2. Description of the Related Art In recent years, optical discs have a high recording density, a long life of the medium because they can be recorded and reproduced in a non-contact manner, and random access is much faster than a medium such as a tape. There are many proposals such as a CD, a VLP as an example, an image file, a data file, and a document file as a recording and reproducing device. In particular, it is used as a data file, as a large-capacity portable information medium, or as an alternative to a fixed magnetic disk. However, since the optical disk has a lower operation guarantee temperature of the information recording medium than the fixed magnetic disk, various temperature rise prevention measures are taken. Further, with the downsizing and speeding up of devices, the demand for low power consumption is increasing.

As described above, although various modifications have been made to the optical disc, the condition for transitioning to the low power consumption state has hitherto depended only on the processing request interval from the computer. That is, if the processing request interval becomes long, the processing transitions to the low power consumption state and then to the operation state at the next processing request to execute the processing.

First, when the information recording medium 1 is mounted in the apparatus, the apparatus control section 15 controls the disk motor control section 6, the head control section 7, and the magnetic field drive section 10 to record and reproduce the apparatus. Transition to. In this operating state, if the time T measured by the time measuring means 14 which is cleared by the command of the interface controller 13 every time a processing request is received from the host computer 12 satisfies a predetermined condition, the head controller 7 and the disk motor The controller 6 is controlled to stop the operation of the head 4 and the disk motor 5, and the operating state is changed to the low power consumption state. If the measured temperature D input from the temperature detection unit 3 via the temperature measuring means 9 and the time T measured by the time measuring means 14 satisfy a predetermined condition, it means that the power consumption state is not already low. After checking, the head control unit 7 and the disc motor control unit 6 are controlled to stop the operation of the head 4 and the disc motor 5 to shift to the low power consumption state. When a processing request is received from the host computer 12 in this state, the low power consumption state is returned to the operating state and the processing is executed. Here, if the predetermined condition is properly selected, in the high temperature operation state, even if the time interval of the processing request from the host computer is short, the state transitions to the low power consumption state, which enhances the reliability of the device and improves the reliability of the device. It becomes possible to extend the life. The predetermined condition is that, for example, when the temperature inside the apparatus is 30 degrees Celsius, the time interval T is about 5 to 10 minutes, but the load on the apparatus is small, so T is set relatively long. Also, when the temperature inside the device is 40 degrees, the load on the device is heavy, so T can be set to a short value of about 2 to 3 minutes to improve reliability, reduce power consumption, and improve device life. is there. Further, in the above example, the state is changed to a state of low power consumption step by step, but when the time T is 10 minutes and the temperature inside the apparatus is 40 degrees or more, for example, the head 4 and the disk motor 5 are immediately passed without passing through other low power consumption. It is also effective to stop the operation of and make the state of the lowest power consumption.

First, when the information recording medium 1 is loaded into the apparatus, the apparatus control section 15 controls the disk motor control section 6, the head control section 7, and the magnetic field drive section 10 to record and reproduce the apparatus. Transition to. In this operating state, when the time T measured by the time measuring means 14 which is cleared by the command of the interface controller 13 every time the processing request is received from the host computer 12 is equal to or longer than the set time T1 stored in the storage means 11. (Step S2), it is confirmed that it is in an operating state (step S3), and the magnetic field drive unit 10
Is controlled to stop the operation of the magnetic field mechanism unit 2 and transit to the first low power consumption state (step S4). If this state continues and the time T measured by the time measuring means 14 is equal to or longer than the set time T2 stored in the storage means 11 (step S8), it is confirmed that the low power consumption state 1 is set ( In step S9), the head controller 7 and the disk motor controller 6 are controlled to stop the operations of the head 4 and the disk motor 5 and transition to the second low power consumption state (step S9). Further, the measured temperature D input from the temperature detecting unit 3 via the temperature measuring means 9 is stored in the storage means 11
Is equal to or higher than the set temperature D1 stored in (step S
5) If the time T measured by the time measuring means 14 is equal to or longer than the set time T3 stored in the storage means 11 (step S6), it is confirmed that the low power consumption state 2 is not already established (step S6). In step S7, the head controller 7 and the disk motor controller 6 are controlled to stop the operations of the head 4 and the disk motor 5 and transition to the second low power consumption state (step S10). Next, the host computer 12
When the processing request is received from (step S1), if it is the first low power consumption state or the second low power consumption state (step S11), the operation state is restored (step S1).
3), the process is executed (step S12).
Here, in the first low power consumption state, the amount of reduction in power consumption is small, but the time to return to the operating state is short. In the second low power consumption state, the amount of reduction in power consumption is large, but the time to return to the operating state is longer than that in the first low power consumption state.
If the set time T1 is selected to be sufficiently larger than the set time T2, the first low power consumption state transitions even during a short period of no processing request, reducing power consumption, but from this state to the operating state. Since the recovery time is short, the influence on the processing time of the device is slight. As described above, according to this embodiment, the power consumption is reduced while suppressing the influence of the return time to the operation state added to the processing time requested by the host computer. The present invention provides an information recording / reproducing apparatus having a low power consumption state in which deterioration of performance due to the low power consumption state is suppressed to a minimum. When the temperature is equal to or higher than the set temperature D1, the set time T is sufficiently small.
If you select 3, it will transition to a low power consumption state even if the processing request interval is short, avoiding operation at high temperature,
This increases the reliability of the device.

In the embodiment of the present invention, the information recording / reproducing apparatus using the optical disk having the magnetic field mechanism was used for description, but the invention is not limited to this, and the phase change type or dye type optical disk which does not require a magnetic field is used. It is obvious that the present invention can be applied to a disk-shaped magnetic recording medium having a similar shape or a device having a similar information recording / reproducing function using another type of information recording medium such as a card or a tape. In the embodiment, the first low power consumption state 1 is described as the operation state of the magnetic field mechanism unit 2 being stopped, and the second low power consumption state is described as the operation state of the head 4 and the disk motor 5 being stopped. The present invention is not limited to this, and for example, by reducing the rotation speed of the optical disk to about half, it is possible to reduce the current consumption due to the wind loss of the disk motor and to suppress the acceleration of the position control servo system of each lens such as focusing and tracking to a low level. It is possible to select and use various low power consumption states such as selecting as one of the possible low power consumption states.
