status (for example halted state), from the disc information table 200 of disc information memory buffer unit 102, obtain and use the playback of the resulting records as a result condition of handling of adjusting immediately, before the record reproducing processing, do not need spended time.In addition, optical discs in general driver 110 is stopped power supply for power saving in waiting status, but because only otherwise the power supply that stops CD writer 100 main bodys does not just stop, even, also can keep the record reproducing condition of storing therefore in waiting status to the power supply of disc information memory buffer unit 102.Its result, do not eject CD 120 and from waiting status shift to can video replay state the time, even without stored record playback condition, record reproducing controller 114 also can use necessary record reproducing condition immediately at opening entry playback time once more in the record reproducing condition memory buffer unit 112 of CD drive 110.
In addition, by record reproducing condition 222 being stored in the disc information memory buffer unit 102 of CD writer 100, can store the record reproducing condition 222 relevant, can shorten and adjust the processing time and improve to adjust and handle possibility of success with a plurality of CD 120.In addition, owing in the record reproducing condition memory buffer unit 112 of CD drive 110, needn't store the record reproducing condition relevant with a plurality of CD 120, so can suppress the capacity of storer.That is, can use the universal product of PC etc. as CD drive 110.
Also have, in the present embodiment, be in disc information memory buffer unit 102 storage complete adjust, part adjust 1 and part adjust 2 adjustment any one result in handling, but only also can consider to adjust or part is adjusted under 2 the situation these results of storage in disc information memory buffer unit 102 complete.
