The conventional cartridge 31, which houses the disk (recording medium) 32, must accurately record the desired signal and must protect the disk 32 against dirt or fingerprint contamination or other defects. Therefore, the disc 32 cannot be taken out of the cartridge 31.

However, the structure in which the disk is fixed as described above does not allow the user to eject the disk and mount it on another signal reproducing apparatus, and even when the disk removing function is added, the user cannot identify whether the disk is ejected or not. The possibility of fingerprint contamination or damage from defects is unknown.

If these defects remain, the signal recording apparatus approaches the defect location of the disc and records the signal in error. If the signal recording device has a function of checking whether or not it can record a series of signals normally, when the device approaches another place on the disc for recording and then records the current signal as normal and then records the next signal. Such confirmation takes time, so the device cannot record the signal at high speed.

The cartridge of the present invention aims at allowing a user to know whether or not the disc housed in the cartridge has been taken out of the cartridge, and the signal recording device for storing the cartridge of the present invention is defective when the disc is taken out of the cartridge. The signal can be recorded without approaching the defective place of the generated disk.

In order to realize the above object, one of the preferred embodiments of the cartridge according to the present invention has the following structure: the cartridge is configured to record a signal on the medium when the cartridge is mounted in the signal recording apparatus, and the cartridge is also

1. a signal recording medium housed therein;

2. an opening for removing the medium from the cartridge;

3. An indicator indicates the possibility that the medium has never been taken out of the cartridge.

In FIG. 4, the first opening 11 is used to record a signal to the disk 2 when the disk 2 is mounted on the signal recording apparatus. The second opening 12 is provided on the side opposite to the first opening 11 and has a shape substantially the same as the first opening 11. The second opening 12 is used to record a signal to the disk 2 when the disk 2 is mounted on the signal recording apparatus. The opening 13 is provided on a surface different from the surface on which the opening windows 11, 12 are provided, and is used when the disk 2 is taken out of the cartridge 1 to the outside. The indicator claw 14 indicates the possibility of whether or not the disc 2 has been taken out of the cartridge 1. As shown in FIG. 5, the claw 14 is connected to the cartridge body 6 by the connector 15 at various points. In normal usage, as long as the connector 15 connects the claw 14 to the cartridge body 6, the claw 14 prevents the holder 16 from moving or rotating, so that the disc 2 in the cartridge 1 may not. ), The opening 13 cannot be opened.

The holder 16 covers the opening 13. The hinge 17 (FIG. 6) is mounted to the cartridge body 6, and the first end of the holder 16 is mounted to rotate about the hinge 17. As shown in FIG. The second end of the holder 16 passes through a clasp 18 that engages with the receptor 19 of the cartridge body 6 so that the holder 16 covers and holds the opening 13.

6 (a) to 6 (c) show a process of taking out the disk 2 from the cartridge of the above structure.

6 (a) shows a state in which the cartridge body 6 is incorporated with the holder 16. As shown in FIG. The user usually receives the cartridge 11 in this state. In other words, the disc 2 has never been removed from the cartridge 1 after it has been shipped from the factory.

6 (b) shows the cartridge 1 with the claw 14 removed. Cut the connector 15 with hands or scissors and remove the claw 14. FIG. 6C shows the opening 13 opened by rotating the holder 16 about the hinge 17. In the present embodiment, the cartridge body 6 is set by setting the cartridge 1 in the state shown in FIG. 6 (b), and then separating the latch 18 provided at the first end of the holder 16 from the receptor 19. After the holder 16 is removed, the opening 13 is opened. The disc 2 is now ready to be removed from the cartridge body 6.

The above structure allows the user to take out the disc 2 from the cartridge body 6. That is, the indication showing the possibility of whether or not the disc 2 has been taken out of the cartridge body 6 can be changed before taking out the disc 2. That is, the state in which the claw 14 is connected to the cartridge body 6 is changed to another state in which the claw 14 is removed. In this state, the user can take out the disk 2 from the cartridge body 6.

Thanks to the above structure, i.e., the structure of cutting the connector 15 to remove the claws 14, the user who wants to use the cartridge 1 from now on has a disc 2 stored in the cartridge 1 ), It is possible to know whether or not it has been taken out, and predict that the disk 2 may be contaminated with dust or fingerprints, or there may be some defects.

In the above structure, an opening 13 for ejecting the disk 2 is provided on a surface different from the surface on which the first opening 11 and the second opening 12 for recording signals to each side of the disk are provided. Therefore, the 1st opening 11 and the 2nd opening 12 can be made substantially the same shape. Therefore, the signal recording apparatus handling the cartridge of the present invention does not need a specific structure for reproducing signals from both sides of the disc.

In this embodiment, the first opening 11 and the second opening 12 are provided for recording and reproducing signals for both sides of the disc 2. However, when using the side of the disc or using only one side of the disc, it is sufficient to provide one opening window.

In this embodiment, the cartridge body 6 and the claw 14 can be molded integrally using resin, so that the cartridge 1 can be easily manufactured.

In the present embodiment, the cartridge body 6 is configured to be separated from the holder 5, but the cartridge body 6 and the holder 5 may be combined as long as the disc 2 can be taken out of the cartridge 1. .

Example 3

A signal recording apparatus for handling the cartridge of the present invention will be described with reference to the drawings. The same components used in the preceding embodiments have the same reference numerals, and the description thereof is omitted.

In FIG. 8, the detection unit 20 determines whether or not the disc 2 has been taken out of the cartridge 1 by detecting the adhesive tape 4 or the claw 14 which is an indicator. The retrieval unit 21 searches for an unrecordable place of the disc 2 when the detection unit 20 determines that the disc 2 may be taken out of the cartridge 1. The recording unit 22 records a signal on the disc 2. The searching unit 21 searches for a defect on the disk 2 through the pickup unit 23, and the recording unit 22 records a signal on the disk 2 through the pickup unit 23.

The detection unit 20 has components corresponding to the adhesive tape 4 and the claw 14. These components are described below:

(1) Detecting section 20 (silver colored tape) corresponding to indicator 4:

As shown in FIG. 9, the detection unit 20 of the signal recording apparatus has a light emitting element for emitting light upward and a light receiving element 25 for receiving the reflected light.

9A shows the case where the disk 2 has never been taken out of the cartridge 1. The light emitted from the light emitting element 24 is adhered to the cartridge 1 by an adhesive tape 4 After the reflected light is received by the light receiving element 25, the detection unit 20 of the signal recording apparatus identifies that the received light emission energy is greater than or equal to a predetermined amount, and the disk contained in the cartridge 1 2) proves that it was never taken out.

9 (b) shows a case in which the disk 2 may be taken out of the cartridge 1. Since the adhesive tape 4 is not stuck on the cartridge 1, the light emitting element 24 The emitted light is not sufficiently reflected so that the detection unit 20 of the signal recording apparatus cannot identify that the luminous energy received by the light receiving element 25 is higher than or equal to a predetermined level, and the disk 2 is removed from the cartridge 1. I think there may be an enemy.

If black or light absorptive non-reflective materials are preferably used on the irradiation surface of the cartridge 1, more effective error prevention can be expected. Other detection methods have been devised below.

A material having a light reflectance different from that of the surface of the cartridge body 6 or the surface of the holder 5 and the adhesive tape 4 is used. (The light reflectance of the former need not be lower than the latter light reflectance. The light reflectance may be higher than the latter. Therefore, the light emitted from the light emitting element 24 is reflected in different amounts by the adhesive tape surface and the cartridge surface or the holder surface. The detection unit 20 of the signal recording apparatus detects the difference in the reflection of the optical energy through the light receiving element 25. In this way, it can be identified whether or not the disc 2 has been taken out of the cartridge 1.

(2) Detection unit 20 corresponding to claw 14 (indicator):

As shown in FIG. 10, the detection unit 20 of the signal recording apparatus is provided with a switch 26 for identifying the possibility that the disc 2 has been taken out of the cartridge 1 or not.

10 (a) and 10 (b) show the case where the disc 2 has never been removed from the cartridge 1. The switch 26 moves upward from the normal position as shown in FIG. 10 (a) to the designated position ready for detection as shown in FIG. 10 (b). The switch 26 acts on the claw 14. The detection unit 20 thereby identifies that the disk has never been removed from the cartridge 1.

10 (c) and 10 (d) show that there is a possibility that the disc 2 is taken out of the cartridge 1. The detector 20 moves upward from the normal position to the designated position as shown in FIG. 10 (d) ready to detect from the normal position as shown in FIG. 10 (c). The switch 26 pierces the air and does not work. The detection unit 20 thereby identifies the possibility that the disc 2 has been taken out of the cartridge 1.

The operation of the signal recording apparatus using the mounted cartridge is described below:

(1) When the disc 2 has never been removed from the cartridge 11: Since the adhesive tape 4 and the claw 14 are present in the cartridge 1, the detection unit 20 detects them and detects the disc 2. Identifies that it has never been removed from the cartridge 1. Then, the retrieving unit 21 does not search for a defective place on the disc 2, and the recording unit 22 records the same signal as the normal operation of the signal recording apparatus via the pickup unit 23.

(2) When the disc 2 is likely to be taken out of the cartridge 1: The adhesive tape 4 and the claw 14 are removed from the cartridge 1, and the detection unit 20 detects this to detect the disc ( 2) identifies the possibility that it has been taken out of the cartridge 1. Then, the searching unit 21 starts searching for the defective place on the disc 2, and based on the search result, the recording unit 22 records a signal on the disc 2 except for the found defective place. In this case, of course, the recording operation can be inhibited.

This structure allows the user to know the dirt, fingerprints and other defects contaminated on the disc when the disc 2 is taken out of the cartridge 1. The device can record a signal on the disc without access to such a defective location. In other words, the structure does not record the defective place, so that the access time to the disc 2 can be reduced by avoiding recording or repeatedly accessing the signal at the combined place.

Example 4

An embodiment of an electronic device using the cartridge of the present invention will be described with reference to the drawings. While the components are described in the preceding embodiments, the same reference numerals are used to omit the description.

In FIG. 11, the display unit 27 such as a CRT or LCD displays an unrecordable capacity, a recordable capacity, or both based on a search result of the search unit 21. FIG. The display unit 27 may be connected to or separated from the signal recording apparatus directly or indirectly.

The operation of the electronic device using the cartridge having the above structure will be described here: (The same structure of the detection unit 20 of the third embodiment corresponding to the indicator adhesive tape 4 and the claw 14 is used here)

(1) When the disc 2 has never been taken out of the cartridge 1: The detection unit 20 detects the adhesive tape 4 and the claw 14 present in the cartridge 1 to detect the disc 2. Identifies that it has never been removed from the cartridge 1. Based on this determination, the display unit 27 displays the normal recordable capacity.

(2) When the disc 2 is likely to be taken out of the cartridge 1: The detection unit 20 detects that the adhesive tape 4 and the claw 14 have been removed from the cartridge 1, and thus the disc 2 is removed. Identifies the possibility that the cartridge 1 has been removed from the cartridge 1. Based on this determination, the searching unit 21 searches for an unrecordable place or a recordable place on the disc 2, and based on this search result, the display unit 27 records the recordable capacity and recording of the disc 2; Indicate impossible doses or both.

Here, a preferred embodiment of the operation of the retrieval unit 21 will be described: The pickup unit 23 records the information signal on the entire disc 2 based on the retrieval result of the retrieval unit 21. As shown in FIG. The information signal includes an error correction code, and the error can be detected when the information signal is reproduced. In the case where the detected error cannot be corrected or can be corrected by not exceeding the designated range, the sector in which the error was detected is not available, and information that the sector cannot be used is recorded in the designated place of the disc 2. .

Displaying the recorded information on the display portion 27 informs the user of the recordable capacity of the disc 2. Since this operation can be used for each track or sector of the disc 2, it is possible to record an unwritable or recordable sector or track in a designated place of the disc 2 to control the recording operation for the disc 2.

When the disc 2 is an optical disc, lasers are generally used to record and reproduce signals. In order to optimally store the information signal on the optical disc, the acceptable output range of the laser must be narrowed.

For example, in the case of a commercial recordable optical disc, the optimal power range of the laser is less than 10% of the center of power. When recording the information signal within this range, the error rate does not exceed the specified range (eg 0.00001 or less). When reproducing the recorded information signal, if the reproducing laser output changes within 50%, the error rate does not exceed the specified range (for example, 0.00001 or less).

According to the above, it is known that the acceptable range of the recording laser output is narrow while the acceptable range of the reproduction laser output is wide.

That is, once the information signal is recorded, it can be safely reproduced even if a fingerprint or the like contaminates the optical disc. On the other hand, if a fingerprint or the like contaminates the optical disc before recording the information signal, it is difficult to record the information signal. Therefore, after recording the signal on the optical disc, it is possible to take out the optical disc from the cartridge and put it in the reproducing apparatus to reproduce the signal.

The optical disc once removed from the cartridge 1 can be put back into the cartridge 1 for recording a signal by the signal recording apparatus. In this case, as described above, the apparatus searches for a recordable place before recording the signal.

The above structure allows the user to recognize defects such as dust, fingerprints, and the like, which contaminate the disc 2 due to being taken out of the cartridge 1, and know the recordable capacity or lost recordable capacity caused by the defect. Can be.

According to the cartridge of the present invention, the user can know the possibility that the disc housed therein has never been taken out of the cartridge, and can predict that such a disc is likely to have defects such as dust, fingerprints, etc. on it. Can be.

Since the signal recording apparatus of the present invention can record a signal without approaching the defective place of the disc due to dust, fingerprint, etc. generated when the recording medium is taken out of the cartridge, the signal recording device records the signal at the defective place of the disc. Can be prevented and access to the defective place can be avoided due to unrecording, thereby reducing the access time. It is also possible to prohibit recording when it is recognized that the disc has been ejected from the cartridge.

The electronic device of the present invention enables the user to know defects such as dust, fingerprints, etc. that contaminate the disk when the disk is taken out of the cartridge, so that the user can know the recordable capacity of the current disk or the unrecordable capacity lost by the defect. Can be.
