DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage medium for storing a plurality of recording media such as a cassette tape which can be attached to and detached from a recording / reproducing apparatus. The present invention relates to an information recording / reproducing apparatus capable of reproducing information from an information recording / reproducing apparatus, and an operation test method for performing an operation test of such an information recording / reproducing apparatus.

[0002]

2. Description of the Related Art Conventionally, a plurality of recording media (for example, cassette tapes or disk-shaped recording media) which can be attached to and detached from a recording / reproducing apparatus are stored, and if necessary, the recording media are stored in the storage media. To record various information,
There is a system for reproducing recorded information. Such a system is called a library system or an autochanger or the like, but will be referred to as a library system in the following description.

Some library systems have a predetermined configuration, while others have a configuration that can be changed to some extent according to the user. As a library system that can change the configuration in this way, for example,
A recording / reproducing console having a recording / reproducing device for recording / reproducing information on / from a recording medium, a recording medium storing console having a plurality of storage sections each capable of storing a recording medium, and the like. Some consoles are provided with a plurality of consoles, and a library system of various scales and arrangements can be constructed by arbitrarily combining these consoles. Some recording / playback consoles have a plurality of storage sections each capable of storing a recording medium. Further, such a library system includes a transport device that transports a recording medium between an arbitrary storage unit in a recording medium storage console and a recording / reproducing device, and a control unit that controls the recording / reproducing device and the transport device. Have.

In this library system, various types of information can be recorded on a large number of recording media and information can be automatically reproduced from the recording media. Therefore, the library system is applied to a system that handles a large amount of information such as video data. In this case, significant labor savings can be achieved. In particular, when the library system is constructed as a configuration in which the configuration can be changed, it is possible to flexibly respond to changes in the situation, such as when the amount of information to be handled increases.

[0005]

However, since the library system having the above-described configuration is large in size as a whole, when the library system is delivered to a customer, the library system is divided into individual console blocks and transported to the site. Need to be assembled there. For this reason, for example, the assembled library system may have mechanical or electrical problems due to unevenness of the floor at the installation location or other causes, and an operation test after assembly and installation is essential. Further, in the library system having the above configuration, the console can be added or expanded or the configuration can be changed in accordance with an increase in the number of recording media to be handled.
It is necessary to perform an operation test after changing the system configuration.
In addition, a failure occurs in one of the library systems,
Even when this is repaired, an operation test is required.

The operation test of such a library system is usually performed by a specialized service person. Also, this operation test does not necessarily have to be performed for the entire system, for example,
In some cases, such as when a part of the configuration is changed or repaired, it is desired to test only the blocks related to the changed or repaired portion, or to test only some of the many functions. In order to respond to such a request, for example, a function capable of individually executing a plurality of types of operation tests is prepared in the system in advance, and a simple display device provided on a console of the library system by a service staff is provided. There is a method in which a desired operation test is performed by inputting a predetermined operation test number using the operation key and the operation key.

However, in the above method, the service technician remembers the operation test number and the contents of the operation test in association with each other, or selects a desired operation test number while referring to a manual or the like, and inputs this. Must. For this reason, when there are various types of operation tests, it is difficult for the service person to remember all of them, and it is inconvenient to select an operation test number while looking at the manual one by one.

[0008] Even if various types of operation test functions are prepared in advance by assuming a large number of cases, there are cases where those operation tests cannot properly cope with the initial assumptions. In some cases, such cases cannot be dealt with later due to omission or a change in the configuration of the library system. However, in the above method, the contents of each operation test are fixed and cannot be freely changed on site. For this reason, there is a case where it is necessary to give up the optimal operation test and perform the next best operation test. On the other hand, it is also possible to add a function for performing a new operation test by replacing or modifying the control board and the like of the library system. It cannot be performed without requesting the design or maintenance department of the car, and the service staff cannot immediately cope with the situation on site.

Further, in the above method, once the operation test is started by inputting the operation test number, the operation test is always started from the beginning, and the execution cannot be started halfway. Further, it is not possible to temporarily stop the operation test on the way or to restart from the place where the operation test is stopped. That is, there is no flexibility in executing or stopping the operation test, and it is not possible to select and execute only a part of one operation test sequence.

That is, in the above method, it is difficult to freely perform an optimal operation test in response to a change in the configuration of the library system or a change in the situation, and to freely start and stop the operation test. is there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide information that enables free and easy execution of an optimal operation test in response to a change in the system configuration or a change in the situation. An object of the present invention is to provide a recording / reproducing apparatus and an operation test method thereof. Another object of the present invention is to

As shown, a test menu is displayed in a pull-down manner under the item 93 of 'Test'. In the following description, “selection of an item” means left-clicking with a mouse unless otherwise specified. In addition, the term “click” may be used instead of the term “selection”, if necessary. Words shall be used.

From the above test menu, select 'Prog
When the item 94 “ram ′” is selected (step S1)
05; Y), the central processing control unit 46 displays an operation test program dialog box as shown in FIG. 11 (step S106). In the operation test program dialog box, an operation for performing an operation test of the cassette library 1 using an operation test program described in a shell script format that can be handled as a normal text file, and an operation test such as this Programs can be created and edited.

Here, the shell script format refers to the OS
(Operating system) A script format that can be executed by a command shell.
It is similar to the format used in S. In addition,
The command shell refers to an interpreter that interprets and executes a command input by a user, and the script refers to text (characters and character strings) describing a processing procedure.
That is, the shell script format refers to a format described using a shell script that is a character or a character string (text) representing an instruction (command) executed by a sequential interpretation method (interpretive method). As the OS, for example, Windows 95 (registered trademark of Microsoft Corporation) or the like can be used.

Such an operation test program in the form of a shell script can be created by a normal text editor in any other computer.

Here, the function of each section in the operation test program dialog box shown in FIG. 11 will be described. A toolbar 97 including various command buttons for handling the operation test program is provided in an upper area of the operation test program dialog box.

In an area occupying substantially the lower half of the operation test program dialog box, a command drop-down list box 105, a command execution button 107,
Command execution progress list box 106, end button 1
08 and a help button 109 are arranged. Of these, the command drop-down list box 105
Is used when only one control command is input to test a single operation in the cassette library 1. In the command drop-down list box 105, a command can be directly input from the keyboard of the input device 22 (FIG. 3), or an arbitrary command line displayed in the program text box 98 can be input by selecting with a mouse. ,further,
It is also possible to select and input from a command execution history list (not shown). The command execution button 107 is used to execute a command input in the command drop-down list box 105. The command execution progress list box 106 is an area for additionally displaying executed commands sequentially. The end button 108 is used to close this operation test program dialog box.

The help button 109 is used to display a help screen for explaining the function of each part in the operation test program dialog box and the contents of commands usable in the operation test program. As this help screen, for example, FIGS.
6 is shown. These help screens will be described later.

In the operation test program dialog box shown in FIG. 11, the number of executions of the operation test program (= the value of a reservation variable cycle described later) is displayed in the 'Cycle' column 110, and the 'BCR' column 111
In a, the number of barcode reading trials of a cassette by a barcode reader (not shown) of the cassette transporter 16 (= the value of a reservation variable bcrcnt described later) is displayed.
The R 'column 111b displays the number of successful barcode readings (= the sum of the values of the reservation variables bcrok1 to bcrok3, which will be described later), and the' Read Count 'columns 112a to 112b.
2c shows the number of readings until barcode reading succeeds (=
The values of the reservation variables bcrok1 to bcrok3 (to be described later) are displayed. Also, 'Default
The Line 'column 113 displays a numerical value used to specify a default console column number in a command that requires the console column to be specified. When the console column portion of the arguments of each command described later is omitted, the value of the 'Default Line' column 113 is automatically specified.

In the operation test program dialog box shown in FIG. 11, when the new creation button 97a on the toolbar 97 is selected (step S107; Y),
The central processing control unit 46 shifts to the edit mode in which the operation test program can be input, and displays the program input here in the program text box 98 (step S108).

FIG. 12 shows a state where an example of a simple operation test program is input. This example program uses the command 'carry' to transport a cassette.
5 shows an operation test in which cassettes are successively moved between storage sections of a predetermined cassette storage shelf. Control commands, control codes, variables, and the like used in this program will be described later.

When, for example, the mode switching button 103 is selected in the state shown in FIG. 12 (step S109), the central processing control unit 46 shifts to the execution mode as shown in FIG. 13 (step S110).

The operation and operation related to the execution and stop of the program will be described with reference to FIGS.

FIG. 13 shows the state when the program pointer is at the first line of the program in the execution mode. As shown in FIG.
Illuminates the line pointed to by the program pointer. At the left end of each program line, a program line number is displayed. Here, when the execution button 101 is selected (Step S111; Y in FIG. 9), the central processing control unit 46 starts executing the program (Step S11).
2) As shown in FIG. 14, the light-up display of the program line being executed is moved with the execution of the program. At this time, the command execution progress list box 10
6 displays the executed commands sequentially. here,
When the stop button 102 is selected, the central processing control unit 46
Stops the execution of the program and, as shown in FIG. 15, causes the next line (the seventh line in the illustrated example) following the last executed program line in the program text box 98 to be lighted up. At this time, the central processing control unit 46 sets the command execution progress list box 10
At 6, a message indicating that the program is being stopped is displayed together with the number of the stopped program line. Here, when the execution button 101 is selected again, the execution of the program is restarted from the line (the seventh line in the illustrated example) that has been lighted up.

When any line of the program displayed in the program text box 98 is clicked with the mouse before or when the execution of the program is stopped, the central processing control unit 46 lights up the line. . Here, when the execution button 101 is selected, the central processing control unit 46 starts the execution of the program from the program line displayed in the light-up display. For example, FIG.
As shown in FIG. 6, when the program line with the line number “12” is clicked and the execution button 101 is selected, the execution of the program starts from the line with the line number “12”.

As described above, the fact that execution can be started or stopped freely on a line-by-line basis of a program is not a program in a compile format, but an interpretive program that performs sequential interpretation on a line-by-line basis. Because it is a program of the form. In this case, the value of the program pointer is always held in a register (not shown) of the central processing control unit 46. During the execution of the program, the value of this register changes with the execution of the program. Then, the change of the register value stops. When the execution of the program is resumed, the value of the register changes again with the execution of the program. When the execution of the program is started from an arbitrary line, the value of the program pointer indicating the specified execution start line is set in the register, and the execution starts from there.

Returning to FIG. 8, the description will be continued. When the load button 97b of the toolbar 97 is selected in the operation test program dialog box of FIG. 11 (step S116; Y), the central processing control unit 46 displays a program load dialog box as shown in FIG.

Etc.) and other reserved variables line, console, row, colum
This is performed using n or the like, and details thereof will be described with reference to FIG. In step S10 in FIG. 27, the value 'XXXX
As a result of decoding of 0101F ′, it is found that the bin to be accessed is the bin at the upper left corner of the front of the console. Next, the central processing control unit 46 determines that “B” in step S11 of FIG.
A subroutine called IN put 'is called and executed, and cassette insertion / removal processing with respect to a target bin (in this case, the bin at the upper left corner on the front side) is performed (step S2 in FIG. 29).
06). Details of the cassette loading / unloading process in this case will be described with reference to FIG.

Next, in step S12 of FIG. 27, the central processing control unit 46 sets the variable dest indicating the bin number of the access target.
'XXXX01MMF' is acquired as the value of
207), and decode the actual value indicated by the acquired value “XXXX01MMF” of the variable dest (step S208 in FIG. 29). Here, as a result of the decoding, it is found that the bin to be accessed is the bin in the upper right corner of the front of the console. Next, the central processing control unit 46 calls and executes the above-described subroutine 'BIN put' in step S13 of FIG. 27, and performs a process of taking a cassette in and out of a target bin (here, the bin at the upper right corner on the front). (Step S20 in FIG. 29)
9).

Next, the central processing control unit 46 sets the variable dest indicating the bin number of the access target in step S14 of FIG.
'XXXXMM01F' is acquired as the value of
210), and decode the actual value indicated by the obtained value 'XXXXMM01F' of the variable dest (step S211 in FIG. 29). Here, as a result of the decoding, it is found that the bin to be accessed is the bin at the lower left corner of the front of the console. Next, in step S15 of FIG. 27, the central processing control unit 46 calls and executes the above-described subroutine "BIN put", and performs a process of taking a cassette in and out of a target bin (here, the bin at the lower left corner on the front). (Step S21 in FIG. 29)

Next, the central processing control unit 46 sets the variable dest indicating the bin number of the access target in step S16 of FIG.
'XXXXMMMMF' is obtained as the value of
213), and decode the actual value indicated by the acquired value “XXXXMMMMF” of the variable dest (Step S214 in FIG. 29). Here, as a result of the decoding, it is found that the bin to be accessed is the bin at the lower right corner of the front of the console. Next, the central processing control unit 46 calls and executes the above-described subroutine "BIN put" in step S17 in FIG. 27, and performs a process of inserting and removing a cassette with respect to a target bin (here, the bin at the lower right corner on the front). (Step S21 in FIG. 29)
5). This completes the operation test of sequentially accessing bins at the four corners of the cassette storage shelf on the front F side of one console to insert and remove cassettes.

Next, the processing of the blocks in steps S19 to S26 in FIG. 27 will be briefly described with reference to FIG. This processing block sequentially accesses bins at the four corners of the cassette storage shelf on the rear R side of each console to insert and remove cassettes, and is basically the same as the processing of each step in FIG. is there. That is, in steps S19 and S20 in FIG. 27, the bin at the upper left corner of the console is accessed to insert and remove the cassette, and in S21 and S22, the bin at the upper right corner of the console is accessed to insert and remove the cassette.
In steps S23 and S24, the user accesses the bin at the lower left corner of the back of the console to load and unload the cassette.
At 6, access the bin at the lower right corner of the back of the console to take out and insert cassettes. This completes the operation test of sequentially accessing bins at the four corners of the cassette storage shelf on the rear R side of one console to insert and remove cassettes.

Referring now to FIG. 31, steps S205, S208, S211, and S214 in FIG. 29 and steps S217, S220, S223, and S2 in FIG.
The contents of the bin number decoding process performed at 26 will be described. First, the central processing control unit 46 extracts the character string at the digit position (or area) representing the console column from the value of the variable dest (step S301 in FIG. 31). For example, the variable
If the value of dest is 'XXXX0101F', the leftmost two-digit character string 'XX' is extracted.

Next, the central processing control unit 46 checks whether the extracted character string is a numerical value, 'XX' or 'MM' (steps S302, S303, S305). As a result, when the extracted character string is a numerical value (Step S302; Y), the central processing control unit 46 sets the extracted numerical value as it is in the digit position representing the console column in the variable dest (Step S302). Step S307). When the extracted character string is "XX" (step S30).
2; N, step S303; Y), central processing control unit 46
Is the reserved variable li stored in the temporary storage memory 48, for example.
The current value of ne is referred to (step S304), and the reference value (fixed to “1” in this program example) is set to the digit position representing the console column in the variable dest (step S304).
307). When the extracted character string is “MM” (Step S302; N, Step S303; N, Step S305; Y), the central processing control unit 46 stores the character string in the system information file 49b of the hard disk device 49. The current value of the reserved variable maxline in the library configuration information is referred to (step S306), and the reference value (“3” in the example of FIG. 2) is set to the digit position representing the console column in the variable dest ( Step S307). here,
For example, if the extracted character string is 'XX',
The fixed value '1' of the reserved variable line is set as the value of this character string. Thus, the console row L1 has been designated. If the extracted character string is not a numerical value, any of 'XX' and 'MM' (step S3
02; N, step S303; N, step S305;
N), the central processing control unit 46 determines that the character string is invalid, and performs a predetermined error process (step S30).
8).

Next, the central processing control unit 46 extracts the character string at the next digit position in the variable dest (step S30).
9). Here, the character string 'X at the digit position (the third and fourth digits from the left) representing the console from the value' XXXX0101F 'of the variable dest
X 'is extracted. Since the decoding of the digit position (the 7th and 8th digits from the left) representing the bin row (column) has not been completed yet (step S310; N), the process returns to step S302 and returns to step S302 in the same manner as described above. The processing of S308 is performed.

That is, the central processing control unit 46 checks whether the extracted character string is a numerical value, 'XX' or 'MM' (steps S302, S303, S305).
If the extracted character string is a numerical value (step S30
2; Y), the extracted numerical value is set as it is in the digit position representing the console in the variable dest (step S).
307). When the extracted character string is 'XX' (step S302; N, step S303; Y),
The central processing control unit 46 refers to the current value of the reserved variable console stored in, for example, the temporary storage memory 48 (step S304), and stores the reference value (in this case, any one of '1' to '6') in the variable dest. Is set to the digit position representing the console (step S307). When the extracted character string is “MM” (Step S302; N, Step S303; N, Step S305; Y), the central processing control unit 46 stores the character string in the system information file 49b of the hard disk device 49. The current value of the variable maxconsole in the library configuration information is referred to (step S30).
6), the reference value (“6” in the case of the console row L1 in FIG. 2) is set to the digit position representing the console in the variable dest (step S307). For example, the extracted character string is “XX”, and the current value of the reserved variable “consol” is “2”.
, The numerical value '2' is set as the character string 'XX'. In this case, in the example of FIG. 2, so that the drive console 1D ₁₁ is specified. Note that the error processing when the extracted character string is neither a numerical value nor 'XX' or 'MM' is the same as described above.

Further, the central processing control unit 46 sets the variable dest
The character string at the next digit position in is extracted (step S3).
09). For example, when the value of the variable dest is “XXXX0101F”, the character string “01” at the digit position (the fifth or sixth digit from the left) representing the bin is extracted. At this point, since the decoding of the digit position (the seventh and eighth digits from the left) representing the bin row (column) has not been completed yet (step S310; N), the step S310 is performed.
Returning to step 302, steps S302 to S
308 is performed.

That is, the central processing control unit 46 checks whether the extracted character string is a numerical value, 'XX' or 'MM' (steps S302, S303 and S305).
If the extracted character string is a numerical value (step S30
2; Y), the extracted numerical value is set as it is in the digit position representing the bin stage in the variable dest (step S30)
7). When the extracted character string is “XX” (step S302; N, step S303; Y), the central processing control unit 46 sets the current value of the reserved variable row stored in the temporary storage memory 48, for example. Refer to (Step S30
4), the reference value (one of '1' to '5' in the example of FIG. 1) is set to the digit position indicating the bin stage in the variable dest (step S307). Also, if the extracted string is' M
If it is M '(step S302; N, step S303; N, step S305; Y), the central processing control unit 46 makes a reservation among the library configuration information stored in the system information file 49b of the hard disk device 49. Referring to the current value of the variable conrow (step S306),
The reference value (“5” in the example of FIG. 1) is set to the digit position representing the bin stage in the variable dest (step S307).
For example, when the extracted character string is a numerical value '01', this value is set as it is in the digit position indicating the bin stage of the variable dest. In this case, the top row of the console is designated. Note that the extracted character string is a numeric value,
Error processing when neither "XX" nor "MM" is performed is the same as above.

Furthermore, the central processing control unit 46 sets the variable dest
The character string at the next digit position in is extracted (step S3).
09). For example, when the value of the variable dest is “XXXX0101F”, the character string “01” at the digit position (the seventh and eighth digits from the left) representing the bin string (column) is extracted. At this point,
Since the decoding of the digit position representing the bin sequence has not been completed (step S310; N), the process returns to step S302, and the processes of steps S302 to S308 are performed in the same manner as described above.

That is, the central processing control unit 46 checks whether the extracted character string is a numerical value, 'XX' or 'MM' (steps S302, S303 and S305).
If the extracted character string is a numerical value (step S30
2; Y), the extracted numerical value is set as it is in the digit position representing the bin row in the variable dest (step S30)
7). When the extracted character string is “XX” (step S302; N, step S303; Y), the central processing control unit 46 updates the current value of the reserved variable column stored in the temporary storage memory 48, for example. Refer to (Step S3
04), the reference value (one of '1' to '18' in the example of FIG. 1) is set to the digit position representing the bin string in the variable dest (step S307). When the extracted character string is “MM” (Step S302; N, Step S303; N, Step S305; Y), the central processing control unit 46 stores the character string in the system information file 49b of the hard disk device 49. The current value of the reserved variable concol in the library configuration information is referred to (step S30).
6), the reference value (“18” in the example of FIG. 1) is set in the variable dest
Is set to the digit position representing the bin row (step S3).
07). For example, when the extracted character string is a numerical value '01', this value is set as it is in the digit position indicating the bin stage of the variable dest. In this case, the leftmost end of the bin is specified. Note that the extracted character string is a numerical value,
Error processing when neither "XX" nor "MM" is performed is the same as above.

Furthermore, the central processing control unit 46 sets the variable dest
The character string at the next digit position in is extracted (step S3).
09), since the decoding of the digit position representing the bin row has already been completed (step S310; Y), this bin number decoding process ends.

Next, the processing of the 'BIN put' subroutine of steps S32 to S41 in FIG. 27 will be described with reference to FIG. In this subroutine, first, the central processing control unit 46 determines in step S35 of FIG.
Referring to the cassette storage position database 49a, it is checked whether or not a cassette is in the bin to be accessed designated by the variable dest indicating the destination of the cassette (FIG. 3).
Two steps S401). As a result, when the cassette is not contained therein (step S401; N), the process jumps to step S38, in which the cassette of the bin specified by the variable source indicating the cassette moving source is transported to the bin specified by the variable dest. Issue a command for Specifically, first, a command for removing a cassette from the bin designated by the variable source indicating the cassette transfer source is issued (step S402 in FIG. 32), and then the extracted cassette is designated by the variable dest. A command for insertion into the access target bin is issued (step S403). afterwards,
Set the value of the current variable dest to the variable sour in preparation for the next command
It is set to ce (step S404).

On the other hand, if a cassette is in the bin to be accessed (step S401; Y), the central processing control unit 46 in step S36 takes out the cassette in the bin once and inserts it again. Issue a command for Specifically, first, a command for once removing the cassette is issued (step S40).
5) Next, a command for inserting the removed cassette into the same bin again is issued (step S406).

Thus, regardless of the state of the bin whether or not the cassette is in the bin to be accessed, the operation of inserting and removing the cassette with respect to the bin to be accessed is always executed.

In the subroutine program illustrated in FIG. 27, the reserved variable line is set to "1" in step S5, and only the console of the console row L1 is targeted. '
If the program is configured to sequentially increment from "3" to "3", an operation test can be performed on the consoles of all console rows L1 to L3.

As described above, according to the library system of the present embodiment, the library controller 2 as the control means of the cassette library 1 can operate the operation test program for performing the operation test of each part of the cassette library 1. Since such a program operation function is provided, a user such as a service person or a maintenance person can freely perform an operation test of the cassette library 1 using this function. Therefore, for the user,
It is not necessary to remember the operation test number in association with the contents of each operation test as in the related art, or to select the operation test number while looking at the manual one by one. Also, even if a function for performing a new operation test is to be added, there is no need to request the design or maintenance department of the library system manufacturer as in the past, and a service person immediately takes action on site. It is also possible.

By simply clicking on any step of the operation test program displayed in the program text box 98 in the dialog box with a mouse or the like, the execution of the program can be started or stopped from that step. For example, cassette library 1
If an operation test is performed after removing the defect when a part of the defect occurs, it is not necessary to execute the entire operation test program, and it is also possible to perform only the operation test of the defective part. is there. Further, for example, a series of operation steps of the cassette library 1 may be finely divided to sequentially confirm stoppage and restart, and the operation may be confirmed, or only an operation test of a specific portion may be repeatedly performed to confirm reliability. Therefore, the operation test can be freely performed.

Further, in the present embodiment, the operation test program can be described in the form of a shell script. Therefore, anyone who has a certain basic knowledge of programs used in UNIX or the like has special knowledge of programming.

Also, the operation test of the cassette library 1 can be easily performed by easily learning how to program and handle the operation test program.

In this embodiment, when the system is started, the library configuration information is fetched from the cassette library 1 and stored in the system information file 49b of the hard disk drive 49, and all the cassettes stored in the cassette library 1 are stored. The storage position information is registered in the cassette storage position database 49a of the hard disk drive 49, and the library configuration information and the storage position information are appropriately referred to and taken into the operation test program. Even if the cassette is expanded or changed, or the cassette storage position in the cassette library 1 changes, an operation test having similar contents can be executed without changing the operation test program itself. That is,
Since a change in the configuration or status of the cassette library 1 can be executed after reflecting the change in the command interpretation of the operation test program, it is not affected by an expansion or change of the system configuration, a change in the system status, or the like. Therefore, 1
It is also possible to comprehensively perform operation tests of cassette libraries having various configurations by using one operation test program as it is.
