Use the signal recorder of disc box of the present invention referring to description of drawings.Same parts among the embodiment of front are adopted same label, and omit its narration.

Among Fig. 8, detecting device 20 detects markers, pastes and is with 4 or pin 14, determines thus whether disc 2 once took out from disc box 1.To judge that disc 2 may once take out from box out-of-date when detecting device, and searcher 21 is just searched for disc 2 can not recording areas.Register 22 is used for tracer signal on disc 2, and searcher 21 is searched for defective by read write line (pickup) 23 on disc 2, and register 22 is by read write line 23 tracer signal on disc 2.

Detecting device 20 has with stickup is with 4 and pin 14 corresponding parts, can be described below these parts:

(1) with marker 4 (silver color is pasted band) relevant detection device 20:

As shown in Figure 9, the detecting device 20 of signal recorder comprises light-emitting component 24, and it upwards emits beam, and light receiving element 25, and it receives emission light.

The situation that Fig. 9 (a) expression disc 2 never took out.The light that self-emission device 24 sends is with 4 reflections by being attached to stickup on the disc box 1, receives reflected light by light receiving element 25 then, and the detecting device 20 of signal recorder identifies the luminous energy that receives and is worth greater than certain thus.Proof disc 2 never took out.

Fig. 9 (b) expression disc 2 has the situation that is removed possibility from disc box 1.Because pasting is with 4 not to be attached on the disc box 1, the insufficient light that penetrates from light-emitting component 24 is with reflection fully, be worth greater than certain so the detecting device 20 of signal recorder can not identify the luminous energy that luminous energy light receiving element 25 receives, prove that disc 2 may be removed from disc box 1.

If use opaque material in the exposure district of disc box 1, preferably the material of black or light absorbing material can expect more effectively to prevent mistake.It is as follows to imagine another detection mode:

Adopt the material (light reflective of this material not necessarily be lower than another kind of material, also can be higher than another kind of material) different for stickup with 4 surfaces with disc box housing 6 surfaces or plate washer 5 surfacing light reflective properties.Like this, the light that sends from light-emitting component 24 reflects with different sizes with disc box or barrier surface by pasting band, and whether the detecting device 20 of signal recorder can be removed the disc box by identification disc 2 by the difference of light receiving element 25 detection of reflected luminous energies.

(2) with pin 14 (marker) relevant detection device;

As shown in figure 10, the detecting device 20 of signal recorder comprises the switch 26 whether identification disc 2 may be taken out from disc box 1.

Figure 10 (a) and Figure 10 (b) expression disc 2 are never taken out from disc box 1, and switch 26 upwards moves on to the ad-hoc location that preparation detects shown in Figure 10 (b) from normal position shown in Figure 10 (a).Switch 26 contacts pin 14 and action, and detecting device 20 identifies disc and also was not removed from disc box 1 thus.

Figure 10 (c) and 10 (d) expression disc 2 have the possibility that was removed disc box 1, detecting device 20 upwards moves on to the assigned position that preparation detects shown in Figure 10 (d) from normal position shown in Figure 10 (c), switch 26 does not contact object, thereby it is failure to actuate, and detecting device 20 identifies and might once be removed from disc box 1 by disc 2 thus.

Adopt the work of the signal recorder of above-mentioned disc box to be described below:

(1) under the situation of in disc 2 Ceng Weicong disc boxes 1, taking out, since paste be with 4 and pin 14 in disc box 1, and detecting device 20 is to its detection, point out disc 2 not to be taken out from disc box 1, searcher 21 is not searched for the defect area register 22 of dish on 2 normally through read write line 23 tracer signals then.

(2) under the situation that may once from disc 1 box, be removed disc 2, paste be with 4 and pin 14 removed from disc box 1, detecting device 20 detects these situations, may once take out disc 2 from the disc box with identification.Searcher begins to search for defect area on disc 2 like this, and according to Search Results, register 22 tracer signal in the zone except that the defect area that searches on disc 2.Certainly, can forbid recording operation in this case.

Said structure makes the user can recognize dust, finger mark and other defective that disc is stained with when being taken out from disc box 1, like this, this device can be on disc tracer signal, and do not increase access to this class defect area, in other words, this structure is avoided in the defect area tracer signal equipment, or owing to defective locations not being write down and increasing access repeatedly, reduces the access time to disc 2 thus.Embodiment 4

Use the embodiment of the electronic equipment of disc box of the present invention referring to the accompanying drawing narration.The same element of narrating among the embodiment in front adopts same label, and saves its narration.

In Figure 11, display 27 (for example CRT or LCD) but show according to the Search Results of searcher 21 can not the recording capacity recording capacity or both.Display 27 can separate with signal recorder, but with its direct or indirect connection, perhaps combine with signal recorder.

Here narration has said structure and uses the working condition of the electronic equipment of this disc box.Corresponding to marker (stickup with 4 and pin 14) adopt with embodiment 3 in the detecting device 20 of spline structure.

(1) disc 2 be not removed situation from disc box 1: detecting device 20 detects to paste in the disc boxes 1 is with 4 and pin 14, points out that disc 2 never was removed, and in view of the above, but display 27 shows normal recording capacity.

(2) disc 2 situation that may from disc box 1, be removed: detecting device 20 detect paste be with 4 and pin 14 removed from the disc box, identify and might once from disc box 1, be removed by disc 2.According to this, can not posting field or posting field but judge that searcher 21 search on disc 2, data search result, but the recording capacity of display 27 demonstration discs 2, can not recording capacity or both.

The preferred embodiment of searcher 21 is described here: sensor 23 is according to Search Results recording information signal on whole disc 2 of searcher 21, this information signal comprises error correcting code and can detect mistake when information signal regenerating, can't proofread and correct when detected mistake and maybe can be corrected but during the overshoot scope, the sector that then detects mistake is just unavailable, shows that the disabled information in this sector is recorded in the assigned position place of disc 2.

Display 27 shows this information that records, and tells the write down container of user's disc 2.This operation also can be used for each magnetic track or each sector of disc 2, thus can not write down or territory, recordable sector magnetic track at the assigned position place of disc 2, be used to control recording operation to disc 2.

When disc 2 is CD, use laser log and regenerated signal usually, for top condition canned data signal in CD, acceptable laser output area should be narrow.

For example, in commercial CD-R, the best output area of laser is no more than 10% of power intermediate value, when recording information signal in this scope, error rate is no more than setting (for example, being no more than 0.00001), when regeneration one record signal the time, suppose that the laser output that is used to regenerate changes in 50%, then error rate is no more than specialized range (promptly being no more than 0.00001).

According to foregoing description as can be known, the laser output tolerance interval that is used to write down is narrow, and the tolerance interval of the laser that is used to reproduce output is wide.

In other words, in case information signal is recorded, it can reproduce safely, even a finger mark is arranged on CD or be stained with other things.On the other hand, if on disc before the recording information signal, be stained with finger mark etc., just be difficult to recording information signal.Therefore, after tracer signal on the CD, might from the disc box, take out CD, and it is packed in the reproducer with reproducing signal.

Once the CD that takes out from disc box 1 can be put into disc box 1 signal recorder tracer signal once more, and at this moment, as mentioned above, but this equipment was searched for posting field earlier before tracer signal.

Said structure allows the user to recognize owing to disc 2 being taken out defectives such as the dust that is stained with, finger mark from disc box 1, but but and the recording capacity of learning recording capacity or losing owing to defective.

According to disc box of the present invention, the user can recognize the possibility that disc wherein once was removed from the disc box, and can expect that disc contains defectiveness probably, as dust, finger mark etc.

But signal recorder tracer signal of the present invention and not increasing recording medium owing to the access of recording medium being taken out the defect area that the dust that produces, finger mark etc. cause from tray salver, signal recorder can be avoided tracer signal on the defect area of disc thus, and avoid increasing access repeatedly owing to can not writing down of defect area, shortened the access time thus.And, when recognizing that disc 2 once was removed, can forbid record.

Defectives such as the dust that electronic equipment of the present invention can be recognized the user to be stained with when taking out disc from the disc box, finger mark, but thus the user can learn disc at present recording capacity or owing to defective lose can not recording capacity.
