[0002]

2. Description of the Related Art FIG. 3 shows a magnetic recording / reproducing apparatus provided with a conventional automatic adjustment control device, which has an operation specifying section 1, an automatic adjusting operation specifying means 2, and a magnetic recording / reproducing apparatus 3.

[0003] 1 is an operation designating unit used by a user to normally operate the operation of the magnetic recording and reproducing apparatus. 2 is an automatic adjusting operation designating means for operating the operation of the magnetic recording and reproducing apparatus in the automatic adjustment mode. Is an operation control unit for controlling the operation of the magnetic recording / reproducing apparatus.

Here, an automatic adjustment control operation of a magnetic recording / reproducing apparatus including a conventional automatic adjustment control device will be described.
In the state of the normal operation mode other than the automatic adjustment mode, the operation control unit 1 creates operation specification information for requesting a certain operation of the magnetic recording and reproducing apparatus by operating the operation specification unit 1 by the user, and stores the operation specification information. It is transmitted to the operation control unit 3. The operation control unit 3 receiving the operation designation information switches the magnetic recording / reproducing apparatus to the designated operation based on the operation designation information.

In the state in which the mode is shifted to the automatic adjustment mode, the automatic adjustment operation designating means 2 causes the magnetic recording / reproducing apparatus to operate the operation corresponding to each adjustment stage at each adjustment stage. The information is transmitted to the operation control unit 3. The operation control unit 3 that has received the automatic adjustment operation designation information switches the magnetic recording / reproducing apparatus to the designated operation based on the automatic adjustment operation designation information.

Specific examples of the magnetic recording / reproducing apparatus which is adjusted and controlled by the adjustment control section in the state where the mode is shifted to the automatic adjustment mode are as follows. • A format transition operation control unit that controls switching between the formats A and B and the reproduction heads PB and R / P. • A position movement control unit that controls movement of the recording medium to a specified position. • A high speed that performs high-speed reproduction system adjustment control. Playback system adjustment control unitPrecision playback system adjustment control unit that precisely performs playback system adjustment controlRecording system adjustment control unit that performs recording system adjustment controlAdjustment end operation that performs operation control such as ejection of recording medium after adjustment is completed Control unit

[0007]

In such a conventional apparatus, since the automatic adjustment operation specifying means 2 itself is not operating in the normal operation mode, the automatic adjustment operation from the automatic adjustment operation specifying means 2 is not performed. The instruction is not transmitted to the operation control unit 3, but in the automatic adjustment mode, when the user operates the operation specifying unit 1, the operation instruction is transmitted to the operation control unit 3, and the operation control unit 3 As a result, the operation required for the automatic adjustment cannot be performed for No. 3, and a problem such as a defect in the adjustment result occurs.

For this reason, at present, the user must pay close attention to the operation in the automatic adjustment mode so as not to operate the operation specifying unit 1. According to the present invention, in the automatic adjustment mode, the operation of the magnetic recording / reproducing apparatus does not shift to the invalid operation specification by the operation specifying unit 1 or the operation setting by the automatic adjustment operation specifying unit 2 during the normal operation. An object is to provide an adjustment control device.

[0009]

According to a first aspect of the present invention, there is provided an automatic adjustment control device for a magnetic recording / reproducing apparatus which automatically adjusts a magnetic recording / reproducing apparatus having an adjustment control unit for controlling an adjusting operation according to a setting program. Automatic adjustment control device, wherein the automatic adjustment state detection means for detecting the automatic adjustment state whether the magnetic recording and reproducing device is in the process of automatic adjustment transition,
Indicates the automatic adjustment state information indicating the automatic adjustment state transmitted from the automatic adjustment state detection means, and the operation request transmitted from the operation specifying unit for performing the operation request of the magnetic recording / reproducing apparatus operated by the user in the normal operation mode. Operation determining means for determining whether or not to transmit the operation specifying information to an operation control unit for controlling the operation of the magnetic recording / reproducing apparatus based on the operation specifying information, and An operation request other than the specific operation request to be set is invalidated.

With this configuration, even if the user specifies an invalid operation in the automatic adjustment mode by operating the operation specifying unit during the automatic adjustment, the automatic adjustment state information received from the automatic adjustment state detecting means automatically sets the automatic operation. The operation determining means recognizing that the adjustment is in transition, determines that the operation designation information from the operation designation unit is an invalid operation instruction during the automatic adjustment transition, and controls the operation of the magnetic recording / reproducing apparatus. This prevents the magnetic recording / reproducing apparatus from shifting to the invalid operation during the automatic adjustment transition. For this reason, in the automatic adjustment mode, it is possible to eliminate a failure in adjustment that occurs when the user specifies an incorrect operation and the magnetic recording / reproducing apparatus does not perform an operation suitable for the automatic adjustment.

According to a second aspect of the present invention, there is provided an automatic adjustment control device for a magnetic recording / reproducing apparatus according to the first aspect, wherein the operation determining means determines that the operation specifying information a is information requesting a predetermined effective operation. Action designation information a only when judged
Is transmitted as the determined operation information c as it is.

Specifically, as set forth in claim 3 of the present invention, in claim 2, the information for requesting a predetermined valid operation is set as the information for requesting a forced stop. The user can designate the operation of forced termination and the like, so that even if a problem occurs in the adjustment due to any problem, the user can be forcedly terminated, so that it is possible to cope with an emergency of automatic adjustment.

Reference numeral 6 denotes an operation determining unit, which is an automatic adjustment state information d indicating the automatic adjustment state transmitted from the automatic adjustment state detection unit, and an operation designating unit for requesting an operation of the magnetic recording / reproducing apparatus by operating the user in the normal operation mode. 1 for receiving operation designation information a indicating an operation request to the magnetic recording / reproducing device transmitted from the device 1, and controlling the operation of the magnetic recording / reproducing device based on the automatic adjustment state information and the operation designation information. It is determined whether the operation designation information is transmitted to the unit.

The operation will be described with reference to the operation flowchart of the operation determining means 6 shown in FIG. First, the control operation of the magnetic recording / reproducing apparatus in the normal operation mode will be described. When the magnetic recording / reproducing apparatus is in the normal operation mode, the automatic adjustment state detection means 5 transmits to the operation determination means 6 automatic adjustment state information d indicating an automatic adjustment state indicating that the apparatus is not in the automatic adjustment transition state.

In step S1, the operation determining means 6
It is determined whether the detected information is the operation designation information a generated from the operation designation unit 1 or the automatic adjustment operation designation information b generated from the automatic adjustment operation designation unit 2. Here, considering a state in which the operation control unit 1 is operated in the normal operation mode,
It is determined that the information is the operation designation information a, and step S2 is executed.

In step S2, since the automatic adjustment state information d output from the automatic adjustment state detecting means 5 is not detected, it is determined that the normal operation mode is set, and step S3 is executed.

In step S3, it is determined that all the operation designation information a when the mode is not the automatic adjustment mode is valid, and the operation designation information a from the operation control unit 1 is directly used as the determined operation information c.

Performs judgment control.

If the operation request of the operation designation information a is a preset valid operation request such as forced termination, the operation discriminating means 6 indicates that the operation designation information a is a request for a valid operation. It is determined in step S7 that the operation control unit 3
The operation specification information a from the operation control unit 1 is transmitted as the determined operation information c as it is.

Then, the operation control unit 3, which has received the determined operation information c determined to be a valid operation, switches the magnetic recording / reproducing apparatus to the operation specified by the determined operation information c. In step S6, if the request is not a preset valid operation request, step S8 is executed to determine that the operation designation information a is invalid, and the operation designation information a is transmitted to the operation control unit 3. The operation specification information a is discarded without performing.

Therefore, since the operation specifying information a determined to be invalid is not transmitted to the operation control unit 3 for controlling the operation of the magnetic recording / reproducing apparatus, the magnetic recording / reproducing apparatus returns to the specified operation except in the case of forced stop. Does not migrate.

Also, in the automatic adjustment mode, the automatic adjustment operation designating means 2 transmits the automatic adjustment operation designation information b, which is an operation request to the magnetic recording / reproducing apparatus in the automatic adjustment mode, to the operation determining means 6. Then, through steps S1 and S4, it is determined that the automatic adjustment operation designation information b in the automatic adjustment mode is valid, and the operation controller 3 executes step S9 to control the operation of the magnetic recording / reproducing apparatus. The automatic adjustment required operation designation information b from the automatic adjustment operation setting means 2 is transmitted as determined operation information c as it is.

Then, the operation control unit 3 which has received the automatic adjustment required operation designation information b determined to be a valid operation switches the magnetic recording / reproducing apparatus to the operation designated by the determined operation information c.
As described above, the magnetic recording / reproducing apparatus can be controlled so that the operation does not shift to the invalid operation designation by the operation designation unit 1 during the automatic adjustment transition or the operation setting by the automatic adjustment operation designation unit 2 during the normal operation.
