Description

  The present invention relates to a recording apparatus that includes a first drive device that records data on a first medium and a second drive device that records data on a second medium.

  Conventionally, various optical disk recorders with hard disk drives have been devised. An optical disc recorder with HDD includes a buffer memory for temporarily storing data input from an input source, an optical disc drive for recording data in the buffer memory on an optical disc, and data in the buffer memory as a hard disk (hereinafter referred to as “HD”). A hard disk drive (hereinafter referred to as “HDD”). The optical disk is, for example, a CD or a DVD.

As a method of using such an optical disc recorder with HDD, first, content such as a TV program is recorded on HD. After the recording is completed, the user copies the content from the HD to the optical disc for the purpose of backing up the content.
On the other hand, Patent Document 1 proposes an information recording apparatus.
JP 2004-118986 A

However, this is a problem if the user has already considered recording content on both HD and optical disc media when recording content on the HD. More specifically, even in this case, the user has to take a step of dubbing to the optical disc after recording the content on the HD.
Therefore, the user has to wait between the start of recording content on the HD and the end of dubbing on the optical disc. Further, the user has to instruct dubbing to the optical disc after instructing to record the content on the HD, which is troublesome.
Accordingly, when the user thinks as described above, the conventional HDD-equipped optical disk recorder has a problem that the user is not easy to use.

  An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a recording apparatus that improves the usability of a user by performing storage management of a buffer memory.

  The recording apparatus of the present invention has the following configuration in order to solve the above problems.

(1) a first drive device for recording data on a first medium;
A recording device comprising: a second drive device for recording data on a second medium;
A first buffer memory for temporarily storing data input from an input source;
When recording of data to both the first medium and the second medium is instructed, the data currently stored in the first buffer memory is transferred to the first drive device and the second drive. Supply means for supplying to each of the devices,
The supply means updates the contents of the first buffer memory with data newly input from the input source after the supply to both the drive devices is completed.

In this configuration, the recording device is, for example, a DVD recorder with an HDD. The first medium is, for example, an optical disk, HD, or semiconductor memory. The second medium is also an optical disk, HD, or semiconductor memory, for example.
In this configuration, it is assumed that the user has already considered recording the content on both the first medium and the second medium when recording the content on the first medium. Yes.
In such a scene, the user gives an instruction to record data on both the first medium and the second medium. Then, the supply means performs storage management of the buffer memory and operates as follows. The supply means supplies the data currently stored in the buffer memory to the first drive device and the second drive device, respectively. The supply means updates the contents of the buffer memory with the data newly input from the input source after the supply to both drive devices is completed. This supply and update is repeated until content recording is completed.
As a result, when recording content on both HD and optical disc media is already considered at the start of recording content on HD, the user dubbs the content onto the optical disc after recording the content on HD. Don't take steps.
In other words, since the contents are simultaneously recorded on both the HD media and the optical disc, it is possible to shorten the time for which the user waits. Moreover, since the user only has to instruct recording of the content once, it is possible to save time and effort. Therefore, user convenience can be improved.

(2) The first drive device records the data stored in the second buffer memory in the first medium, the second buffer memory temporarily storing the data supplied from the supply means Recording means for
The supply means temporarily stops supplying data to the first drive device before the second buffer memory overflows.

If the supply means continues to supply data without considering the recording speed of the recording means, a buffer overflow occurs in the second buffer memory.
In this configuration, the supply means temporarily stops the supply of recording data to the optical disc drive before the second buffer memory overflows.
Thereby, the buffer overflow of the second buffer memory can be prevented.
Note that the supply means resumes data supply to the optical disk drive after temporarily waiting.

(3) The first medium is an optical disk,
The first drive device is an optical disc drive device that irradiates the optical disc with laser light from a pickup head and records data on the optical disc,
The supply means supplies data to the first drive device before the second buffer memory underflows during data recording.

The optical disk drive device interrupts the recording operation when the second buffer memory overflows. As a result, the optical disk drive device leaves a mark due to the laser beam on the optical disk and creates a joint.
In this configuration, data is stored in the second buffer memory so that the recording operation is not interrupted during recording on the optical disk.
Thereby, it can prevent that the trace by a laser beam remains and a joint is made on an optical disk.

  According to the present invention, user convenience can be improved.

  Hereinafter, a DVD recorder with an HDD according to an embodiment of the present invention will be described.

FIG. 1 is a block diagram showing a configuration of a DVD recorder with HDD according to an embodiment of the present invention. The DVD recorder 1 with HDD records, for example, an optical disc drive 200 that records data (such as a TV program) on an optical disc 100 manufactured in conformity with the DVD (Digital Versatile Disk) standard, and a large capacity data in the built-in HD 300A. An HDD (Hard Disk Drive) 300, and a data processor 400 including a buffer memory 400A for temporarily storing data input from an input source.
In this embodiment, the first medium is the optical disc 100 and the second medium is the HD 300A, but other media may be used in the implementation. Another medium is, for example, a semiconductor memory.

  Further, the DVD recorder 1 with HDD controls the operations of the AV input terminal 101, the tuner 102, the encoder unit 103, the timer microcomputer 109, the operation unit 110, the memory 111, the display unit 108, and each part of the apparatus main body. An MPU 105.

  The AV input terminal 101 inputs a video signal, an audio signal or the like to be recorded from the outside of the DVD recorder 1 with HDD and outputs it to the connected encoder unit 103. For example, the Internet is connected to the outside.

The tuner 102 is connected to an antenna (not shown) that receives a television broadcast signal distributed from, for example, a broadcaster. Then, tuner 102 extracts the TV broadcast signal of the selected channel from the TV broadcast signal received by the antenna, and outputs it to encoder section 103.
The AV input terminal 101 or the tuner 102 corresponds to the “input source” of the present invention.

  The encoder unit 103 includes a buffer memory (not shown).

The encoder unit 103 temporarily stores the video signal and audio signal input from the AV input terminal 101 in a buffer memory (for example, in MPEG2). The encoder unit 103 sequentially reads, encodes, and compresses data in the buffer memory. The encoder unit 103 stores the compressed data as recording data in the buffer memory 400A of the data processor 400.
In addition, the encoder unit 103 separates the video signal and the audio signal from the television broadcast signal input from the tuner 102. The encoder unit 103 temporarily stores these signals in the buffer memory. The encoder unit 103 sequentially reads, encodes, and compresses data in the buffer memory. The encoder unit 103 stores the compressed data as recording data in the buffer memory 400A of the data processor 400.

  The data processor 400 includes a buffer memory 400A that temporarily stores recording data output from the encoder unit 103. The data processor 400 supplies the recording data currently stored in the buffer memory 400A to at least one of the optical disc drive 200 and the HDD 300 according to the control of the MPU 105.

Further, the data processor 400 supplies the data read from the optical disc drive 200 to the HDD 300 and supplies the data read from the HDD 300 to the optical disc drive 200 according to the control of the MPU 105.
The data processor 400 and the MPU 105 correspond to the “supplying unit” of the present invention.

  The optical disc drive 200 irradiates the optical disc 100 with laser light from the pickup head under the control of the MPU 105 and the buffer memory 200A for temporarily storing the recording data supplied from the data processor 400, and the optical disc 100 is recorded with the recording data in the buffer memory 200A. And a recording unit 200B for recording. The optical disc 100 is a recordable optical disc such as a recordable DVD-R or a rewritable DVD-RAM.

The recording unit 200B corresponds to the “recording unit” of the present invention.
In this embodiment, the optical disc 100 is a DVD, but a CD may be used in the implementation.

  The HDD 300 records the supplied recording data on the HD 300A according to the control of the MPU 105.

On the other hand, a timer microcomputer 109 is connected to the MPU 105.
The timer microcomputer 109 has a timer circuit (clock unit) 109A used for time management of the DVD recorder 1 with HDD. The timer microcomputer 109 instructs the MPU 105 to start recording when the recording reservation start time comes. In addition, the timer microcomputer 109 instructs the MPU 105 to end recording when the recording reservation end time comes.

  The timer microcomputer 109 is connected to an operation unit 110 that receives an operation (instruction) from a user. The MPU 105 is connected to a display unit 108 that displays an operation state of the DVD recorder 1 with HDD and a memory 111 such as an EEPROM.

The memory 111 stores a control program.
The MPU 105 controls a data recording operation, a reading operation, a deleting operation, a display operation of the display unit 108, and the like on the HD 300A and the optical disc 100 based on a control program stored in the memory 111.

  In addition, the MPU 105 acquires control information of the optical disc 100 or the HD 300A from the optical disc drive 200 or the HDD 300. Then, the MPU 105 monitors the remaining capacity of the HD 300A built in the HDD 300 and the optical disc 100 set in the optical disc drive 200 from the acquired control information and the like.

  The operation unit 110 has a recording key for recording a TV program and the like, a double recording key for receiving data recording on both the optical disc 100 and the HD 300A, and other operation keys. Then, by these key operations, the user performs recording, recording reservation input, and the like.

  The operation unit 110 receives a control signal transmitted from a remote controller (remote control terminal) (not shown) and an operation capable of receiving a direct input from the user and outputting the control signal to the timer microcomputer 109 and the MPU 105. A panel 110A.

  FIG. 2 is a flowchart showing an operation performed by the MPU 105 of the HDD-equipped DVD recorder according to the embodiment of the present invention. This operation is performed when the double recording key is pressed, that is, when data recording is instructed to both the optical disc 100 and the HD 300A. Here, it is assumed that the user has already considered recording the content on both the HD 300A and the optical disc 100 at the start of recording the content on the HD 300A. In such a scene, the user presses the double recording key.

  When the double recording key is pressed, the MPU 105 instructs the optical disc drive 200, the HDD 300, etc., and starts recording on the optical disc 100 and the HD 300A (S1). Thereby, data from the input source is sequentially input to the encoder 103. Then, the encoder 103 sequentially encodes the data and stores the encoded recording data in the buffer memory 400A.

FIG. 3 is a diagram illustrating a flow of data input from an input source.
As shown in FIG. 3, the MPU 105 starts storage management of the buffer memory 400A (S2).

  As shown in FIG. 3, the MPU 105 instructs the data processor 400 to supply the recording data currently stored in the buffer memory 400A to the optical disc drive 200 and the HDD 300, respectively (S3).

The MPU 105 determines whether or not the supply of the recording data currently stored in the buffer memory 400A to the optical disc drive 200 and the HDD 300 has been completed (S4). Here, the optical disc drive 200 has a buffer memory 200A. When the buffer memory 200A becomes full or almost full, that is, before the buffer memory 200A overflows, the optical disc drive 200 refuses to supply recording data from the data processor 400. The reason is to prevent buffer overflow. The data processor 400 temporarily stops the supply of recording data to the optical disc drive 200. Thereby, the buffer overflow of the buffer memory 200A can be prevented. Then, the data processor 400 waits for a predetermined time and supplies the recording data to the optical disc drive 200 again.
The buffer memory 200A holds recording data so that the recording operation is not interrupted during recording on the optical disc 100. This is because if the buffer memory 200A is emptied and the recording operation is interrupted, that is, if the buffer memory 200A underflows, the optical disk 100 is left with a trace due to the laser beam and a joint is formed. Therefore, the data processor 400 waits for a predetermined time and supplies the recording data to the optical disc drive 200 again. Further, the data processor 400 supplies the recording data to the optical disc drive 200 before the data amount of the buffer memory 200A becomes empty, that is, before the buffer memory 200A underflows. As a result, it is possible to prevent a trace from the laser light from remaining and forming a joint on the optical disc 100.

When the supply to the optical disc drive 200 and the HDD 300 is completed, the MPU 105 instructs the data processor 400 to update the contents of the buffer memory 400A with the data newly input from the encoder 103 (S5). As a result, new recording data is stored in the buffer memory 400A.
Here, the data processor 400 maintains all the data currently stored in the buffer memory 400A until the instruction of S5 of the MPU 105 is given. That is, the data processor 400 restricts updating of the contents of the buffer memory 400A.

  The MPU 105 determines whether or not the recording to the optical disc drive 200 and the HDD 300 is completed (S6). This determination is performed by examining whether or not the recording data stream has reached the end, or by confirming whether or not the timer microcomputer 109 has instructed the end of recording.

  If it is determined that recording on the optical disc drive 200 and HDD 300 has not been completed, the MPU 105 returns to S3 and continues the processing. That is, during recording, the MPU 105 repeats the operations from S3 to S5.

  If it is determined that the recording to the optical disc drive 200 and the HDD 300 is completed, the MPU 105 records the control information in the optical disc drive 200 and the HDD 300 (S7), and ends this processing. More specifically, the MPU 105 causes the data processor 400 to create a UDF (Universal Disc Format) and supply it to the optical disc drive 200. The optical disc drive 200 records UDF on the optical disc 100. In addition, the MPU 105 causes the data processor 400 to create a predetermined file system (such as FAT) and supply it to the HDD 300. The HDD 300 records a predetermined file system on the HD 300A.

As described above, even when the recording of the content on both the HD 300A and the optical disc 100 is already considered at the start of the recording of the content on the HD 300A, the user dubbs the content onto the optical disc 100 after recording the content on the HD 300A. You do n’t have to go through the steps.
That is, since the contents are simultaneously recorded on both the media of the HD 300A and the optical disc 100, it is possible to shorten the time for which the user waits. Moreover, since the user only has to instruct recording of the content once, it is possible to save time and effort. Therefore, user convenience can be improved.
