Example

A disk device according to an embodiment of the present invention will be described below. FIG. 1 is a block diagram of a disk device according to this embodiment. The basic configuration of the disk device includes a base body 10, a lid body 19, a chassis exterior 23, a disk housing inlet 11, a connector 12, a traverse 30, a printed circuit board 14, a spindle motor 31, a pickup 32, and a driving means 33. The chassis exterior 23 is composed of a base body 10 and a lid body 19 and a force. The front surface of the lid 19 is formed with a disk inlet 11 for directly inserting a disk, and the connector 12 is disposed on the rear surface of the chassis exterior 23. The base body 10 is provided with a traverse 30 and a printed circuit board 14. The traverse 30 holds the spindle motor 31 and the disk, and rotates and drives the disk to perform recording / reproducing operation. Also, the holding state force releases the disk 32 and the drive means 3 for moving the pickup 32. 3 and hold.

[0011] The disk device is a disk loading control system, and a disk insertion detecting means 24 for detecting that the disk has been inserted into the disk device, and performing a profiling operation by inserting the disk. The disk loading standby state detecting means 25 for detecting a possible state and the disk insertion detecting means 24 drive the loading motor to the inside of the disk device based on detection information that the disk has been inserted into the disk device. The disk loading means 26 that is rotated by the spindle motor 31 and rotatably mounted on the spindle motor 31, the loading completion detection means 27 that detects the state that the disk loading means 26 has completed the disk loading operation, and the disk inside the disk device A disk presence / absence detecting means 28 for detecting presence / absence, and a disk And a mechanical position detector 29 for detecting a mechanical position of the loading means 26, Ru.

[0012] The disc insertion detection means 24 is configured by a switch that is turned off when a disc is inserted and is turned on when the disc is inserted. The disk loading standby state detection means 25 is composed of a switch that is turned on when the disk is in a loading standby state and is turned off in a state other than the loading standby state. The loading completion detection means 27 is composed of a switch which is turned on when the disk is completely loaded by monitoring the disk loading state, and is turned off in other cases. The disk presence / absence detecting means 28 is composed of a switch which is turned off when there is a disk inside the disk device and turned on when there is no disk. The mechanical position detection means 29 detects the mechanical position when the mechanism of the disk loading means 26 is moving during the loading operation, and the standby position and the loading completion position between the loading completion position and the eject completion position. It consists of switches that are turned on when in between and turned off otherwise.

[0013] In addition, as a disk discharge control system, a discharge switch 43 for instructing disk discharge, and the instruction of the discharge switch 43 cancels the mounting state of the disk to the spindle motor 31 and loads the disk to the outside of the disk device. A disc ejection means 44 that ejects by driving the ding motor and a disc ejection state detection means 45 that detects a state in which the disc is ejected by the disc ejection means 44 are provided. The disc ejection status detection means 45 is turned on when the disc ejection is completed, and turned off when the disc ejection is not completed. It is composed of switches.

Next, the operation will be described with reference to FIG. FIG. 2 is a flowchart for explaining initialization operation processing of the disk device according to the embodiment of the present invention. First, when a power-on or initialization operation is requested, basic initialization operation processing is performed in the disk device. In the slot loading type, it is necessary to perform the eject operation once after the power is turned on. The purpose is to return the disk loading mechanism to the normal standby position, which may stop at an abnormal position when there is no disk. In the initialization operation, as shown in FIG. 2, first, the disk presence / absence detection means 27 determines whether or not a disk exists in the disk device (step 1), and detects that the disk exists in the device. In some cases, the mechanical position is always at the loading completion position, so the initialization process in the direction of the register is not performed, and a spin-up process is performed to enable recording and playback (step 2).

[0015] On the other hand, if there is no disc, the eject operation is started (step 3), the disc ejection means 43 is operated, and the disc ejection operation is performed until the disc ejection state detecting means 44 detects the disc ejection state. (Step 4). When the disc ejection state is detected by the disc ejection operation of the disc ejection means 43, the disk loading means 26 is operated to move to the loading operation (step 5), and the disk loading standby state detection means 25 enters the disk loading standby state. Operate until it is detected and enter the disk loading standby state (step 6) and finish initialization.

[0016] It should be noted that since a mechanical movement operation is always performed to return to the standby position when the power is turned on, the loading sound is felt loud when the power is turned on. Therefore, it is preferable to set the driving voltage of the loading motor 60 in the initialization process to be lower than the driving voltage of the normal disk loading process or the ejection process. In actual processing, the discharge processing routine can be used as it is, and the drive voltage during discharge can be reduced. During the power-on power initialization process, even if the eject switch or disk detection switch is detected, an event is not issued and held for initialization, and when the initialization is completed, the hold is released. .

Next, the loading operation processing of the disk device will be described with reference to FIG. FIG. 3 is a control flowchart of the loading operation process. The disc is inserted into the disc inlet 14 When this happens, the disc detection switch as the disc insertion detection means 24 turns off when a disc is inserted, and turns on when no disc is inserted, so the insertion of a disc is detected by monitoring its polling. (Step 11). Next, after removing the disk chattering, the loading motor 60 of the disk loading means 26 is driven to the loading side to start the loading process (step 12). It is also possible to detect the insertion of a disc after removing chattering (step 11). During the loading process, the loading completion detection means 27 and the disk presence / absence detection means 28 are monitored and the driving operation of the loading motor 60 is controlled. In addition, while monitoring the mechanical position detecting means 29, the position of the loading mechanism at that time is grasped, and the driving voltage of the loading motor 60 is varied for each position of the loading mechanism to perform fine loading control.

[0018] During the execution of the loading process, the disk rotation process (step 13) and the pickup inner circumference feed process (step 14) are performed in parallel with the driving of the loading motor 60. The disk rotation process is performed to perform a chucking operation multiple times. In other words, there is a possibility that the chucking may fail in the one-time checking operation, so after reaching the position where the loading mechanism performs the chucking during the loading process, return the loading mechanism to the ejection direction and drive again in the loading direction. Then, the second chucking operation is performed, and then the loading motor 60 is driven so as to perform a plurality of chucking operations by repeating this operation as necessary. At this time, in the disk rotation process, the disk is rotated by the spindle motor 31 between the first chucking operation and the second chucking operation so that the chucking operation is not repeated repeatedly at the position of the chucking claw where it is difficult to perform the chucking. The pickup inner circumference feeding process is a process of moving the pickup in the inner circumference direction of the disk during the loading process in order to shorten the disk spin-up time.

[0019] The loading completion detection means 27 determines whether or not the loading is completed (step 15). When the loading completion is detected, in order to prevent the back electromotive voltage from being generated in the loading motor 60, 0 volts The braking operation of the loading motor 60 is performed by driving (step 16), and the loading motor 60 is rotated in reverse to stop the repulsive loading operation immediately (step 17). Finally, the disk loading is performed so that the next disk cannot be inserted and the loading operation is not performed even if there is a request for loading again. Lock the mechanism 26 (step 18).

If necessary, after the completion of loading is detected in step 16, continue the loading operation and push in further to make sure that the disk does not come off.

Next, the disk ejection process of the disk device will be described with reference to FIG. Fig. 4 is a control flowchart of the disk ejection process. The discharge process is activated only when the discharge switch 43 is pressed or a discharge command is received. When the eject switch 43 is pressed or a eject command is detected (step 21), the disc is unmounted from the spindle motor 31 (step 22), and the loading motor 60 is ejected in the direction opposite to the loading direction. To perform discharge processing (step 23).

During the ejection process, the loading motor 60 is driven to move the position of the loading mechanism while monitoring the disk detection means 24, the disk ejection state detection means 45, and the standby position detection means 25. At this time, while monitoring the mechanical position detection means 29, the position of the loading mechanism at that time is grasped, and the drive voltage of the loading motor 60 is varied for each position of the loading mechanism to perform fine discharge control. The actual discharge process consists of two operating forces: movement of the loading mechanism in the discharge direction and return to the standby position. After moving in the eject direction, the loading mechanism is locked, and the mechanism does not move when trying to insert a disc. In order to be able to insert the next disc, it is necessary to move the loading mechanism position again in the loading direction and return to the standby position. If the discharge switch 43 is detected during the discharge process, the current discharge operation is continued without issuing an event. If a new disk ejection instruction is received during the ejection process, the current ejection process is continued.

[0021] The disc ejection status detection means 45 determines whether or not the disc ejection means 44 has finished ejecting the disc (step 24), and when it detects that the disc ejection has been completed, it detects the waiting state of the disk. It is determined whether or not the disk loading operation can be performed by means 25 (step 25). If it is detected in step 24 that the disc has not been ejected, the eject process (step 23) is repeated. If it is determined in step 25 that the disc opening operation can be performed, the loading motor 60 In order to prevent the occurrence of reverse electromotive force, the braking operation of the loading motor 60 is performed by driving 0 volt (step 26), and the reverse operation is performed to immediately stop the repulsive force loading operation (step 26). Step 27). Finally, the mechanical position of the loading force is moved to the disk insertable position so that the next disk can be inserted, and the disk loading standby state is set (step 28).

If it is determined in step 25 that the disc loading operation is not possible, it is determined that the disc has been ejected, and the eject process (step 23) is repeated again.

It is to be noted that chattering is performed as necessary before the disc ejection status detecting means 45 in step 24 judges whether or not the disc ejection is completed, or the disc loading standby status detecting means 25 in step 25 judges whether the disc loading operation is possible. It is preferable to perform the removal.

By the way, if the pickup 32 moves to the outer periphery during the discharge process, the discharge lever 100 of the disk discharge means 44 may collide with the pickup 32 and damage the pickup 32. Therefore, it is necessary to forcefully move the pickup 32 to the outer peripheral position before the discharging process. In the present embodiment, the spin-down process is performed before the discharge process, and the pickup 32 is moved in the outer circumferential direction. Whether or not the pickup 32 is moved to the outer periphery at the time of spin down is determined by whether or not the disk presence detecting means 28 detects the disk, and when the disk is detected, the pickup 32 is moved to the outer periphery and is not detected. Do not do. In this case, the chattering removal is not performed in the disk detection by the disk presence / absence detection means 28.

The outer periphery of the pickup 32 is moved using a DC motor. During the spin-down process, the recording / reproducing laser and focus are turned off, and the spindle motor 31 is turned off. When the spindle motor 31 is off, the parameters are passed so that the pickup outer periphery moves in parallel with the disk. If the current address can be acquired, the distance from the current position to the outer circumference is calculated, the number of DC motor drive pulses required for the transfer amount corresponding to that distance is calculated, and the pickup 31 is pulsed on the outer circumference by that number of drive pulses. Move by feed. At this time, the amount of movement of the pickup is monitored by the encoder, and the encoder output is Stop motor drive when no more than the amount changes.

[0024] When the current position cannot be obtained, the pickup 32 is once moved to the innermost circumference, and the pickup 31 is moved to the outer circumference by a predetermined number of fixed pulses while monitoring the encoder output from the innermost circumference. Let Even when the pickup 31 is moved to the innermost circumference, it is moved while monitoring the output of the encoder. The reason why the pickup is moved to the innermost circumference and the force is moved to the outer circumference when the current position cannot be obtained is that mechanical movement and jumping are more likely to occur when the pickup 32 is moved directly to the outer circumference than when the pickup 32 is moved to the inner circumference. Because.

In order to prevent the ejection lever from hitting the pickup lens when the disc is ejected, it is preferable to move the pickup lens downward to a predetermined position where the ejection lever does not strike.
