Abstract

PURPOSE:To improve the throughput of an information recording processing without deteriorating the reliability of recorded information by selecting whether to discriminate the reliability of recorded information or not. CONSTITUTION:When a registration processing terminates, a display device 19 is set to a display state. When 'Read after write check' is designated, for example, in such a state, 'a read after write check' is performed to picture information written in an optical disk 15 in accordance with information of a saved write command which is immediately before and the reliability of write information is checked. Thus, an operator can designate whether 'the read after write check' is performed or not at the time of registering picture information. Thus, the through put can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device that is capable of storing image information on, for example, an optical disk and searching and outputting stored image information.

(Prior Art) In this type of information processing device, when information is recorded on an optical disk, a read-after-write check is always performed to read the recorded information and determine the reliability of the recorded information. ing.

Although this improves the reliability of the recorded information, it takes time to check the post-lead meeting.
Throughput (information processing capacity per unit time) was reduced.

(Problem to be solved by the invention) This invention solves the problem in that when recording information, it is necessary to
This method solves the problem of throughput reduction by performing a write check operation, and its purpose is to create an information processing device that can prevent throughput reduction when recording information. This is what we are trying to provide.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides a recording means for recording information on a recording medium and determining the reliability of the information recorded on the recording medium. a determining means; a selecting means for selecting whether or not the determining means should determine the reliability of the information recorded on the recording medium when the recording means records the information on the recording medium; and instruction means for instructing discrimination of information recorded on the recording medium.

(Operation) That is, in the case of recording information on a recording medium by the recording means, the present invention makes it possible to select whether or not to perform the reliability determination of the recorded information by the selection means, and when the determination by the determination means is not selected, By allowing the instruction means to separately instruct only the determination, it is possible to improve the throughput of information recording processing without reducing the reliability of recorded information.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIG. 1, a bus 12 is connected to a CPU 11. This bus 12 includes a keyboard 13 and a memory 14.
, an optical disk device 15, a magnetic disk device 16, a scanner device 17, a page memory 18, a display device 19, and a printer device 2o are connected.

The CPUI 1 controls the entire device.

The keyboard 13 is used to enter various information such as command information manually. The memory 14 stores programs and the like necessary for the operation of the CPUI 1.

Further, the optical disk device 15 is loaded with an optical disk (not shown), and this optical disk includes the scanner device 1.
7 and stored in the page memory 18 are stored. The magnetic disk device 1
6 stores search information for searching image information stored in the optical disk device 15, write commands, and the like. The scanner device 17 exposes and scans an image of a document set on a document table (not shown).
It generates electrical signals corresponding to the original image. The page memory 18 stores image information read from the scanner device 17 and image information read from the optical disk device 15. The display device 19
Displays various processing information in response to instructions from the CPU 1, and displays image information stored in the page memory 18. The printer device 20 prints out information displayed on the display device 19.

FIG. 2 shows the structure of the write (WRITE) command. This write command is
code (OPC), start block (STB) that indicates the writing start block of the optical disc, information length (L) that indicates the length of the written information, presence or absence of read after write check (RAW), presence or absence of alternative processing (A LT), etc.

In the above configuration, the operation when writing image information to the optical disk device 15 will be explained.

The screen of the display device 19 normally displays information as shown in FIG. 3(a). When "registration" is designated in this display state, a display is displayed on the display device 19, as shown in FIG. 19(b), to designate whether or not to perform a read-after-write check. In this display state, after specifying the read-after-write check as "enabled", setting the required original in the scanner device 17 and setting predetermined search information, etc., the registration operation is started.

In this registration operation, image information of the document is read by the scanner device 17, and this read image information is stored in the page memory 18. The image information stored in this page memory 18 is written to the optical disk device 15. ``In this write operation, the write command is generated.

That is, the start block (S
The write start block of the optical disc is set in TB), and the length of the write information is set in information length (L). Furthermore, when the read-after-write check is specified as "enabled" as described above, '1m' is set in "RAW".

When the write command is generated, first, it is determined whether a read-after-write check is to be performed (step 5TI). As a result, read-after-write
If the check is "YES", a write operation is started as in the conventional case (step 5T2). This write operation is performed in units of one block set on the optical disc. That is, one block of image information read from the page memory 18 is transferred to the optical disk device 15 and written therein. When this write operation is completed, a read-after-write check is performed (step 5T3). When this read-after-write check is completed, it is determined whether or not the write operation of all image information has been completed based on the length (L) set in the write command (step 5T4). As a result, if the write operation has not been completed, the read operation is performed as described above.
An after-write competition check will be held. Therefore, in this write operation, a write operation read-after-write check operation is performed as shown in FIG. 5(a).

In addition, in the display state shown in FIG. 3(b), the lead
If the after-write check is set to ``no'', it is determined in step STI that the check during the read contention after-write is ``no''. In this case, the write command is saved (step 5T5),
A write operation is performed (step 5T6). This writing operation is also performed in units of one block on the optical disk, as described above. Then, each time the write operation for one block is completed, it is determined whether or not the write operation for all information has been completed (step 5T7), and if it has not been completed, the next information write operation is performed. Further, if it is determined that writing of all information has been completed, execution of the write command is ended. By not performing a read-after-write check in this manner, write operations are performed continuously as shown in FIG. 5(b).

On the other hand, when the registration process is completed, the display device 19 is brought into the display state shown in FIG. 3(a). In this state, if you specify, for example, "read contention after write check" (step 5T8), the image information written on the optical disk will be read after read according to the information of the last write command that has been saved. A write check is performed (step 5T9) to check the reliability of the written information.

According to the above embodiment, the operator can specify whether or not to perform a read-after-write check when registering image information. Therefore, when the read-after-write check is set to "no", only write operations can be performed continuously, thereby improving throughput.

Moreover, after the registration operation is completed, only read/after write/check can be specified independently.
This allows you to check the reliability of written information.

Next, a second embodiment of the present invention will be described using FIGS. 6 to 8.

In the above embodiment, the operator specifies whether or not to perform a read-after-write check, but in this embodiment, the CPU automatically controls whether or not to perform a read-after-write check. What I did
It is.

FIG. 6 shows the structure of the write command in this embodiment. This write command is used for operation, code (OPC), start ψ block (STB)
, information length (L), presence or absence of alternative processing (ALT), etc.

Information as shown in FIG. 7 is normally displayed on the screen of the display device 19. In this display state, "Register"
When the user specifies , sets a document on the KisYana device 17 as in the above embodiment, and inputs the required search information, the registration operation starts. In this registration operation, the write command is generated.

That is, the start block (S
The write start block of the optical disc is set in TB), and the length of the write information is set in information length (L).

When the write command is generated, first, it is determined whether the information length is longer than a predetermined value (for example, the length of several blocks of an optical disc) (step 5TII in FIG. 8).

As a result, if the length is shorter than the predetermined value, a write operation is started (step 5T12). This write operation is performed in units of one block set on the optical disc. That is, one block of image information read from the page memory 18 is transferred to the optical disk device 15 and written therein. Once this write operation is complete, the read-after-write
A check is performed (step 5T13). When this read-after-write check is completed, it is determined whether the writing operation of all image information has been completed (step 5).
T14), if not finished, do as above,
Each time a write operation is performed, the read-after-write
A check is performed.

On the other hand, in step 5T11, if the information length is longer than the predetermined value, "FLAG" is set to "1" and the write command is saved (step 5T11).
15), a write operation is performed (step 5T16)
. This write operation is also performed in units of one block on the optical disk, similarly to the above. Then, each time the write operation for one block is completed, it is determined whether the write operation for all information has been completed (step 5T17), and if not, the next information write operation is performed. Further, if it is determined that writing of all information has been completed, execution of the write command is ended.

On the other hand, the CPU II, for example, at every predetermined timing “FL”
AG" status is determined (step 5T18). As a result, if "FLAG" is '1", the image information written to the optical disc based on the last saved write command is determined. In contrast, lead/after/
A write check is performed (step 5T19).

In the above embodiment as well, the throughput can be improved as in the above embodiment.

Moreover, in the case of this embodiment, it is automatically determined whether or not to perform a read-after-write check without operator intervention, and if a read-after-write check is not performed, a write operation is performed. After the read-after-write check is completed, a read-after-write check is automatically performed at a predetermined time. Therefore, the operation is easy and the layer throughput can be improved.

Note that this invention is not limited to the above embodiments,
Of course, various modifications can be made without departing from the gist of the invention.

[Effects of the Invention] As described in detail above, according to the present invention, when information is recorded on a recording medium by the recording means, it is possible to select whether or not to perform reliability determination of the recorded information by the selection means, To provide an information processing device that can improve the throughput of information recording processing without reducing the reliability of recorded information by separately instructing only discrimination using an instruction means when discrimination by a discrimination means is not selected. can.
