Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information recording and reproducing apparatus that records and/or reproduces and/or erases information on an information recording medium housed in a cartridge. Note that the present invention applies to optical, magneto-optical,
This includes any type of magnetic type.

[Conventional technology]

Conventionally, for example, a light beam focused on a minute spot is applied to the medium surface to cause changes in the medium surface to perform recording, or a light beam focused on a minute spot is applied to the medium surface on which information is recorded and the light is reflected. Optical information recording and/or reproduction, in which information is reproduced by changes in light, is characterized by high access speed and large recording capacity, and is expected to become widely used.

[Problem to be solved by the invention]

However, in conventional information recording and reproducing devices that perform such information recording and/or reproduction, malfunctions of the rotating means for the recording medium may occur when the loading and ejecting means for the recording medium accommodated in the cartridge operate. However, the loading or ejecting means does not stop the operation based on the detected malfunction signal.

Therefore, even if a malfunction occurs in the rotating means for the information recording medium housed in the cartridge, the loading/ejecting means for the recording medium continues to operate, so there is a problem in that both the recording medium and the rotating means are damaged. Ta.

〔the purpose〕

The present invention has been made in view of the problems of the prior art described above, and its purpose is to stop the loading/ejecting operation when a malfunction occurs in the driving means for driving the information recording medium housed in the cartridge, and to record the information recording medium. An object of the present invention is to provide an information recording and reproducing device that can prevent damage to a medium and a driving means.

[Means to solve the problem]

According to the present invention, the above object is achieved in an information recording/reproducing apparatus having means for moving a cartridge containing an information recording medium between a loading position and an ejection position; The ejecting operation is prohibited when a malfunction of the driving means of the recording medium is detected.
This is achieved by an information recording/reproducing device.

[Example] Hereinafter, an example of the present invention will be described specifically and in detail based on the drawings.

FIG. 1 is a conceptual diagram showing an overview of the information/recording/reproducing apparatus of the present invention.

In the figure, 1 is a spindle motor that rotates an information recording medium housed in a cartridge, and 2 is a sensor for detecting the rotation of the spindle motor. 3 is a diagram showing the cartridge position at the time of ejection, and 4 is a diagram showing the cartridge position at the time of loading. The cartridge is movable between IJ positions 3 and 4. Further, M in the figure is a motor that moves the cartridge to a loading position and an eject position, and C is a Tanabata control device that controls the motor.

FIG. 2 is a flowchart showing the prohibition of loading and ejecting operations during rotation of the spindle motor of the information recording and reproducing apparatus of the present invention.

As shown in step 1 in FIG.
When the control device C determines that the spindle motor 1 is rotating based on the signal of the spindle motor rotation detection sensor 2 which generates a signal as the spindle motor 1 rotates, an error is sent to the outside. Indicates occurrence and cancels the following processing. Control device C is spindle motor 1
If it is determined that is stationary, the process proceeds to Stella f2.

In step 2, it is determined whether the command input to the control device C is a loading command or an eject command, and if it is a loading command, the process advances to step 3, and if it is an eject command, the process advances to Stella f6.

In step 3, the control device C issues a loading rotation signal to the motor M.

In step 4, the spindle motor rotation detection sensor determines whether the spindle motor 1 is rotating during the loading operation. The control device C makes a judgment based on the signal No.2. If the spindle motor 1 is rotating, the control device determines that there is an error, indicates the occurrence of the error to the outside, and stops the process. If it is determined that it is not rotating, proceed to Stella f5.

In step 5, it is determined whether the cartridge has moved from the eject position 3 to the loading position 4, and if it is the loading position 4 shown in FIG. 1, the process ends. If the loading position is not 4, the loading operation continues.

In step 6, the control device C issues an eject rotation signal to the motor M.

In step 7, spindle motor 1 is
The control device C determines whether or not the spindle motor rotation detection sensor 2 is rotating. If the spindle motor 1 is rotating, the control device determines that there is an error, indicates the occurrence of the error to the outside, and stops the process. If it is determined that it is not rotating, proceed to step 8.

Stellar 768 determines whether the cartridge has moved from loading position 4 to eject position 3, and if it is at eject position 3 shown in FIG. 1, the process ends. If the eject position is not 3, the eject operation continues.

〔Effect of the invention〕

The information recording and reproducing apparatus of the present invention configured as described above is configured to prohibit loading or ejecting the cartridge when the spindle motor malfunctions, thereby preventing damage to the information recording medium and the spindle motor. can do.

Therefore, the life of the information recording medium and spindle motor can be extended.
