Description

Information recording method, information recording and reproducing apparatus and information recording medium

In recent years, with the increase in the capacity of information devices such as computers, optical discs have attracted attention as recording media.

Hereinafter, a conventional optical disc cartridge will be described with reference to the drawings. FIG. 14 is a plan view of a conventional optical disc cartridge.

As shown in FIG. 14, the optical disc 201 is a recording medium capable of recording and reproducing information, and the case 202 houses the optical disc 201 therein and contaminates the optical disc 201 with dust, fingerprints, and the like. It is a case to protect from. The opening window 203 is a window provided on the case 202 to enable recording and reproducing of information when the optical disc 201 is mounted on the recording / reproducing apparatus. The opening window 203 is normally closed by a sliding shutter. Here, the case in which the optical disc is stored is called a cartridge 204.

In general, an optical disk capable of recording and reproducing, when fingerprints or dirt adheres to the surface, the power irradiated from the semiconductor laser onto the recording surface becomes less than an appropriate value, and the reliability of recording is significantly reduced.

In order to avoid such a decrease in reliability, the recording / reproducing type optical disc 201 described in FIG. 14, such as an ISO standard data file or an MD disc, is of a case storage type as described above.

Next, for example, a case of an optical disk (not shown) of a reproduction-only type such as a CD disk or an LD disk will be described.

That is, since the recording-only optical disc is not recorded by the user, unlike the case described in FIG. In this reproducing apparatus, only the optical disc which is not a case storage type can be reproduced.

For this reason, since the recording / reproducing type optical disc 201 shown in FIG. 14 is housed in the case 202, there is a drawback that the reproducing apparatus for reproducing an optical disc of reproduction type cannot be reproduced.

To solve this drawback, a cartridge 214 having a configuration as shown in Figs. 15 (a) and (b) is designed. FIG. 15A is a plan view of a state where the optical disc 201 is accommodated in the case 212, and FIG. 15B is a plan view of a state where the optical disc 201 is drawn out from the case 212. FIG.

That is, as shown in Figs. 15A and 15B, the case 212 is a case for accommodating the optical disc 201, and has an opening window 203 used for recording and reproducing. The shutter 213 is installed. The opening / closing door 211 is rotatably attached to the opening provided in the end surface of the case 212, and is a door for taking out the optical disc 201 from the case 212.

In the case of the cartridge 214 having such a configuration, since the opening and closing door 211 can be opened and only the optical disc 201 can be taken out, the cartridge 214 can also be mounted to a device for reproduction only.

Accordingly, the case-type recording / reproducing type optical disc 201 can be reproduced by using a reproducing apparatus capable of reproducing an optical disc of a reproduction type only.

On the other hand, the jukebox 223 is stored in the stocker 221 in a state where a plurality of recording and reproducing type optical discs are uncased, and the recording and reproducing section 222 executes recording and reproducing for each optical disc 201. A recording and reproducing system called) is known (see FIG. 16).

In the case of the juke box 223, since the optical disc 201 is already stored in the stocker 221 from the time of shipment from the manufacturer, the optical disc 201 is not directly contacted by a user's hand or the like. For this reason, fingerprints, wounds, and the like are hardly adhered to the optical disk 203 surface.

In the juke box 223, the user extracts the optical disc 201 separately from the cartridge 214 as shown in FIG. 15, apart from the optical disc 201 already stored in the stocker 221. Can be stored and recorded and played back.

In this manner, the case-type recording / reproducing type optical disc shown in FIG. 15 can be used for the juke box 223 having the above-described configuration.

However, the conventional recording and reproducing type optical discs, which can be reproduced using a reproducing apparatus capable of reproducing only an optical disc of a reproduction-only type, have the following problems.

That is, once the optical disk 201 is pulled out of the case 212, fingerprints, dirt or wounds are attached to the optical disk surface. Therefore, the problem is that the reliability of the data recorded by the fingerprint or the like attached to the surface of the optical disc is remarkably lowered when it is put in the case 212 and mounted on the recording / reproducing apparatus.

When the conventional recording / reproducing type optical disc is used in the juke box 223 described above, the optical disc stored in the stocker 221 via the user's hand and the optical disc stored in the stocker 221 from the time of shipment from the manufacturer, The former has the problem that dirt may adhere, and the latter does not have such a problem that the level of reliability of the recorded data differs.

The present invention relates to an information recording method, an information recording apparatus and an information recording medium.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing a schematic relationship between an information recording method, an information recording apparatus and an information recording medium of one embodiment according to the present invention. An outline of this embodiment will be described with reference to FIG.

(1) In FIG. 1, the optical disc 1 as a medium of the present invention is a medium capable of recording and reproducing information, and is housed in a case 2. A part of the case 2 is provided with an opening / closing door (see FIG. 3) for drawing out the optical disc 1, and an identification section 3 for recording history information of whether the optical disc 1 has been drawn out. Is installed. These are collectively referred to as a cartridge 4. The detailed configuration and the like of the cartridge 4 will be described later.

The recording and reproducing apparatus 5 as the information recording apparatus of the present invention is an apparatus for recording and reproducing the case accommodating optical disc 1, and details of the configuration and the like will be described later. The reproduction exclusive device 6 is a device for reproducing an optical disc in a caseless state.

The cartridge 4a shows an empty state in which the optical disc 1 is drawn out from the cartridge 4, and the cartridge 4b shows a state in which the optical disc 1 is drawn out again.

In this configuration, the entire flow will be described using FIG.

That is, as shown by arrow A in FIG. 1, no scratches or dirt are attached to the optical disc 1 while the user is performing normal recording using the cartridge 4. In the state indicated by such an arrow A, the identification part 3 maintains the initial shape like the factory shipment. However, when the cartridge 4 is used in the reproducing device 6, the optical disc 1 is first taken out from the case 2 (see arrow B shown in FIG. 1), and the reproducing device 6 is used. (See arrow C shown in FIG. 1). When the user pulls out the optical disc 1 from the case 2, the opening and closing door does not open unless the projection of the identification part 3 is removed. Remains in (3). Therefore, as shown by the arrow D, even when the optical disc 1 is returned to the case 2, the history information indicating that the optical disc 1 is drawn out to the identification unit 3 is different from the original cartridge 4 in the cartridge 4b. Attached.

Therefore, in the present embodiment, when such a cartridge 4b is mounted in the recording / reproducing apparatus 5, when recording, the reliability of the recorded information can be further improved by detecting the history information attached to the identification section 3. That is, as an example, for example, the recording and reproducing apparatus of the present embodiment displays the contents when the identification section 3 detects that the optical disc 1 has been pulled out of the case 2. In accordance with an instruction from the user, it is verified whether or not the currently recorded information has been recorded correctly (hereinafter, this verification is also called verify), and if it is determined that the information has not been recorded correctly, the same information is recorded again.

(2) The above is a description of the outline of the present embodiment, and will be described in more detail.

2 to 5 are block diagrams of the cartridge 4 used in the present embodiment, and the structure of the cartridge 4 will be described with reference to FIGS. 2 to 5.

2 is an external perspective view of the cartridge 4. The same parts as those described with reference to FIG. 1 are given the same reference numerals and the description thereof will be omitted.

In FIG. 2, the opening window 10 is a window provided on the case 2 to enable recording and reproducing of information when the optical disc 1 is mounted on the information recording and reproducing apparatus 5. This opening window 10 is normally closed by the sliding shutter 11 (refer FIG. 3). 2 shows a state in which the shutter 11 is removed for convenience of understanding the structure of the opening window 10. The opening part 17 is provided in the end surface 16 of the case 2, and is for taking out the optical disc 1 from the case 2. As shown in FIG. The opening / closing door 14 is rotatably provided by the hinge part 15 so that the opening part 17 may be blocked. The engagement hole 12 is a slit provided in the end surface 18 of a case, and engages with the clamp part 19 (refer FIG. 4) provided in the opening / closing door 14 mentioned later. In addition, the case of the present invention includes a case 2 and the opening and closing door 14 and the like.

FIG. 2 shows a state in which the opening / closing door 14 is blocking the opening 17, and FIG. 3 shows a state in which the opening / closing door 14 is open. 4 is a perspective view of the opening / closing door 14.

As shown in FIG. 4, the opening / closing door 14 is a substantially rectangular plate-shaped member, the front side of the figure corresponds to the end face 16 of the case 2, and has a planar shape. The inner side of the figure faces the optical disc 1 when the opening / closing door 14 is closed, and its side surface is curved to conform to the outer shape of the optical disc 1. The thickness of the opening / closing door 14 corresponds to the height of the opening 17 (part corresponding to the thickness direction of the case 2). The clamp part 19 is a plate-like protrusion which has spring property provided in the cross-sectional side of the short direction of the opening / closing door 14. When the opening and closing door 14 is in the state which the opening part 17 is blocking the clamp part 19, the front end part engages with the engagement hole 12 of the case 2 side, and the clamp part from the engagement hole 12 is carried out. When the distal end of 19 is pushed inward, the engagement state is released. The identification part 3 is for recording the history information of whether the optical disc 1 has been pulled out from the case 2, and two pieces are provided in total at the both ends of the opening-closing door 14 in the longitudinal direction.

5 is an enlarged perspective cross-sectional view of the identification section 3. As shown in FIG. 5, the identification part 3 has the identification hole 3a provided in the opening-and-closing door 14, and the identification body which penetrates the hole, maintaining the predetermined space | interval at the center of the identification hole 3a. (3b) and the support part 3c for partially tying the identification body 3 and the inner wall of the identification hole 3a. As shown in Fig. 5, the identifier 3b is substantially cylindrical in shape, and a positive groove 3d is formed in the upper section of the figure so that the tip of the positive driver enters. In addition, the case 2 has the closing door 14 closed, and the confirmation hole 13 (refer to FIG. 2) which allows the positive driver to be inserted in the position corresponding to this identification part 3 opposes on both sides. A total of four are installed in each of two locations.

The operation when the optical disc 1 enters and exits from the case 2 in the above configuration will be described with reference to FIGS. 1 to 5.

The overall flow when the user uses the cartridge 4 is as described in FIG. 1, and here the place described with the arrows B and D in FIG. 1 with respect to the identification section 3 is described. The explanation will be centered.

(a) First, in order to withdraw the optical disc 1 from the case 2, the user inserts a driver from the confirmation hole 13 shown in FIG. 2, and the tip portion thereof in the groove 3d (see FIG. 5). Tighten the screwdriver slightly by tightening. At this time, the support part 3c is cut | disconnected by the rotational force, the identification body 3b is isolate | separated from the identification part 3, and falls out of the case 2 from the confirmation hole 13 provided in the opposite side to the case 2.

(b) The same operation is performed also on the other identification part 3.

(c) Next, insert a negative driver from the engaging hole 12 of the case 2, and hold the handle 14a at the center of the opening / closing door 14 while pressing inward on the leading end of the clamp portion 19. Pull on. This opens and closes the door 14 as shown in FIG.

(d) The optical disc 1 is slid from the case 2 by sliding the door 14 completely open.

As a result, history information indicating that the optical disc 1 is drawn out by the identification 3b of the identification unit 3 removed is left in the case 2 as a trace.

Accordingly, even when the optical disc 1 is returned to the original case 2 as described with reference to the arrow D in FIG. 1, the identification unit 3 retains the history information indicating that the optical disc 1 is drawn out. This history information is detected by the recording / reproducing apparatus 5 described later and used for recording.

(3) In the above, after the description of the cartridge 4 is finished, the configuration of the recording / reproducing apparatus 5 will be described with reference to FIG. 6 is a block diagram showing the configuration of the recording / reproducing apparatus 5. As shown in FIG.

In Fig. 6, the history determining means 31 detects the state of the identification portion 3 of the cartridge 4 by means of detection means described later to determine whether the optical disc 1 has been withdrawn from the case 2 or not. It is a means for determination and means for outputting the determination result to the display part 32 etc. which are mentioned later. The display unit 32 obtains the determination result from the history determination means 31, and displays a message for confirming the user's intention of whether or not to perform the verification described later according to the content, the content after the verification, and the like. will be. The selection indicating means 33 is means for receiving an instruction by the user of whether or not to perform verification and outputting the instruction content to the verification means 34. The verification means 34 is means for verifying that the information recorded by the recording means 35 described later is correct according to the instruction from the selection indicating means 33, and outputting the verification result. The verification means 34 has an error correction circuit and the like. The recording means 35 is a means for rewriting in accordance with the verification result from the verification means 34 in addition to performing normal recording. The end means 36 is a means for terminating the recording on the assumption that the recording is completed when a verification result indicating that the information to be verified is correctly recorded from the verification means 34 is obtained.

In addition, as the contents of the verification result indicating that the information to be verified is correctly recorded, compared to the information to be recorded, if the error is not included at all, and the error is within the correctable range, Or, it is included outside the correctable range, but the number of the error is within a predetermined range.

Next, the structure of the detection means in the said history determination means 31 is demonstrated using FIG. 7 (a), (b). That is, the light emitting element 41a and the light receiving element 41b are means for detecting the presence or absence of the identifier 3b, and at a position corresponding to the identifier 3b of the cartridge 4 mounted on the recording / reproducing apparatus 5; In addition, the case 2 is installed so as to face each other. FIG. 7 (a) shows a state where the identifier 3b is present, and FIG. 7 (b) shows a state where the identifier 3b is absent. Only in the case shown in FIG. 7 (b), the light receiving element 41b is configured to receive light from the light emitting element 41a.

In the above configuration, the operation of the recording / reproducing apparatus 5 according to the present embodiment will now be described with reference to the drawings, and the information recording method as the present embodiment will be described simultaneously. 8 is a flowchart for explaining the operation and information recording method for the recording and reproducing apparatus of this embodiment.

Hereinafter, with reference to FIG. 8, the case of arrow E described in FIG. 1 will be described.

Step 1 (ST1): In the identification section 3 of the cartridge 4b shown in FIG. 1, history information indicating that the optical disc 1 has been once drawn out is left as described above. A cartridge 4b having such history information is mounted in the recording / reproducing apparatus 5 to instruct the recording operation.

Step 2 (ST2): If there is an instruction for a recording operation, the history determining means 31 detects the presence or absence of the identifier 3b by the light receiving element 41a and the light emitting element 41b (see also the seventh (b)). do. Here, since the identification body 3b has already been removed, it is determined that the optical disc 1 has been once drawn out from the case 2, and the flow proceeds to step 3.

When it is determined that the identifier 3a is present as a result of detecting the presence or absence of the identifier 3b, an instruction is issued from the history determining means 31 to the normal recording means to the recording means 35. Proceed to step 4.

Step 3 (ST3): A message is displayed on the display unit 32 to confirm whether or not to verify or verify the information to be recorded by the user from now on. The user inputs an indication of whether or not to verify this display content by the selection indicating means 33. When an instruction to perform verification is input from the user, an instruction to execute recording on the premise of verification is issued from the verification means 34 to the recording means 35, and the flow proceeds to step 5. If an instruction is input from the user not to perform verification, an instruction indicating that only normal recording is to be performed is issued from the verification means 34 to the recording means 35 and proceeds to step 4.

As described above, since the user can select whether or not to verify, the disadvantage of reducing the recording speed when performing verification uniformly can be reduced.

Step 4 (ST4): This is the normal recording process performed by the recording means 35, and when the recording is completed, the operation is completed without verification and waits for the next instruction from the user.

Step 5 (ST5): The recording means 35 records the information desired by the user, and then proceeds to step 6.

Step 6 (ST6): The verification means 34 verifies the information recorded in step 5.

That is, (1) The currently recorded area is reproduced. (2) At the same time, operate the error correction circuit and check the number of errors generated.

Step 7 (ST 7): The verification means 34 determines whether the number of errors checked in step 6 is within an error correctable range. If the error is within the correctable range (Verify OK), the message is notified to the terminating means 36, and the recording operation is terminated (step 10). If the error correction range is exceeded, the process proceeds to step 8 again.

Step 8 (ST8): The verification means 34 checks the number of uncorrectable errors and determines whether the number is within a predetermined predetermined range. As a result, if it is within the predetermined range, the message is sent to the terminating means 36, and the recording operation is terminated (step 10). If the result exceeds the predetermined range, the process proceeds to step 9.

Step 9 (ST9): From the verification means 34, the recording means 35 again gives an instruction to rewrite in the same area or a new area, and the recording means 35 performs rewriting. After rewriting, the process returns to step 6 again and repeats the above process.

Step 10 (ST10): The recording operation is terminated by the terminating means 36, and the effect thereof is displayed on the display portion 32. FIG.

In addition, a series of operations (steps 5 to 10) for verifying it after recording are collectively referred to as write verification (write verification).

According to the present embodiment as described above, the reliability of the recorded information can be further improved.

Next, another embodiment will be described with reference to the drawings.

The stocker 63 incorporates a plurality of optical disks in a caseless state, and is used in recording and reproducing by the recording and reproducing apparatus 62. FIG. The optical disk 64 built into the stocker 63 from the beginning is an optical disk which is stored in the stocker 63 already at the time of shipment from the manufacturer without the user directly contacting it by hand. On the other hand, the optical disk 52 in the stocker 63 is an optical disk which the user withdraws from the case 51 by hand, and is later put into the stocker 63. In FIG. 9, for convenience of explanation of the optical disc 52 and the optical disc 64, dots are shown only on the optical disc 52 for clarity.

An important point here is that the optical discs 52 and 64 as the information recording medium of this embodiment contained in these stockers 63 are provided with an optical disc management area 53 for writing management information. This disk management area 53 will be described in more detail with reference to FIG. Fig. 10 is a partially enlarged schematic diagram showing the physical layout of the optical disc of this embodiment.

That is, as shown in FIG. 10, on each sector of the optical disc, the lead-in area 71, the disc management area 53, the data area 72, and the lead-out area from the inner circumference side to the outer circumference side of the optical disc. 73 is installed. The disk management area 53 and the data area 72 correspond to the user area 74.

In the disc management area 53 of the optical disc 52, "1" is written as data indicating that there has been an outside of the stocker, and the disc management area 53 of the optical disc 64 has been outside the stocker. "0" is written as data indicating that there is no presence. The recording of data into the disc management area 53 will be described later.

Examples of optical discs that have been external to the stocker include (1) the case of so-called case storage type optical discs, which are to be used or currently being used in devices other than the juke box 61, such as ordinary recording and reproducing apparatuses, and (2) Originally, a case of a recording / reproducing type optical disc which was built in the stocker 63 of the juke box 61 but was once drawn out to the outside and returned to the stocker 63, which did not enter the case, can be considered. have.

Here, for example, in the juke box 61, when the optical disk comes and goes between the stocker 63 and the recording / reproducing device 62, the human hand does not touch the human hand, and thus is actually drawn out of the stocker. I cannot think that I did it. Therefore, such an optical disc does not correspond to an optical disc that has been outside the stocker.

Next, the configuration of the recording / reproducing apparatus 62 of this embodiment will be described with reference to FIG.

The recording and reproducing apparatus 62 is almost the same as the configuration of the recording and reproducing apparatus 5 described in FIG. 6 except for the configuration of the history determining means 81. Therefore, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In FIG. 11, the disc management area reproducing unit 81a reproduces data written in the disc management area 53 of the optical disc 52 or the optical disc 64 set in the recording / reproducing apparatus 62 from the stocker 63. In FIG. will be. The disc history information determining unit 81b is a means for obtaining data reproduced by the disc management area reproducing unit 81a and determining whether the optical disc is outside the stocker, and displaying the determination result on the display unit 32. ) And so on. In the present embodiment, the disc management area reproducing unit 81a and the disc history information determining unit 81b are collectively referred to as the history determining unit 81.

In the above configuration, the operation of the juke box 61 in the present embodiment will now be described with reference to the drawings. 12 is a flowchart for explaining the operation of the jukebox 61 of the present embodiment.

Step 101 (ST101): When one optical disc is selected from the stocker 63 shown in FIG. 9 in accordance with the disc selection instruction from the user and automatically set in the recording / reproducing apparatus 62, the disc management area reproducing unit ( The disc management area 53 is reproduced by 81a).

Step 102 (ST102): The disc history information determination unit 81b obtains the reproduction result and checks whether or not the data written in the disc management area 53 is "1". If it is determined as "1", the selected optical disc is regarded as an optical disc that has been outside the stocker, and the flow advances to step 103.

If it is determined as "0", the selected optical disk is regarded as an optical disk which has never been outside the stocker, and is normally used for the recording means 35 from the disk history information determining portion 81b, that is, the history determining means 81. Proceed to the record to proceed to step 104.

Step 103 (ST103): A message is displayed on the display unit 32 to confirm whether or not to verify the information to be recorded by the user from now on. The user inputs an indication of whether or not to view this display and verify by the selection instructing means 33. If an instruction to verify from the user is inputted, the verification means 34 outputs an instruction to execute recording verification on the premise of verification to the recording means 35, and proceeds to step 105 (ST105). If an instruction indicating that verification is not made by the user is entered, an instruction to perform only normal recording is issued from the verification means 34 to the recording means 35 and proceeds to step 104 (ST104). In addition, since the operation of recording verification in step 105 is the same as that in steps 5 to 10 described in FIG. 8, the description thereof is omitted.

As described above, since the user can select whether or not to verify, the disadvantage of reducing the recording speed in the case of uniform verification can be reduced.

Next, recording of data of "1" or "0" into the disc management area 53 will be described with reference to FIG.

It is also assumed that "0" is recorded in the disc management area 53 of the optical disc accommodated in the juke box at the time of factory shipment. The recording / reproducing apparatus for recording data into the disc management area 53 is a device different from the juke box 61.

However, in the recording and reproducing apparatus, the optical disc which needs to record "1" in the disc management area will be described again before the operation description. In other words, it is unpredictable whether or not the optical disc outside the stocker 63 will enter the stocker 63 in the future. Therefore, in the recording / reproducing optical disc, it is necessary to write "1" in the disc management area 53 as long as it is in a state where it can be reached by the user, regardless of whether or not the so-called case is stored.

The recording and reproducing apparatus referred to here uses the optical disc 114 of the recording / reproducing type described in FIG. 15 except for the fact that " 1 " can be recorded in the disc management area 53 in this way. It is almost the same structure as the recording / reproducing apparatus.

However, as shown in Fig. 13, when an optical disc is mounted in this recording / reproducing apparatus and there is a recording instruction from the user, a confirmation message indicating whether or not a format must be displayed is displayed on the predetermined display means (step 201 (ST201). )). The user who saw this message inputs, by the format selection instruction means, an instruction indicating that format processing is required for the optical disc just purchased. If an instruction indicating that format is required is obtained, " 1 " is written in the disc management area 53 by the management information recording means, and at the same time, the format is executed (step 202 (ST202)). After that, the normal recording operation is executed (step 203 (ST203)). If the format processing has already been completed, an instruction indicating that format is not required by the user is input by the format selection instruction means. If an instruction indicating that formatting is not required is obtained, the recording means performs a normal recording operation (step 203). The above operation may be performed even when the optical disc to be mounted is not stored in a so-called case.

Alternatively, the following configuration may be used as another example of recording "1" or "0" into the disc management area 53.

In other words, if the distribution path of the optical disc is clearly distinguished from the jukebox only and other ways, "0" may be recorded on the jukebox-only optical disc and "1" on the other optical disc at the factory shipment stage.

According to the present embodiment, the recording verification can be performed according to the history information of the plurality of disks stored in the juke box, so that the reliability of the recorded information can be further improved, and the reliability difference between the optical disks can be reduced. Can be.

However, in the above embodiment, the optical disc in which "1" is to be recorded in the disc management area has been described as follows.

In other words, it is unpredictable whether the optical disc outside the stocker 63 will be stored in the stocker 63 in the future. Therefore, in the recording / reproducing optical disc, it is necessary to write “1” in the disc management area 53 as long as it is in a state where it can be touched by the user, regardless of whether it is a case storage type or a storage type. .

On the other hand, here, an optical disc in which " 1 " needs to be recorded in the disc management area will be described on the assumption that it is different from the case described above.

In other words, in order to record the optical disk 64 from the outside of the stocker 63, it cannot be recorded unless it is a case storage type, that is, it cannot be recorded in a state without a case.

More specifically, for example, in order for a user to record an optical disk 64 that is not a case storage type from the outside of the stocker 63, a user purchases a disk case sold separately and stores the optical disk 64 in the disk case. Can not be recorded.

When recording in this way, "1" is always recorded in the disc management area 53.

Thus, for example, whether or not to write "1" or "0" in the disc management area 53 when the optical disc is formatted is determined whether the optical disc is currently in a case at the time the write operation is performed. It depends on whether or not. In other words, the optical disc which needs to record "1" in the disc management area is the optical disc currently in the case. Incidentally, when disc management information is written during optical disc production, it will be described later.

Specifically, for example, in the recording / reproducing apparatus, at the time of formatting, the judging means judges whether the optical disc is currently in the case, and judges that the disc is in the case. 1 ”is written.

However, the case where the disc management information is written during disc production will be briefly described. In this case, for example, (1) the premise that the distribution paths of the optical disc without a case used as the juke box and the optical disc used in the case are clearly distinguished, and (2) the juke box. An optical disc without a case inside is not used outside of the stocker, but an optical disc used in the case can be stored out of the case and stored in the stocker. Is written. In other words, "0" is written into the disc to be used without a case as the disc management information, and "1" is written into the optical disc to be used in a case where the disc can be taken out.

The recording / reproducing apparatus or juke box in which the optical disk on which the management information described above is written is used has the same basic operations as those described above with reference to Figs. In other words, if "1" is specified in the management information, the operation of recording verification is enabled. Therefore, even in such a case, the same effects as in the above-described embodiment can be obtained.

In the above embodiment, the case where the instruction from the user is accepted by the selection instructing means has been described. However, the present invention is not limited to this. For example, the verification may be always performed in accordance with the determination result of the history determining means. .

In the above embodiment, when the number of checked errors exceeds the error correctable range as a result of the determination by the verification means, the process proceeds to step 8 again and the case where the above operation is performed has been described. However, the present invention is not limited thereto. For example, it may be forcibly terminated without proceeding to Step 8 and without performing a rewrite operation. In this case, of course, a message or the like indicating that an error is included in the currently recorded information may be displayed on the display unit.

In the above embodiment, the rewrite by the verification means has been described in the case of rewriting in the same area of the optical disc. However, the present invention is not limited to this, and may be configured to rewrite in another area, for example.

In the above embodiment, the case where rewriting is always performed when the number of uncorrectable errors exceeds a predetermined range has been described, but the present invention is not limited to this, and may be forcibly terminated without rewriting, for example. In this case, it goes without saying that a message or the like indicating that an error is included in the currently recorded information may be displayed on the display unit.

In the above embodiment, the number of non-correctable errors has been described on the premise that there is one reference value in a predetermined range. However, the present invention is not limited thereto, and for example, a plurality of reference values re-determined within a predetermined range are exceeded. Depending on the number of uncorrectable errors beyond the above-mentioned range, the processing may be performed by (1) forced termination, (2) rewriting to another area, or (3) rewriting to the same area. It goes without saying that it may be configured to classify.

As can be seen from the above description, this embodiment has the advantage that the reliability of the recorded data can be further improved as compared with the prior art.

Next, the Example of this invention is described using drawing.

The present invention is an invention in the case where a special optical disc that can be recorded even when taken out from a case by subjecting the surface of the optical disc to a special processing or the like is also subjected to recording and reproduction.

In the present invention, when an optical disc whose recording is undesired when it is taken out from the case becomes a target, the above-described history determination is not made, that is, the history of the withdrawal from the case is not examined and the recording mode is not changed. It is forbidden to record or conditional recording such as inspection after defect inspection or inspection after recording.

The present invention also covers a case where the optical disk as shown in FIG. 14 is not drawn out.

[First Embodiment]

Fig. 17 is a diagram of an optical disc for recording and reproducing, which is an information carrier for recording and reproducing in one embodiment of the present invention. In Fig. 17, reference numeral 101 denotes a first optical disc which enables conditional recording such as recording prohibited or recording after defect detection and inspection after recording in the single use state. The first optical disc has a spiral type continuous information track 102 for recording and reproducing information. At the head of the information track 102, a first optical disc identification code 103 is formed, which functions as a medium identification information part. have.

104 is a second optical disk capable of normal recording even in a state where it is taken out from the case, that is, in a single use state, and has the same information track 105 as the first optical disk 101. The second optical disc identification code 106, which functions as a medium identification information section, is formed at the head. A second optical disk capable of normal recording even when passing through a state drawn out from such a case is, for example, by performing an antistatic coating film on the surface of the disk or performing a surface treatment such that fingerprints are difficult to adhere. Can be realized.

18 is a perspective view of one embodiment of a first case for housing an optical disc. In FIG. 18, reference numeral 107 denotes a first case, and the first optical disc 101 or the second optical disc 104 is housed therein, and the optical disc cannot be taken out. 108 is an optical pickup 117 to be described later, an opening for inserting the disk motor 116, 109 is a shutter for opening and closing the opening 108, 109a is an opener recess formed in the shutter 109, 110 is an optical disk device described later The positioning hole 111 for engaging the case 107 in a predetermined position in engagement with the positioning pin 18a is a case identification hole which functions as a case identification information part, and is closed in this first case 107. In addition, the case detection switch 120 of the optical disc apparatus mentioned later comes in contact with the part of the positioning hole 110 of the case surface, and this part has the function of the case presence information part of this invention.

FIG. 19 is a perspective view of one embodiment of a second case for storing the optical disc of the present invention, FIG. 19 (a) shows a state where the optical disc is stored, and FIG. 19 (b) shows a state where the optical disc is taken out. In Fig. 19, the same reference numerals as those in Fig. 18 denote the same members, and a description thereof will be omitted. In FIG. 19, reference numeral 112 denotes a second case, and the opening and closing cover 113 for allowing the optical disk to be pulled out or stored in the rear portion of the case is rotatable freely, and the optical disk can be attached and detached. 114 is a case identification hole for the second case 112 at the same position as the case identification hole 111 of the first case 107 and is a through hole. In the vicinity of the positioning hole 110 on the case surface, the case detecting switch 120 of the optical disk device described later is brought into contact with the case, and this portion has a function of the case presence information section of the present invention.

When the first and second optical discs and the first and second cases are combined, there are six types, and there are recording modes corresponding to those six types.

Table 1 shows an example of the combination, and as shown in Table 1, the optical disc apparatus switches the appropriate recording method according to the combination.

In Table 1, the second optical disk 104 can be recorded normally with or without a case. The use conditions of the first optical disc 101 differ depending on the presence or absence of a case and the type of the case. The first optical disc 101 accommodated in the first case 107 can be recorded normally. This is because the optical disk is not drawn out from the case, and dust and fingerprints are very hard to adhere to, and this corresponds to the general method of using the conventional optical disk.

The first optical disc 101 housed in the second case 112 enables recording after prohibition of recording or defect detection. This is because, in the case of the second case, the optical disk 101 is taken out in the past, and attachment of a fingerprint or the like is considered. Therefore, once the information track is checked whether there is a defect, the information track is recorded on the defect-free information track to increase the reliability of the recording. In the state entered into the second case 112, the possibility of newly attaching dust or fingerprints is low, so that recording is guaranteed after defect inspection. You can, of course, ban records.

On the other hand, when the first optical disc 101 is not stored in the case, the recording is not allowed but only reproduction is performed. Of course, it is possible to record after defect inspection.

Although their choice is largely due to the environment of the device of the optical disc, it is safe not to allow recording in view of the possibility of dust adhering during recording.

The setting of conditions in Table 1 is an example and may be changed as appropriate according to the use environment.

Next, the structure of the optical disc apparatus which handles the optical disc of the said structure and the case which accommodates it is demonstrated. 20 is a perspective view of one embodiment of the recording / reproducing optical disc apparatus of the present invention. In order to make understanding easy, the structure which is not related to this invention is abbreviate | omitted. In FIG. 20, 115 is a base, and the disk motor 116, the optical pickup 117, and the first case having the turntable 116a on which the first optical disk 101 or the second optical disk 104 are placed. 107 or positioning pins 118a and 118b for positioning regulation of the second case 112, spring-loaded rotatable shutter opener 119 for opening and closing the shutter 109, and case detection for detecting the presence or absence of the case. A switch 120 and a case identification switch 121 for identifying the type of case are provided.

A recording method of the information recording and reproducing apparatus based on the above-described configuration will be described.

21 is a flowchart showing an example of the recording method of the present invention.

The information recording and reproducing apparatus first determines whether the optical disc is in the case. If there is a case, then the type of case is determined.

If the result of the determination is the first case, the normal recording mode is entered. If the result of the determination is the second case, the type determination of the optical disc is made.

If the result of the determination is the first optical disc, the recording mode is recorded after defect inspection, and if it is the second optical disc, the normal recording mode is entered.

On the other hand, if there is no case, the type judgment of the optical disc is made next, and if the first optical disc is used, the recording is prohibited. If the result of the determination is the second disc, the normal recording mode is entered.

The specific operation of this recording method will be described with reference to FIG. FIG. 22 is a view showing a case in which an optical disc is stored or an optical disc alone is mounted on an optical disc apparatus for recording and reproducing. FIG. 22 (a) or FIG. 22 (b) or second case when the first case 107 is mounted In the case where 112 is mounted, FIG. 22 (c) shows a case where the first optical disk 101 or the second optical disk 104 is mounted.

First, an operation of attaching the first case 107 in which the first optical disk 101 is accommodated in the optical disk device will be described. When the first case 107 is attached to a case holder (not shown) in FIG. 22 (a) and inserted in the direction of the arrow A, the shutter opener 119 engages with the opener recess 109a of the shutter 109, The shutter 109 moves in the direction which exposes the opening 108. The first case 107 is lowered by a loading mechanism (not shown) after the opening 108 is completely exposed, and the positioning pins 118b are fitted with the positioning pins 118a fitted to the positioning holes 110. ) Abuts on the upper surface of the first case 107 to complete the mounting of the first case 107. At this time, the disc motor 16 and the optical pickup 17 are inserted into the opening 108, and the first optical disc 101 is mounted on the turntable 116a. In addition, the case detection switch 120 abuts on the upper surface of the first case 107 and the case identification switch 121 is in contact with the closed case identification hole.

The optical disk device recognizes that the first case 107 is mounted by the detection signals from the case detection switch 120 and the case identification switch 121. Thereafter, the disk motor 116 is rotated, and the optical pickup 117 is moved to a predetermined place by an optical pickup transport means (not shown), whereby the optical disc identification code in the information track 2 of the first optical disk 101 is removed. Read it.

By the above operation, the optical disc apparatus recognizes that, among the six types of use states shown in Table 1, it is the first optical disc 101 stored in the first case 107 which cannot withdraw the disc. The system is switched to record information on the first optical disc 101 or to reproduce the information. The same applies to the first case 107 in which the second optical disc 104 is accommodated.

Next, an operation of attaching the second case 112 in which the first optical disk 101 is accommodated in the optical disk device will be described with reference to FIG. 22 (b). Since the basic operation is the same as that in Fig. 22 (a), only the other operation will be described. Since the case identification hole 114 penetrates the 2nd case 112, the case identification switch 121 enters in a case identification hole, and does not contact a case. Therefore, the case identification switch 121 is different from the operation of the first case 107. The optical disk device identifies that the second case 112 is mounted from signals of both the case detection switch 120 and the case identification switch 121. The first disc 101 is identified by the above-described operation. After that, the system is switched to a recordable mode after defect inspection, and information is recorded or reproduced on the first optical disk 101. FIG. In the case of the second case 112 in which the second optical disc 104 is accommodated, the normal recording mode is enabled.

Finally, the operation in the case where the first optical disc 101 is mounted alone in the optical disc apparatus will be described with reference to Fig. 22C. When the first optical disk 101 is mounted on a case holder (not shown), the first optical disk 101 is lowered by a loading mechanism (not shown), and the first optical disk 101 is placed on the turntable 116a of the disk motor 116. The shutter opener 119 is configured such that the shutter opener 119 does not come into contact with the first optical disk 101 when the first optical disk 101 is moved. In addition, since the case detecting switch 120 and the case identification switch 121 are not in contact with the first optical disc 101, the operation of the 22nd (a) is different from that of the 22nd (b), and the optical disc apparatus It can be recognized that there is no case. The first disc 101 is identified by the above-described operation. After that, the system is switched to a non-recordable mode to reproduce the information of the first optical disc 101. When the second optical disc 104 is used alone, it becomes a normal recordable mode.

In the present embodiment, the case of two different functions has been described, but it goes without saying that even if there are only one type of case and three or more functions of the disc, the same configuration can be used.

In addition, the conditional recording in the present invention has a method such as post-record verification in addition to the above-described defect inspection.

In addition, the present embodiment describes a system of an optical disc for recording and reproducing, but it is also applicable to a system using an information carrier for recording and reproducing other than an optical disc.

Next, the case where the second invention is applied to the above-described jukebox will be described. This box is only recorded without a case, so the case shown in Table 2 is considered.

In the case of the first optical disk, it is not known whether the first optical disk originally existed in the box, or is drawn out from the second case and stored in the box, so recording is prohibited or recording after defect inspection is preferable.

In the case of the second optical disk, of course, normal recording is acceptable.

In addition, when a management area for writing management information for identifying whether the medium is used in the normal recording method or the medium is used in the special recording method is provided on the first optical disc, the jukebox reads the management information to record the normal recording. Of course, you can choose a special record.

Second Embodiment

Next, another embodiment of the media identification information unit of the present invention will be described. Fig. 23 is a diagram of an optical disc for recording and reproducing according to another embodiment of the present invention. In Fig. 23, 121 has a spiral-shaped continuous information track for recording and reproducing information on a first optical disk which performs conditional recording such as recording prohibition or recording after defect detection in a single use state, and input of the light beam from the optical pickup. The label 122 which absorbs a predetermined light wavelength is printed on the surface opposite to the surface, and the printing portion constitutes the media identification information portion of the first disk 121. 123 is a second optical disk capable of normal recording even in a single use state, has an information track similar to that of the first optical disk 121, and has a label 122 and an optical wavelength at the same position as the label 122 of the first optical disk 121. The label 124 which differs in absorption is printed, and the printing section constitutes the medium identification information section of the second disk 123.

On the other hand, the optical disk device includes a light receiving element 125 as shown in FIG. 24, and the light beam from the light emitting element 125a is reflected by the label 122 or the label 124 to the light receiving element 125b. It is arrange | positioned so that it may inject. The light receiving element 125b has a high light receiving sensitivity near the absorption wavelength at the label 122.

As a result, when the first optical disk 121 is mounted, the light beam of the light emitting element 125a is absorbed and reflected by the label 122, so that the output from the light receiving element 125b is reduced. In one label 124, since the absorption of the predetermined wavelength is small, the output from the light receiving element 125b is increased. By the size of this output level, the optical disc apparatus can identify whether it is the first optical disc 121 or the second optical disc 123. In addition, such a label is visible, and the type of the optical disc can be discriminated, and the user can easily discern the disc.

Third Embodiment

Another embodiment of the media identification information section of the present invention will be described. 25 is a diagram of an optical disc for recording and reproducing according to another embodiment of the present invention. In FIG. 25, reference numeral 131 denotes a second optical disk capable of normal recording even in a single use state, and a coating film 132, which is hard to adhere dust or fingerprints, is provided on the input surface of the light beam from the optical pickup. The surface of the first optical disk and the optical wavelength absorption are configured differently.

On the other hand, the optical disk device includes a light emitting element similar to the light emitting element 125 shown in FIG. The light beam from the light emitting element is arranged to be reflected by the coating film 132 to be incident on the light receiving element, and the light receiving element has a high light receiving sensitivity near the absorption wavelength in the coating film 132. Even in such a configuration, the same effects as in the second embodiment can be obtained.

Next, another Example of this invention is described using drawing.

The present invention is also an invention in the case where a special optical disc that can be recorded even when taken out from a case is also subjected to recording and reproduction by performing special processing on the surface of the optical disc.

Further, in the present invention, when an optical disc whose recording is not taken out from the case is an object to be recorded, the above-described history determination is made, that is, the history of the withdrawal from the case is examined, and the result Accordingly, the recording mode is appropriately switched, for example, normal recording is performed, and recording is prohibited, or conditional recording such as a defect inspection late record or post-recording inspection is performed.

In short, the present invention provides a history determination step of determining whether or not the medium has been withdrawn, by using an identification unit having history information of whether or not a medium capable of recording and reproducing the information stored in the case has been withdrawn from the case; Indicates that the medium is the first recording / reproducing information medium for which recording in case use is required, the information is recorded on the medium at all times or as long as a predetermined condition is satisfied. After verifying that the information is correct or inspecting the defect of the medium, the information is recorded or prohibited from recording on the medium, and the medium is a second recording / reproducing information medium for which recording in case use is not necessarily required. In this case, the information recording method is characterized in that it comprises a verification step of normal recording.

Further, the present invention further provides a method for determining whether or not the medium has been withdrawn, by using an identification unit having history information of whether or not a recordable / reproducible medium of information stored in the case has been withdrawn from the case; If the result indicates that the drawing is effected, if the medium is the first recording / reproducing information medium requiring recording in case use, the information is recorded on the medium at all times or as long as a predetermined condition is satisfied. For verifying that the corrected information is correct or inspecting a defect of the medium, recording the information on the medium, or prohibiting the recording, and for recording the second recording which does not necessarily require recording in use of the case. In the case of an information carrier, it is an information recording apparatus characterized by including verification means for performing normal recording.

In addition, of course, if the determination result does not indicate that the drawing is made, the normal recording is, of course.

As described above, according to the present invention, it is possible to use the recording / reproducing information medium under a predetermined optimal recording / reproducing condition in various use states in which the recording / reproducing information medium having different functions is used alone or in a case. As a result, the system handling the recording / reproducing medium can be expanded while ensuring the reliability of the recording and the compatibility between the systems.
