Description

Cartridge having opening and closing recognition groove and driving method thereof

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to the field of optical recording and reproducing of digital data on a disc. The present invention relates to an adjustable cartridge and a driving method thereof.

In this case, the open state of the disc means that the disc is removed from the cartridge and put into the case after being used. The inspection state means that the disc is inserted into the case and checked or re-confirmed for contamination and defects. It means that the defect is corrected in accordance with the appropriate defect management method suggested in the above.

Most high density optical recording and reproducing apparatuses use cartridges because recording operations requiring high recording power are much less stable than read operations due to the influence of fingerprints and scratches. In the DVD-RAM drive device, a cartridge is used to protect the disk from scratches and fingerprints and to maintain stability during recording.

However, the problem that occurs while using the cartridge is a thinner notebook type computer (notebook) computer, because of the thickness of the cartridge has a limitation in making it thin when using the cartridge.

Therefore, in order to implement a thin playback device, it is necessary to use a naked disk state. However, in order to use in a disk state, a verification process of verifying recorded data after recording must be performed due to the influence of fingerprints, wounds or dust.

However, the verification process has the advantage of improving the stability of the data by detecting areas that are temporarily or permanently unusable due to fingerprints, wounds, or dust, etc. There is a problem in that the access time of the driver is long due to the process of verifying whether the data is correctly recorded compared to the stored recording data.

On the other hand, in the case of a disc in a cartridge, since the disc is protected from dust, fingerprints, or scratches, there is a risk that a recording error may occur even if the recorded data is continuously read without verification after verifying the unusable area of the disc. Since most recording and reproducing apparatuses employ a cartridge, verification is not required after recording.

The DVD-RAM standard, however, defines three cartridge types. In addition, it sets whether the disc is removed from the case, and the recognition groove is defined as an A1 sensor hole, and in the case of a double side, only the A1 and B1 recognition grooves are corresponding to both sides.

The cartridge of the first type has a structure in which single-sided or double-sided discs can not be loaded, and the second type of cartridge has a single-sided disc. The A1 recognition groove, which recognizes that the disc has been ejected, is changed to an open state so that it cannot be closed again, so that the disc is removed from the case. The third type of cartridge has a structure in which the A1 recognition groove, which determines whether the disc is taken out of the case, is opened from the beginning so that the disc can be freely taken out of the case and placed in the case. Here, the cartridge is composed of a disc and a case, and the disc in the case is collectively referred to as a cartridge.

By the way, according to the specification 1.0 of the DVD-RAM, the second type of cartridge and the third type of cartridge once taken out are supposed to be used under the same conditions as the NaDisk. That is, the second type of cartridge, in which the disk has been removed from the case once, is in the same condition as the third type of cartridge, and the disk mounted in the cartridge of this type can accurately determine the condition of dust, fingerprints or wounds. Since the data is to be handled under the same conditions as the Na-disc, a verification process is required after recording, which causes a problem that the processing speed of data is reduced during recording and reproduction.

Table 1 below shows the types of cartridges and the corresponding A1 recognition grooves.

Cartridge type Initial state When a disc is ejected Reinsert the disc Usable Disc Type 1 Closed Unable to take out Not applicable Single sided and double sided Type 2 Closed Open automatically Keep open section Type 3 Open Keep open Keep open section

By the way, as shown in Table 1 above, in the case of the second type cartridge and the third type cartridge in which the disc has been once removed from the case, the disc is pulled out even though the disc is substantially in a condition protected from the case. Due to the possibility of being dropped out, the use of the same condition as the nadisk caused the problem that the advantages of the cartridge using the case cannot be utilized.

In order to solve the above problems, it is an object of the present invention to provide a cartridge having a recognition groove that can be opened and closed according to the disc open state and the inspection state.

Still another object of the present invention is to provide a cartridge driving method capable of controlling the open position of the recognition groove in the cartridges of the second type and the third type to the closed position after checking the disc state.

In order to achieve the above objects, the cartridge according to the present invention is a cartridge equipped with a disc capable of recording and reproducing, and controls the opening and closing of the recognition groove according to the state of the disc and the recognition groove for determining whether the disc is ejected from the cartridge. It characterized in that it is provided with an opening and closing adjustment means.

A method of driving a cartridge according to the present invention includes a method of driving a cartridge on which a disc is mounted, comprising the steps of: determining whether a recognition groove of a cartridge to be inserted indicates a first state that the disc has been ejected from the cartridge; And if the recognition groove is in the first state, performing a verification process and controlling the recognition groove to switch to the inspection state when the verification process is completed.

In FIG. 1, the position of the A1 recognition groove 263, the position of the sensor lever 220 for opening and closing the position, and the relative position of the open cover 250 for removing the disk from the case are shown. have. In addition, the protect lever 252 opens and closes the write preventing groove 262 which is generally employed to prevent the user from erasing or overwriting a disc containing important contents by a wrong operation.

Here, the A1 recognition groove 263 is oval, and has a structure that can open and close the position of the A1 recognition groove 263 by the sensor lever 220 is the most distinguishing feature from the conventional cartridge.

Figure 2 is an exploded perspective view showing in detail the assembled state of each part of the cartridge according to the present invention, first, the top cover (260) and bottom cover (270) of the cartridge (open cover (270), respectively) It is configured to be assembled through the support holes (261, 271) to support while rotating and engaged with the rotary shaft 251 of the open cover 250 so as to be opened by the rotational movement in the assembled state (250).

The sensor lever 220 is assembled through the sensor lever support hole 264 in the upper cover 260 and the sensor lever support hole 274 in the lower cover 270, respectively. The tension part 223 contacts the side surfaces of the upper cover 260 and the lower cover 270, respectively, to apply a constant tension, so that the A1 recognition groove 263 is not opened or opened. The opening and closing port 222 is positioned in the open direction.

On the other hand, the open cover 250 has a first locker (254) and a second locker (253), respectively, the first locker (254) each of the upper cover 260 and the lower cover (270) Along with the locking grooves (265, 275) serves to prevent the open cover 250 from being opened under normal use conditions, when the user needs to open the open cover 250 to eject the disk through the locking grooves (265, 275). The open cover 250 can be opened from the case by pushing the locker 254 to the inside of the case to release the lock state.

In addition, the second locker 253 in the state in which the open cover 250 is closed, as shown in the plan view of Figure 3 to create a jaw with elastic in the intermediate position of the A1 recognition groove 263 of the sensor lever 220 When the opening and closing hole 222 comes to the closed position serves to support the opening and closing hole 222 with a sufficient force not to be returned by the elasticity of the tension portion 223 of the sensor lever 220. 4 is a plan view illustrating the sensor lever 220 and the opening and closing port 222 in the open cover 250 is open.

Meanwhile, the protect lever 252 of FIG. 2 is configured to close or open the detection position of the write preventing groove 262 by the combination of the elasticity of the protect lever 252 and the locking jaw 255 together with the locking jaw 255. have.

The structure as shown in FIG. 2 capable of opening and closing the A1 recognition groove 262 described so far is merely an example, and there may be other examples. In addition, there may be an application example in which the user closes the recognition groove after performing the verification process of automatically opening the A1 recognition groove (or B1 recognition groove) on both sides of the double-sided disk and checking the defect.

On the other hand, the A1 recognition groove in the conventional second type cartridge is changed to the open state once the disc is removed from the case and is not closed.In the third type cartridge, the A1 recognition groove is always open. In the present invention, when the open cover of the case is opened, the A1 recognition groove is automatically opened and maintains the open position even when the open cover is closed, but the user performs a certification or recertification. By making it into the closed position, it is possible to solve the problem of lowering the recording speed by verification during recording.

That is, the physical form and function of the case for the existing second type and third type cartridges among the types of cartridges proposed by the present invention are the same, except that the second type of cartridge can be recorded without verification. Redefining, the third type of case redefines the cartridge to be verified at the time of writing, suggests conditions that can be recorded without verification, and if these conditions are met, the user can close the A1 recognition groove again. It is possible to improve the recording speed by providing a structure that is present.

Therefore, the condition of using the cartridge even without verification proposed in the present invention is a case where the disc is once taken out of the cartridge.

Cartridge type Initial state If you eject the disc Reinsert Disk After verification Type 1 Closed Unable to take out Not applicable Keep closed Type 2 Closed Open automatically Keep open User closed Type 3 Open Keep open Keep open User closed

In the present invention, in order to solve the problem of slowing down the disc when the disc is removed from the case once from the existing second type and the third type of cartridge, the verification process is performed at the same time as the disc. For cartridges of the second and third types, the A1 recognition groove, which recognizes whether the disc has been ejected, is automatically opened when the disc is ejected, and after checking the disc's status, the user closes it and the same as the second type cartridge that was not ejected. It was possible to record on condition. This will be described with reference to the flowchart shown in FIG. 5.

In Fig. 5, when the disc is removed from the case once from the cartridge of the second or third type and the cartridge into which the disc is inserted is inserted again (step S101), it is determined whether the A1 recognition groove is in the open position (step S101). Step S102).

If the A1 recognition groove is in the open position at step S102, it is determined whether to perform a check process for determining a defect state (step S103), and then a check process is performed (step S104).

The verification process of the present invention performs a verification process performed according to the format defined in the DVD-RAM standard, but unlike the initialization process of ignoring previously recorded data, A revalidation process that maintains and confirms should be performed. In addition, if a defect portion of a predetermined level or more is found in the step S104 of performing the reconfirmation process, the method may further include informing the user of the defect and generating information recommending that the disk be decontaminated again in an appropriate manner. You may. The procedure or processing method for the re-validation process is easily understood and implemented by those skilled in the art, and detailed description thereof will be omitted.

If the recognition groove is recognized in step S102 the cartridge is inserted in the open position may further comprise the step of generating a recommendation information that can increase the speed of use if the user re-check process.

When the reconfirmation process is completed, if the A1 recognition groove is set to the closed position, information is generated that can increase the processing speed of data without verification (step S105). After the re-checking process is completed, the A1 recognition groove of the cartridge is placed in the closed position, and then proceeding to step S102, the cartridge can be used to perform the recording operation without verification.

On the other hand, if the A1 recognition groove is in the closed position in step S102, the cartridge performs a recording operation without verification (step S106). If the A1 recognition groove is in the open position in step S103 and does not go through the verification process, the recording operation is performed while verifying (step S107). Step S107 is for corresponding to the third type of cartridge.

In summary, if the disc was removed from the second type of cartridge or used as a disk, or if a disk that was originally used as a disk was inserted into the cartridge (third type of cartridge), the user should contact the disk manufacturer before inserting the cartridge. Defects identified by defects such as dirt, fingerprints, etc. on the disc are removed in the case and the disc is placed in the case. When the processing information is recorded in accordance with the disc defect management method specified in the DVD-RAM specification, the A1 recognition groove can be closed again, thereby preventing the data processing speed due to verification every time it is used. Can be.

In the above description, the case of using the A1 recognition groove defined in the DVD-RAM standard has been described as an example. However, in order to achieve the same purpose, a new recognition groove may be set up, or an A3 recognition groove may be used, which is defined in the DVD-RAM specification but whose function is not defined. In the case of using a new recognition groove or A3 recognition groove, it is possible to distinguish that the disc is processed again so that the user can use the disc without verification while maintaining the function of the A1 recognition groove to check the state of the original maker enclosed in the case. There is an advantage.

However, if the above problem is solved by using a new recognition groove or A3 recognition groove, record the case where the position of the new recognition groove or A3 recognition groove is set to the closed position in the current DVD-RAM specification. It is necessary to set it to the state that needs to be verified and to set the state that the opening does not need to be verified at the time of recording, and when the disc is removed from the case and reinserted, the recognition groove should be set to the closed position automatically. Such a setting method is easily understood and implemented by those skilled in the art, and detailed description thereof will be omitted.

The conditions for using a new recognition groove or A3 recognition groove are summarized in Table 3 below.

A1 Recognition Home New home or A3 condition Closed Does not matter The disc has never been removed from the case Record without verification Open Closed The disc was removed from the case and no action was taken. Record verification required Open The disc has been removed from the case and the appropriate action (cleaning and defect checking) Record without verification

On the other hand, the case conforming to the DVD-RAM standard has a write-protection recognition groove that functions to prevent recording of the disc. Corresponds to reference numeral 262 in FIG. 1.

This write-protect recognition groove serves to protect the data recorded on the DVD-RAM in the cartridge state from unwanted recording. However, even in the case of a disc that is write-protected, it is a general implementation method to configure the recognition groove of a type that can be opened and closed in order to set it back to a recordable state if the user desires it again.

On the other hand, even in the case of the recognition groove proposed in the present invention has a structure that can be opened and closed there may be a user may be used incorrectly as there are a plurality of recognition grooves that can be opened and closed on the case. In order to solve this problem, the recognition groove for preventing the recording and the recognition groove for confirming the opening state of the case as shown in FIGS. 6, 7 and 8 have a recognition groove in which opening and closing is controlled by one openable sensor lever. Suggest.

That is, the recognition grooves disclosed in FIGS. 6 to 8 open and close two recognition grooves, that is, a recording prevention recognition groove and a recognition groove for confirming the open state of the case using only one sensor lever. This allows one sensor lever to move to the record-protected position, or to display an open or verified state even if recording is possible, so that two openable recognition grooves can be linked to the user's position as one linked recognition structure. As a result, it is possible to reduce the possibility of malfunction, and can be easily implemented mechanically, thereby increasing the reliability.

6 to 8, a structure for opening and closing two recognition grooves by one sensor lever is described. One sensor lever supports opening and closing means for blocking two adjacent recognition grooves and returns them to a desired position when opening and closing. The sensor lever 601 formed on the cover to be able to come up, the locking jaws 602 and 603 formed on the case to be fixed at the moved position when the sensor lever is moved left and right, and the sensor lever 601 It is composed of an oval recognition groove 604 integrating two recognition grooves (605, 606) that can be opened and closed by.

6A and 6B are a plan view and a side view showing a state in which only the write preventing recognition groove 605 is closed, and FIGS. 7A and 7B show an open state with the write preventing recognition groove 605 in FIG. 8 is a plan view and a side view of the closed state recognition grooves 606 that can be determined, and FIGS. 8A and 8B are a plan view illustrating a closed state of only the recognition grooves 606 determining the open state. Side view. The operation of the recording / playback apparatus according to the closed and open states of the recognition groove is summarized in Table 4 below.

Record Recognition Home Open status recognition groove Operation of the recording and playback device Open Closed Record prevention Closed Open Record without verification Closed If the A1 recognition groove is open, record verification is required.

That is, as shown in FIG. 8, when the recording prevention recognition groove 605 is in the open position, it is in a recording protection state and thus cannot be recorded. There is no need to determine whether or not verification is performed at the time of recording.

When the write protection recognition groove 605 is in the closed state, as shown in FIGS. 6 and 7, the open state recognition groove 606 is opened in the closed state and the closed state recognition groove 606 as shown in FIGS. 6 and 7. As shown in FIG. 6, the open state recognition groove 606 is set to a state of recording without verification in the open state, and the open state recognition groove 606 is closed as shown in FIG. 7. May determine that record verification is required. When the two recognition grooves proposed in the present invention are integrated, there may or may not be A1 and A3 recognition grooves, or there may be only A1 recognition grooves.

When the cover of the case is opened and closed again, as shown in FIG. 7 by the action of the sensor lever 601 and the locking jaws 602 and 603 protruding from the case, the cover is automatically returned. Automatically know that verification is needed.

FIG. 9 is a flowchart of a method of driving a cartridge having a recognition groove in which the write protection recognition groove and the open state recognition groove shown in FIGS. 6 to 8 are integrated. When the disc from the cartridge of the type or the third type is once removed from the case and the cartridge into which the disc is inserted is inserted into the driving device (step S201), it is determined whether the write-protect recognition groove is opened (step S202).

If the write protection recognition groove is in the open state in step S202, it is set to the prohibition state in which data cannot be recorded (step S203). Otherwise, if the write protection recognition groove is in the closed state, it is determined whether the open state recognition groove of the case is open. (Step S204).

If the open state recognition groove is in the open state in step S204 and performs a recording operation without a verification process (step S205), and if the open state recognition groove is in the closed state to determine whether to perform a confirmation process for determining a defect state (step S206), If it is determined that the verification process is performed, the verification process is performed according to the format defined by the DVD-RAM standard.However, unlike the initialization process of ignoring previously recorded data, the verification process is performed while maintaining the previously recorded data. A reconfirmation process is performed (step S207).

In the case where a defective portion of a predetermined level or more is found in step S207, the method may further include informing a user of this and generating information recommending that the disk be decontaminated once again in an appropriate manner. In addition, in operation S204, when the open state recognition groove recognizes the cartridge inserted in the closed position, the method may further include generating recommendation information indicating that the user may increase the use speed by performing the reconfirmation process.

When the reconfirmation process is completed, if the open state recognition groove is set to the open state, it is not necessary to perform a verification process, thereby increasing the processing speed of data, thereby generating information for opening the open state recognition groove (step S208). After the recognition groove of the cartridge, which has been re-checked, is placed in the open position, the process proceeds to step S203 to use the cartridge to perform a recording operation without verification. If the result determined in step S206 is not the confirmation process, the recording operation is performed while verifying the open state recognition groove (step S209).

In the present invention, when the open cover is opened, the recognition groove is automatically changed to a state in which it can be determined to be opened, and then the recognition groove is switched to a corresponding state after being checked or re-checked to check for defects on the disc in the state of being put back in the case. Providing a cartridge having a structure capable of making it possible to prevent a recording error even without verification at the time of recording has an effect of further increasing the processing speed of data.
