DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk data recording apparatus, and more particularly to an optical disk data recording apparatus for recording image data on a compact disk (CD) standard optical disk and a method thereof.

[0002]

2. Description of the Related Art Sony Philips 'compact disc standard (Orange Book standard) or Sony Philips' CD-ROM standard (Yellow Book standard) is conventionally based on pre-master press or one-time prerecording. However, there is only a one-time recording type in which a session is recorded at a time even though there are some differences in the steps. With the subsequent development of technology, write-once or re-recordable types of writable disks have been put to use. These conventional so-called one-time ROM discs are recorded by a software supplier and shipped under strict quality control. Therefore, it was good to say that the disc was never scratched from the beginning of use.

[0003]

However, in the case of a post-write type photo CD, if there is an empty area in the disc once recorded, or if the recorded data is to be erased and re-recorded, it will not reach the user's hand. May be re-recorded on a burned disc. Recording of image data is generally done by a specialized laboratory on CD
When used discs such as used discs are severely stained, scratched, or otherwise damaged during the process of reproduction, storage, transportation, etc. Can occur. Also, data recorded on a failed disk may become unreproducible in the future. However, since conventional CD writers are designed with only one-time recording compact discs in mind, new data must be added to the disc under the above-mentioned adverse conditions without damaging the data already recorded on the disc. It is difficult.

When recording on a compact disk having such bad conditions using a conventional CD writer,
A tracking error may occur, destroying not only a mistake in recording new data but also old data that has already been recorded. Also, even if the old data is not destroyed, it will be recorded on the damaged disk,
A disk containing data with a high data error rate is given to the user. It should be noted that data already recorded on the scratched disk may be unreproducible at some point in the future, and requires some care.

An object of the present invention is to provide an optical disk data recording apparatus capable of recording data already recorded on an optical disk together with new data, and a recording method thereof.

[0006]

According to the present invention, there is provided a data recording apparatus for an optical disk for recording image data on a write-once optical disk of the compact disk standard in a postscript manner,
Reproducing means for reading out the first image data recorded on the first optical disc; input means for inputting the second image data; recording means for recording the image data on the second optical disc; Controlling means and recording means,
There is provided control means for causing the reproducing means to read out the first image data from the first optical disc and for recording the first and second image data on the second disc by the recording means.

[0007]

According to the present invention, when post-recording image data on a write-once optical disc of the compact disc standard, the first image data recorded on the first optical disc is read and the second image data is read. Prepare these first
And the second image data is recorded on the second disk as independent sessions or integrated into a single session.

For example, if it is determined that additional recording is impossible due to a failure in the first optical disk, the old data recorded on the failed disk and the new data to be additionally recorded are recorded on the second disk. In the recording, the old data and the new data may be recorded as separate sessions, or the old data and the new data may be reorganized into one session, and the data after the organization may be recorded.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a data recording apparatus for an optical disk according to the present invention; FIG.
Referring to FIG. 1, an embodiment of an optical disc data recording apparatus basically includes, for example, a compact disc (CD) 26 on which image data received from a customer is recorded, for example, a scanner.
A device that records a new image signal obtained from an image data source such as 16 and / or the hard disk 12 in a postscript manner. However, the apparatus of this embodiment further inspects the state of the recording surface of the compact disc 26, and if there is no obstacle to the additional recording of data, new image data is added thereto,
If there is a failure, the image data is read from the compact disk 26 and recorded on the new compact disk 36 together with the new image data. At this time, the apparatus of the present embodiment can organize and record both the new and old image data in a single session, or can record them in separate sessions. This apparatus is installed in a laboratory of a photo CD software supplier, for example.

In order to realize this function, the present apparatus has a central processing unit 10, and the central processing unit 10 is at the center of a system that controls the operation of the entire system. Central processing unit
10 includes a scanner 16, a reproducing / recording device 20, and a recording device.
External devices such as 30 are interfaced via small computer system interface (SCSI) connection lines 82, 84 and 86, respectively. The central processing unit 10 also has
Display device 14 such as CRT, hard disk (HD) 1
2.Peripheral devices such as the operation device 18 are connected, and the central processing unit
It has a function to assist the operation of 10. Hard disk 12
This is a storage device for storing a program for operating this system, image data, and the like. These peripherals and central processing unit 10 are advantageously constituted by commercially available personal computer systems.

A compact disk (CD) 26 is removably loaded in the reproducing / recording device 20, and image data recorded on the compact disk (CD) 26 is read and sent to the central processing unit 10,
This is a device for recording another image data sent from the central processing unit 10 on the compact disk 26. Playback / recording device 20
Also, before recording new image data on the disk 26, it has a function of inspecting the recording surface of the disk 26 for any obstruction that may interfere with recording or reproduction, such as dirt and scratches. This inspection is performed based on whether or not the tracking property of the disk 26 due to the pre-groove is good, the amount of reflected light is reduced, and a protrusion in the tracking signal is detected. Details regarding this are described in the patent application “Apparatus and method for inspecting optical disks” by the same applicant as the present application.

The recording device 30 has another compact disc 36.
Is a device that is detachably loaded and records image data sent from the central processing unit 10 on the compact disk 36. The recording device 30 is also provided in addition to the reproduction / recording device 20 because when the above-described failure is detected in the compact disc 26 to which new image data is to be added, a new disc 36 is added.
This is to play the role of recording the image data to the printer.

As the compact discs 26 and 36, for example, write-once compact discs of the so-called Photo CD standard by Sony Philips are advantageously applied. However, the present embodiment is not limited to this, and may be, for example, a write-once or re-recordable optical disk, and may be either a one-time recording type or a so-called re-recording type that can be erased and reused. In this embodiment, one of the two disks is a disk brought in by a customer, and the other disk 36 is a so-called virgin disk on which no data is recorded. The recorded compact disc 26 is brought into the laboratory by a customer together with, for example, a color negative film (not shown) carrying an image to be added thereto. Therefore, in many cases, the disk 26 already has image data recorded thereon. In the present embodiment, the other disk 36 is basically a virgin disk in which data is not recorded in the entire recording area.

The scanner 16 is, for example, an image reading device that reads a color image recorded on the above-mentioned color negative film at a high resolution and sends an image signal corresponding thereto to the central processing unit 10. In the present system, image data read from this negative film is recorded on the compact disk 26 or 36.

The central processing unit 10 includes a control operation unit 102 for performing operations and control, a temporary storage memory unit (RAM) 104 for temporarily storing various data necessary for operating the present apparatus, and a compression / decompression / decompression / decompression / decompression of image data. An image processing unit 106 that performs editing and the like;
And input / output for exchanging signals with external and peripheral devices
(I / O) units 108 are connected to each other by connection lines 112 as shown in the figure. The connection line unit 112 is a bus system for transmitting data and control signals between units in the device 10.

The control operation section 102 is a functional section for controlling the operation of the entire apparatus. Its function is basically to record / reproduce image data read by the scanner 16, for example.
In this case, the recording / reproducing apparatus 20 inspects the condition of the recording surface of the compact disc 26, and if there is a failure, the recording / reproducing apparatus 20 reads the image data from the compact disc 26. hand,
This is stored in the recording device 30 together with the image data from the scanner 16.
Controls the recording on the compact disc 36 as a single session or separate sessions. Control operation unit 102
Further, it performs expansion / compression, encoding / decoding of image data, and conversion processing to a recording format of the compact disk standard. The temporary storage memory unit 104 includes a control operation unit
102 and a buffer memory in data transfer with an external device or a peripheral device. The image processing unit 106 is a functional unit that performs image data processing, for example, image synthesis, editing / organization, and repair.
These processes are performed under the control of the control operation unit 102.

The display device 14 is a device for visually displaying the state of the system and the image to be processed, and the operation device 18 is an input device for inputting instructions and data of an operator. The operating device 18 includes an instruction for the operator to read a negative film image by the scanner 16, an instruction and conditions for image processing, an instruction for inspecting the state of the compact disc 26, a reproducing / recording device 20 or a recording device. The key 30 is used to input various instructions to the system, such as an instruction to record image data on the disk 26 or 36 by the 30 and whether to integrate new and old image data into a single session, which will be described later.

In the operating state, the negative film (not shown) brought into the laboratory is set on the scanner 16, and the compact disk 26 brought with it is set on the reproducing / recording device 20. Then, the operator designates a desired frame on the negative film by the operation device 18 and instructs reading of the image. In response, the central processing unit 10 controls the scanner 16 to read the image carried by the film by the scanner 16 (FIG. 4, 202).
Image data representing the read image is sent to the central processing unit 10 via the connection line 82. The sent image data is
The temporary storage memory unit 104 via the interface of the O unit 108
Is stored (204).

At the same time, the central processing unit 10 causes the display device 14 to display the same image data. The operator has a display device
Looking at the display image 14, if there is an image defect due to improper exposure of the negative film or the like, an instruction is given for color correction and gradation correction as necessary. In response to this, the image processing unit 106 refines the image (206), and the control operation unit 102 compression-encodes the resulting image data and converts it into a recording format conforming to the compact disc standard. The image data on which these processes have been completed are transmitted to the optical compact disc 26 by the reproducing / recording device 20.
And, if necessary, also on the hard disk 12.

The central processing unit 10 includes a reproducing / recording device.
20 is instructed to record image data (208). In response to this, the reproducing / recording device 20 performs good tracking, reflected light quantity, and protrusion detection of the tracking signal for the recording surface of the disk 26, particularly for the unrecorded area thereof,
The disk 26 is inspected for damage such as scratches and dirt that may interfere with recording or reproduction (210). If there is no abnormality in the inspected disk 26 by the inspection 210 (FIG. 5, 212),
The central processing unit 10 sends the refined image data, that is, the data of the image read by the scanner 16 in this example, to the reproducing / recording device 20, and the latter 20 records this in an unrecorded area of the disk 26 (214).

However, the inspection 210 checks the disk 26 to be inspected.
If no abnormality is detected, new image data is not recorded on the inspected disk 26, but is recorded on the virgin disk 36 by another recording device 30. In this case, not only the new image data is simply recorded on the virgin disk 36, but also the image data recorded on the inspected disk 26, that is, the old data, is recorded on the virgin disk 36. This is because if there is an abnormality in the disk 26 to be inspected,
This is because there is a risk that the image data recorded in 26 may become unreproducible in the future.

More specifically, when it is determined that the disk 26 to be inspected has an abnormality, the central processing unit 10
The instruction to read the old data recorded on the inspection target disk 26 is given. The reproduction / recording device 20 reads the data recorded on the old disk 26 in response to the instruction (216).
. The read image data is transferred to the central processing unit 10 via the connection line 84. The central processing unit 10 stores the transferred image data in the temporary storage memory unit 104 (218), transmits it to the recording device 30, and records it on the virgin disk 36.

In this embodiment, two types of recording modes can be selectively used. One is a mode in which old data and new data are recorded as separate sessions, and the other is a mode in which both new and old data are integrated and recorded in a single session. The integration of new and old data is particularly effective when there is a high degree of relevance between the two image data, for example, and it is more convenient to unify the sessions for later management, playback use, and the like.

When an instruction to record new and old image data in separate sessions is input by the operating device 18, (22)
0), the central processing unit 10 forms one session with the old data stored in the temporary storage memory unit 104 and sends it to the recording device 30, and then another new data in the temporary storage memory unit 104 One session is formed and transferred to the recording device 30. The recording device 30 records this on the new disk 36 (2
twenty four) . The recording device 30 stores these data in a new disc 36
(226).

FIG. 2 shows the state of the recording area of the disk 36 on which the two sessions are recorded. In this example, a lead-in area 41 of one session, a program area 42 including old image data, and a lead-out area 43 are formed in this order from the center of the disc 36 to the outside, and another one of the sessions , A new image data program area 46, and a lead-out area 47 are formed. Outside this, an unrecorded area 49 remains in this example.

When it is desired to integrate new and old data, the operator inputs a command for integration using the operating device 18. In response to this command, the control operation unit 102 of the central processing unit 10 integrates the old data and the new data already stored in the temporary storage memory unit 104 into a single session (222). In this knitting process, the image frames may be rearranged, or the new and old images may be simply stored in one session.
When rearranging the images, a reduced image such as an index image is displayed on the display device 14, and the operator sets the order of the images using the operation device 18 while viewing the monitor image. When session integration is performed, the control operation unit 102 regenerates data of the lead-in area and the lead-out area regardless of whether or not the images are rearranged. This is because related data changes as the number of image data in the session, the recording area, and the like change.

FIG. 3 shows the state of the recording area on the disk 36 after recording as a single session. The lead-in area 51, the program area 52, the lead-out area 53 and the unrecorded area 56 are located from the center of the disc 36 in FIG.
Becomes In this way, both the new and old image data are written on the virgin compact disc 36 having no obstacle, and the program area 52 is formed. This disc 36 is handed over to the customer together with the negative film and the old disc 26 that have been kept.

In the above embodiment, the integration of the old and new image data into a single session and the organization into separate sessions are configured to be selectable by the operating device 18. However, the invention is not necessarily limited to this,
A system that can only be integrated into a single session or a system that can only be organized into separate sessions may be configured. In this embodiment, image processing of new data is performed.
It was configured to perform 206 and then perform inspection 210 on disk 26. However, the invention is not limited to this order. For example, a configuration may be adopted in which an unrecorded area of the disk 26 is inspected and then the film image is read by the scanner 16.

[0029]

As described above, according to the present invention, for example, by reading out data from a faulty disk and recording new data on the new disk,
Avoid the risk of destroying existing data. Further, if it is possible to arbitrarily select to organize the new and old data recorded on the new disc into single or separate sessions, it is more advantageous in the reproduction use and management of the subsequent data.
