Note that the operation input unit 8 may be an operation button that issues a reproduction command, or may be replaced with a reception unit that receives a reproduction command transmitted from a remote controller (not shown).

  The timer 9 is used for measuring the reproduction time.

  For example, the CPU 10 implements various processing units shown below by reading a program recorded on a computer-readable recording medium (not shown) and executing the program.

  The HDD recording information processing unit 10a measures the current date and time, and when receiving a recording start signal from the chipset 7, acquires information about the channel of the program received by the TV tuner from the TV tuner 4.

  The HDD recording information processing unit 10a acquires recording information related to AV stream data (program) in the recording AV stream data storage unit 6a based on the current date and time and channel information, for example, from the EPG, and the recording information is recorded. The information is stored in the information storage unit 6d (see FIG. 3). At this time, recording destination HDD information corresponding to the recording information is not stored.

  When the recording information is stored in the recording information storage unit 6d, the HDD recording information processing unit 10a provides the recording information to the HDD determination processing unit 10b (specifically, the determination unit 10b1).

  The HDD determination processing unit 10b determines the HDD to be used from among the HDDs 1 to 3.

  For example, when receiving the recording information, the HDD determination processing unit 10b is based on the accumulated reproduction time and accumulated recording time (see FIG. 2) managed for each HDD 1 to 3 in the reproduction R recording W accumulated time information storage unit 6c. Thus, the HDD to be the recording destination (hereinafter referred to as “recording destination HDD”) is determined from among the HDDs 1 to 3.

  Upon receiving the HDD identifier and the recording destination identifier, the chip set 7 associates the HDD identifier with the recording information not yet associated with the recording destination HDD information and stores it in the recording information storage unit 6d as the recording destination HDD information. (See FIG. 3).

  The chip set 7 stores the information stored in the recording information storage unit 6d in any of the HDDs 1 to 3 (hereinafter referred to as HDD 1). For example, when the power is turned on, the chip set 7 reads the recording information and the recording destination HDD information from the HDD 1 and stores them in the recording information storage unit 6d.

  Upon receiving the HDD identifier and the recording destination identifier, the HDD switching processing unit 10c switches the HDD that is accessed as the recording destination by the chipset 7 to the HDD specified by the HDD identifier. When the recording destination HDD is switched, the HDD switching processing unit 10c provides the HDD identifier to the recording W writing processing unit 10d.

  Upon receiving the HDD identifier, the recording W writing processing unit 10d performs a recording process for recording the AV stream data stored in the recording AV stream data storage unit 6a in the HDD specified by the HDD identifier. Run with set 7.

  The recording W time processing unit 10e refers to the recording process of the recording W writing processing unit 10d, specifies the recording destination HDD (recording destination HDD) and the recording time, and determines the accumulated recording time for each of the HDDs 1 to 3. The calculation result is recorded in the reproduction R recording W cumulative time information storage unit 6c and the HDDs 1 to 3.

  In addition, when the HDD determination processing unit 10b (specifically, the recording destination determination unit 10b2) receives a playback command from the operation input unit 8, the HDD determination processing unit 10b records the HDD storing the program indicated by the playback command. The information storage unit 6d (see FIG. 3) is found and the HDD is determined to be used as a read destination HDD (read destination HDD).

  When the HDD determination processing unit 10b determines the read destination HDD, the HDD determination processing unit 10b sets the HDD identifier (for example, the names of HDD1 to 3) for identifying the read destination HDD and the read destination identifier indicating the read destination to the HDD switching. Provided to the processing unit 10c.

  Upon receiving the HDD identifier and the read destination identifier, the HDD switching processing unit 10c switches the HDD that is accessed as the read destination by the chipset 7 to the HDD specified by the HDD identifier. When the HDD switching processing unit 10c switches the reading destination HDD, the HDD identifier is provided to the reproduction R reading processing unit 10f.

  When receiving the HDD identifier, the reproduction R reading processing unit 10f reads the AV stream data (program) designated by the reproduction command received from the operation input unit 8 from the HDD specified by the HDD identifier, and the AV The stream data is stored in the playback AV stream data storage unit 6 b, and then playback processing for providing the AV stream data to the decoder 11 is executed using the chip set 7.

  In addition, the reproduction R reading processing unit 10f performs the reproduction process and manages the program performance. Specifically, the reproduction R reading processing unit 10f stores the reproduction result of the program based on the reproduction command in the reproduction result storage unit 6e (see FIG. 4).

  In addition, the reproduction R reading processing unit 10f stores the reproduction result of the program stored in the reproduction result storage unit 6e in any one of the HDDs 1 to 3 (hereinafter referred to as HDD2). Note that, for example, when the power is turned on, the chip set 7 reads the program playback record from the HDD 2 and stores it in the playback record storage unit 6e.

  The reproduction R time processing unit 10g refers to the reproduction process of the reproduction R reading processing unit 10f, specifies the read destination HDD and the reproduction time using the timer 9, and calculates the accumulated reproduction time for each of the HDDs 1 to 3. The calculation result is recorded in the reproduction R recording W accumulated time information storage unit 6c and the HDDs 1 to 3.

  The determination unit 10b1 is configured to record a program to be recorded (hereinafter, “recording schedule”) based on the reproduction result managed by the reproduction R reading processing unit 10f, that is, the reproduction result information stored in the reproduction result storage unit 6e. It is determined whether there is a high or low possibility of being reproduced. Note that the determination unit 10b1 specifies a program to be recorded using the recording information received from the HDD recording information processing unit 10a.

  The recording destination determining unit 10b2 determines an HDD to be a recording destination from among the plurality of HDDs 1 to 3 based on the determination result of the determining unit 10b1 and the cumulative reproduction time and cumulative recording time managed for each HDD. To do.

  The playback R recording W accumulated time information storage unit 6c, the recording W time processing unit 10e, and the playback R time processing unit 10g constitute an HDD management unit.

  Next, the operation will be described.

  FIG. 5 is a flowchart for explaining the operation of the recording / reproducing apparatus 100, mainly the operation of determining the recording destination HDD. Hereinafter, the operation of the recording / reproducing apparatus 100 will be described with reference to FIG. In the following, it is assumed that the recording / reproducing apparatus 100 records a program for 24 hours.

  The encoder 5 compresses the program (video signal and audio signal) received by the TV tuner 4 to generate AV stream data, and provides the AV stream data to the chip set 7.

  When the chip set 7 receives AV stream data from the encoder 5, the chip set 7 stores the AV stream data in the recording AV stream data storage unit 6a. When the chip set 7 starts to store the AV stream data in the recording AV stream data storage unit 6a, the chip set 7 provides a recording start signal to the HDD recording information processing unit 10a.

  When the HDD recording information processing unit 10a receives the recording start signal, the HDD recording information processing unit 10a acquires channel information from the TV tuner 4, and based on the channel information and the current date and time, the AV stream data (program) in the recording AV stream data storage unit 6a is acquired. ) Is acquired from the EPG, and then the recording information is stored in the recording information storage unit 6d using the chip set 7. This recording information is used as information for specifying AV stream data (program) in the recording AV stream data storage unit 6a (step S1).

  When the recording information is stored in the recording information storage unit 6d, the HDD recording information processing unit 10a provides the recording information to the determination unit 10b1.

  When receiving the recording information, the determination unit 10b1 refers to the playback record information in the playback record storage unit 6e via the chipset 7, and based on the playback record information, the program ( It is determined whether there is a high or low possibility that a program scheduled to be recorded will be reproduced (step S2).

  For example, the determination unit 10b1 first stores a playback record of a program that has the same channel and broadcast time as the program to be recorded and that has been recorded and played back during the past several weeks (for example, the past four weeks). Extracted from the reproduction result information in the section 6e.

  Subsequently, when the number of extracted programs is equal to or greater than a predetermined number (the threshold level), the determination unit 10b1 determines that the program scheduled to be recorded is “highly likely to be played”, while extracting the program. If the number of programs that have been recorded is less than a predetermined number (threshold level), it is determined that the program that is scheduled to be recorded is "not likely to be reproduced".

  Further, for example, the determination unit 10b1 extracts a program recorded and played back during the past several weeks (for example, the past week) from the playback record information, and the extracted program time (playback program time). Are accumulated for each broadcast period of the program (for example, in units of one hour). Subsequently, the determination unit 10b1 extracts a time zone in which the accumulated time is equal to or greater than a predetermined time (referred to as a threshold level). FIG. 6 is an explanatory diagram showing an example of a reproduction program time accumulated for each time zone.

  Subsequently, when the broadcast time zone of the program scheduled to be recorded is included in the extracted time zone, the determination unit 10b1 determines that the program scheduled to be recorded is “highly likely to be played”, When the broadcast time zone of the program scheduled to be recorded is not included in the extracted time zone, it is determined that the program scheduled to be recorded is “not likely to be reproduced”.

  In FIG. 6, the playback program time is graphed in the broadcast time zone. However, the determination unit 10b1 graphs the playback program time in the program channel or the program genre, and the program to be recorded depends on the result. It may be determined whether the possibility of reproduction is high or low.

  Also, the determination unit 10b1 determines whether the program scheduled to be recorded is likely to be reproduced based on the reproduction program time for each broadcast time zone and the broadcast content (EPG information or the like). Good.

  Subsequently, the determination unit 10b1 provides the determination result to the recording destination determination unit 10b2.

  When the determination result indicates that the program scheduled to be recorded is “highly likely to be reproduced”, the recording destination determination unit 10b2 from the reproduction R recording W accumulated time information storage unit 6c via the chipset 7 to each HDD1. 3 to 3 accumulated reproduction information 6c1 is read out.

  Subsequently, the recording destination determining unit 10b2 determines to use the HDD with the shortest cumulative reproduction time as the recording destination HDD (step S3).

  On the other hand, if the determination result of the determination unit 10b1 indicates that the program scheduled to be recorded is “not likely to be reproduced”, the recording destination determination unit 10b2 stores the reproduction R recording W accumulated time information via the chipset 7. The cumulative recording information 6c2 of each HDD1 to 3 is read from the unit 6c.

  Subsequently, the recording destination determining unit 10b2 determines to use the HDD having the shortest accumulated recording time as the recording destination HDD (step S4).

  Subsequently, the recording destination determination unit 10b2 provides the HDD identifier for identifying the recording destination HDD and the recording destination identifier to the chip set 7 and the HDD switching processing unit 10c.

  Upon receiving the HDD identifier and the recording destination identifier, the chip set 7 associates the HDD identifier with the recording information not associated with the recording destination HDD information and stores it in the recording information storage unit 6d as the recording destination HDD information ( (See FIG. 3).

  Thereafter, the chip set 7 stores the information stored in the recording information storage unit 6d in the HDD 1. Note that the chip set 7 reads the recording information and the recording destination HDD information from the HDD 1 and stores them in the recording information storage unit 6d when the power is turned on.

  When receiving the HDD identifier and the recording destination identifier, the HDD switching processing unit 10c switches the HDD that is accessed as the recording destination by the chipset 7 to the HDD specified by the HDD identifier (step S5).

  When the recording destination HDD is switched, the HDD switching processing unit 10c provides the HDD identifier to the recording W writing processing unit 10d.

  Upon receiving the HDD identifier, the recording W writing processing unit 10d performs a recording process for recording the AV stream data stored in the recording AV stream data storage unit 6a in the HDD specified by the HDD identifier. This is executed using the set 7 (step S6).

  The recording W time processing unit 10e refers to the recording process of the recording W writing processing unit 10d, calculates the accumulated recording time for each of HDDs 1 to 3, and calculates the calculation result as a reproduction R recording W accumulated time information storage unit. 6c and a recording process for recording in the HDDs 1 to 3 is executed using the chip set 7.

  According to the present embodiment, the HDD determination processing unit 10b determines a recording destination HDD from a plurality of HDDs based on the cumulative reproduction time and cumulative recording time managed for each of the HDDs 1 to 3.

  For this reason, it is possible to equalize the cumulative reproduction time and the cumulative recording time, which are actual drive times between HDDs. Therefore, it is possible to average the lifetime between HDDs and extend the lifetime of HDDs.

  In the present embodiment, the determination unit 10b1 determines whether or not the program scheduled to be recorded is likely to be reproduced based on the program reproduction results. The recording destination determination unit 10b2 determines a recording destination HDD from among the plurality of HDDs based on the determination result of the determination unit 10b1 and the cumulative reproduction time and cumulative recording time managed for each of the HDDs 1 to 3.

  For example, when the determination unit 10b1 determines that the program scheduled to be recorded is likely to be reproduced, the recording destination determination unit 10b2 sets the HDD with the shortest reproduction time as the recording destination HDD, and the determination unit 10b1 determines the program to be recorded. If it is determined that there is a low possibility of reproduction, the HDD with the shortest accumulated recording time is set as the recording destination.

  In this case, it is possible to prevent programs that have a high possibility of being reproduced from being concentrated on a specific HDD, and it is possible to average the lifetime between HDDs and extend the lifetime of the HDD. In addition, since programs that have a high possibility of being reproduced are recorded in the HDDs having the shortest accumulated reproduction time, the accumulated reproduction times can be leveled between the HDDs. In addition, since a program with a low possibility of being reproduced is recorded in the HDD having the shortest cumulative recording time, the cumulative recording time can be leveled between the HDDs.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.

(Second embodiment)
The lifetime of the HDD is shortened as the load accumulated in the HDD increases. The reason is that the deterioration of the electromagnetic characteristics, lubrication, and thermal characteristics of the magnetic head and the magnetic disk progresses rapidly as the cumulative load of the HDD increases.

  In the second embodiment of the present invention, the recording destination HDD is determined in consideration of the cumulative load of the HDD.

  FIG. 7 is a block diagram showing a recording / reproducing apparatus 100A according to the second embodiment of the present invention. In FIG. 7, the same components as those shown in FIG. Hereinafter, the second embodiment will be described focusing on differences from the first embodiment.

  In FIG. 7, in the recording / reproducing apparatus 100A, a recording W time processing unit 10e1 is used instead of the recording W time processing unit 10e, and a reproduction R time processing unit 10g1 is used instead of the reproduction R time processing unit 10g. A recording destination determination unit 10b3 is used instead of the determination unit 10b2.

  In FIG. 7, the recording W time processing unit 10e1 and the reproduction R time processing unit 10g1 weight the accumulated recording time and the accumulated reproduction time based on the difference between the recording and reproduction loads, and the weighted accumulated recording time and The accumulated reproduction time is stored in the reproduction R recording W accumulated time information storage unit 6c and the HDDs 1 to 3.

  For example, when a weighting coefficient of W (recording): R (reproduction) = 1: 0.5 is set, the recording W time processing unit 10e1 multiplies the accumulated recording time by the weighting coefficient “1”. The reproduction R time processing unit 10g1 manages the weighted cumulative reproduction time obtained by multiplying the cumulative reproduction time by the weighting coefficient “0.5”. The weighting coefficient is not limited to the above and can be changed as appropriate.

  If the determination unit 10b1 determines that the program scheduled to be recorded is likely to be played back, the recording destination determination unit 10b3 determines the HDD with the shortest weighted cumulative playback time as the recording destination.

  On the other hand, when the determination unit 10b1 determines that the program scheduled to be recorded is unlikely to be played back, the recording destination determination unit 10b3 adds the weighted cumulative playback time and the weighted cumulative recording time for each HDD and has the shortest time. The HDD is determined as a recording destination.

  FIG. 8 is a flowchart for explaining the operation of weighting the accumulated recording time. Hereinafter, an operation for weighting the accumulated recording time will be described with reference to FIG.

  The recording W time processing unit 10e1 specifies the recording destination HDD with reference to the recording process of the recording W writing processing unit 10d (step S7).

  Subsequently, the recording W time processing unit 10e1 refers to the recording process of the recording W writing processing unit 10d, identifies the recording time, and multiplies the recording time by a weighting coefficient “1.0” to obtain the weighted recording time. calculate. The recording W time processing unit 10e1 reads the accumulated recording time of the recording destination HDD from the reproduction R recording W accumulated time information storage unit 6c, and adds the weighted recording time to the accumulated recording time to obtain the latest accumulated recording time ( Weighted cumulative recording time) is calculated (step S8).

  Subsequently, the recording W time processing unit 10e1 updates the accumulated recording time of the recording destination HDD in the reproduction R recording W accumulated time information storage unit 6c to the latest accumulated recording time, and further stores the updated recording time in the recording destination HDD. The accumulated recording time is updated to the latest accumulated recording time (step S9).

  FIG. 9 is a flowchart for explaining the operation of weighting the cumulative reproduction time. Hereinafter, with reference to FIG. 9, an operation for weighting the accumulated reproduction time will be described.

  The reproduction R time processing unit 10g1 refers to the reproduction process of the reproduction R reading processing unit 10f and specifies the reading destination HDD (step S10).

  Subsequently, the playback R time processing unit 10g1 refers to the playback process of the playback R reading processing unit 10f, specifies the playback time using the timer 9, and multiplies the playback time by a weighting coefficient “0.5”. The weighted playback time is calculated. The reproduction R time processing unit 10g1 reads the accumulated reproduction time of the reading destination HDD from the reproduction R recording W accumulated time information storage unit 6c, adds the weighted reproduction time to the accumulated reproduction time, and obtains the latest accumulated reproduction time ( A weighted cumulative reproduction time) is calculated (step S11).

  Subsequently, the reproduction R time processing unit 10g1 updates the accumulated reproduction time of the reading destination HDD in the reproduction R recorded W accumulated time information storage unit 6c to the latest accumulated reproduction time, and further stores the updated reproduction time in the reading destination HDD. The accumulated playback time is updated to the latest cumulative playback time (step S12).

  FIG. 10 is a flowchart for explaining the operation of determining the recording destination HDD in the second embodiment. In FIG. 10, the same operations as those shown in FIG. 5 are denoted by the same reference numerals. Hereinafter, the operation for determining the recording destination HDD will be described focusing on the differences from the operation shown in FIG.

  When the determination result of the determination unit 10b1 indicates that the program scheduled to be recorded is likely to be reproduced, the recording destination determination unit 10b3 receives the reproduction R recording W accumulated time information storage unit 6c via the chipset 7. The cumulative reproduction information (weighted cumulative reproduction information) 6c1 of each HDD1 to 3 is read. Subsequently, the recording destination determining unit 10b3 determines to use the HDD with the shortest cumulative reproduction time as the recording destination HDD (step S3).

  On the other hand, when the determination result of the determination unit 10b1 indicates that the program scheduled to be recorded is unlikely to be reproduced, the recording destination determination unit 10b3, via the chipset 7, reproduces the recorded R recorded W accumulated time information storage unit 6c. Then, the cumulative reproduction information (weighted cumulative reproduction information) 6c1 and the cumulative recording information (weighted cumulative recording information) 6c2 of each HDD 1 to 3 are read.

  Subsequently, the recording destination determination unit 10b3 calculates the sum of the cumulative reproduction time and the cumulative recording time, that is, the cumulative load for each HDD, for each of the HDDs 1 to 3. The recording destination determination unit 10b3 determines to use the HDD with the shortest calculated sum as the recording destination HDD (step S13).

  According to the present embodiment, the recording W time processing unit 10e1 and the reproduction R time processing unit 10g1 weight the accumulated recording time and accumulated reproduction time based on the difference in load during recording and reproduction, and the weighted The accumulated recording time and accumulated reproduction time are stored in the reproduction R recording W accumulated time information storage unit 6c.

  In addition, when the program scheduled to be recorded is highly likely to be reproduced, the recording destination determination unit 10b3 sets the HDD with the shortest weighted reproduction time as the recording destination and is unlikely to reproduce the program scheduled to be recorded. In this case, the HDD having the shortest time obtained by adding the weighted cumulative reproduction time and the weighted cumulative recording time for each HDD is the recording destination.

  For this reason, since a program that is highly likely to be reproduced is recorded in the HDD with the shortest weighted accumulated reproduction time, the accumulated reproduction time can be leveled between the HDDs. A program with a low possibility of being reproduced is recorded in the HDD having the shortest time obtained by adding the weighted cumulative reproduction time and the weighted cumulative recording time, that is, the cumulative load is the smallest. It is possible to level the load accumulated between them.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.

(Third embodiment)
FIG. 11 is a block diagram showing a recording / reproducing apparatus 100B of the third embodiment of the present invention. In FIG. 11, the same components as those shown in FIG. The third embodiment will be described below with a focus on differences from the second embodiment.

  11, in the recording / reproducing apparatus 100B, the reproduction record storage unit 6e and the determination unit 10b1 are omitted from the recording / reproducing apparatus 100A shown in FIG. 7, and the recording destination determining unit 10b4 is used instead of the recording destination determining unit 10b3. . In the present embodiment, the reproduction R reading processing unit 10f does not perform reproduction performance processing.

  The recording destination determination unit 10b4 receives recording information from the HDD recording information processing unit 10a. When receiving the recording information, the recording destination determining unit 10b4 receives the accumulated reproduction information (weighted accumulated reproduction information) 6c1 of each HDD 1 to 3 from the reproduction R recording W accumulated time information storage unit 6c via the chipset 7. And the cumulative recording information (weighted cumulative recording information) 6c2.

  Subsequently, the recording destination determination unit 10b4 calculates the sum of the accumulated reproduction time and the accumulated recording time, that is, the accumulated load for each HDD, for each of the HDDs 1 to 3. The recording destination determination unit 10b4 determines to use the HDD with the shortest calculated sum as the recording destination HDD.

  According to the present embodiment, the program scheduled to be recorded is recorded in the HDD with the shortest time obtained by adding the weighted cumulative reproduction time and the weighted cumulative recording time, that is, the cumulative load is the smallest. It is possible to level the load accumulated between the HDDs.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.

(Fourth embodiment)
FIG. 12 is a block diagram showing a recording / reproducing apparatus 100C according to the fourth embodiment of the present invention. In FIG. 12, the same components as those shown in FIG. In the following, the fourth embodiment will be described focusing on differences from the first embodiment.

  In FIG. 12, in the recording / reproducing apparatus 100C, an overlap time processing unit 10i is added to the recording / reproducing apparatus 100 shown in FIG. 1, and a recording destination determining unit 10b5 is used instead of the recording destination determining unit 10b2. Instead of the W accumulated time information storage unit 6c, a reproduction R recording W accumulated time information storage unit 6cA is used.

  The reproduction R recording W accumulated time information storage unit 6cA displays the accumulated reproduction time, the accumulated recording time, and the accumulated overlap time obtained by accumulating the overlap time reproduced during recording for each HDD 1 to 3. Is read and stored once. For example, when the power is turned on, the chip set 7 reads the accumulated playback time, the accumulated recording time, and the accumulated overlap time from the HDDs 1 to 3 and stores them in the reproduction R recording W accumulated time information storage unit 6c.

  Note that an HDD different from the HDDs 1 to 3 for recording AV stream data may be used as a storage device from which the cumulative playback time, cumulative recording time, and cumulative overlap time are read.

  FIG. 13 is an explanatory diagram showing an example of the cumulative playback time, the cumulative recording time, and the cumulative overlap time stored in the playback R video recording W cumulative time information storage unit 6cA.

  In FIG. 13, the reproduction R recording W accumulated time information storage unit 6cA stores an accumulated reproduction time 6c1, an accumulated recording time 6c2, and an accumulated overlap time 6c3 for each of HDDs 1 to 3.

  Returning to FIG. 12, the duplication time processing unit 10i refers to the recording process of the recording W write processing unit 10d and the reproduction process of the reproduction R reading processing unit 10f, and the duplication that has been reproduced during recording on the same HDD. The accumulated overlap time obtained by accumulating the time is calculated for each HDD 1 to 3, and the calculation result is recorded in the reproduction R recording W accumulated time information storage unit 6cA and the HDDs 1 to 3.

  When the determination unit 10b1 determines that the program scheduled to be recorded is likely to be reproduced, the recording destination determination unit 10b5 determines the HDD having the shortest reproduction time as the recording destination, while the determination unit 10b1 determines the recording destination. If it is determined that the program is unlikely to be reproduced, it is determined that the HDD having the shortest time obtained by subtracting the accumulated overlap time from the sum of the accumulated reproduction time and the accumulated recording time in the same HDD is used as the recording destination.

  FIG. 14 is a flowchart for explaining the operation of determining the recording destination HDD in the fourth embodiment. In FIG. 14, the same operations as those shown in FIG. In the following, with reference to FIG. 14, the operation different from that of the first embodiment will be mainly described.

  When the determination result of the determination unit 10b1 indicates that there is a high possibility that the program scheduled to be recorded will be reproduced, the recording destination determination unit 10b5 uses the reproduction R recording W accumulated time information storage unit 6cA via the chipset 7. The accumulated reproduction information 6c1 of each HDD1 to 3 is read. Subsequently, the recording destination determination unit 10b5 determines to use the HDD with the shortest cumulative reproduction time as the recording destination HDD (step S3).

  On the other hand, if the determination result of the determination unit 10b1 indicates that the program scheduled to be recorded is unlikely to be reproduced, the recording destination determination unit 10b5 receives the reproduction R recording W accumulated time information storage unit 6cA via the chipset 7. Then, the cumulative reproduction information 6c1, the cumulative recording information 6c2, and the cumulative overlap time 6c3 of each HDD 1 to 3 are read out.

  Subsequently, the recording destination determination unit 10b5 calculates, for each HDD 1 to 3, a time obtained by subtracting the cumulative overlap time from the sum of the cumulative playback time and the cumulative recording time, that is, the actual driving time. The recording destination determination unit 10b5 determines to use the HDD having the shortest calculated time (actual driving time) as the recording destination HDD (step S14).

  According to the present embodiment, since a program that is highly likely to be reproduced is recorded in the HDD having the shortest accumulated reproduction time, the accumulated reproduction time can be leveled between the HDDs. In addition, programs that are unlikely to be played are recorded in HDDs that have the shortest actual drive time since the cumulative overlap time is subtracted from the sum of the cumulative playback time and cumulative recording time, that is, between HDDs. The driving time can be leveled.

  For this reason, it becomes possible to equalize the lifetime between HDDs, and to extend the lifetime of HDDs.

(5th Example)
FIG. 15 is a block diagram showing a recording / reproducing apparatus 100D of the fifth embodiment of the present invention. In FIG. 15, the same components as those shown in FIG. 12 are denoted by the same reference numerals. In the following, the fifth embodiment will be described focusing on the differences from the fourth embodiment.

  15, in the recording / reproducing apparatus 100D, the reproduction record storage unit 6e and the determination unit 10b1 are omitted from the recording / reproducing apparatus 100C shown in FIG. 12, and the recording destination determining unit 10b6 is used instead of the recording destination determining unit 10b5. . In the present embodiment, the reproduction R reading processing unit 10f does not perform reproduction performance processing.

  The recording destination determination unit 10b6 receives recording information from the HDD recording information processing unit 10a. When receiving the recording information, the recording destination determination unit 10b6 receives the accumulated reproduction information 6c1, the accumulated recording information 6c2, and the accumulated recording information 6c2 of each HDD 1 to 3 from the reproduction R recording W accumulated time information storage unit 6cA via the chipset 7. Read accumulated overlap time 6c3.

Subsequently, the recording destination determination unit 10b6 calculates, for each HDD 1 to 3, a time obtained by subtracting the accumulated overlap time from the sum of the accumulated reproduction time and the accumulated recording time, that is, the actual driving time. The recording destination determination unit 10b6 determines to use the HDD whose calculated time (actual driving time) is the shortest as the recording destination HDD. According to this embodiment, the program scheduled to be recorded includes the cumulative playback time and the cumulative recording. Since the time obtained by subtracting the cumulative overlap time from the sum of the times, that is, the actual drive time is recorded in the HDD with the shortest time, the actual drive time can be leveled between the HDDs.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.

(Sixth embodiment)
In the sixth embodiment of the present invention, the recording destination HDD is determined in consideration of the cumulative load of the HDD.

  FIG. 16 is a block diagram showing a recording / reproducing apparatus 100E according to the sixth embodiment of the present invention. In FIG. 16, the same components as those shown in FIG. Hereinafter, the sixth embodiment will be described focusing on differences from the fourth embodiment.

  In FIG. 16, in the recording / reproducing apparatus 100E, a recording W time processing unit 10e2 is used instead of the recording W time processing unit 10e, and a reproduction R time processing unit 10g2 is used instead of the reproduction R time processing unit 10g. The overlapping time processing unit 10i1 is used instead of the processing unit 10i, the playback R recording W accumulated time information storage unit 6cB is used instead of the playback R recording W accumulated time information storage unit 6cA, and instead of the recording destination determination unit 10b5. The recording destination determination unit 10b7 is used.

  In the following, based on the load on the HDD, it is assumed that the weighting coefficient is set to be W (recording) only: R (reproduction) only: W and R overlap = 1: 0.5: 1.8. A sixth embodiment will be described. The weighting coefficient is not limited to the above and can be changed as appropriate.

  The recording W time processing unit 10e2 refers to the recording processing of the recording W writing processing unit 10d and the reproduction processing of the reproduction R reading processing unit 10f, and the recording destination HDD and the recording only time during which only recording is performed. And for each HDD 1 to 3, the time only for the weighted cumulative recording is calculated by accumulating a value obtained by multiplying the recording only time by the weighting coefficient “1”.

  The recording W time processing unit 10e2 records only the weighted cumulative recording time in the reproduction R recording W cumulative time information storage unit 6cB and the HDDs 1 to 3.

  The reproduction R time processing unit 10g2 calculates the accumulated reproduction time in the same manner as the reproduction R time processing unit 10g, and refers to the recording process of the recording W writing processing unit 10d and the reproduction process of the reproduction R reading processing unit 10f. Then, the read-out HDD and the playback only time are specified, and the weighted cumulative playback is performed by accumulating a value obtained by multiplying the playback only time by the weighting coefficient “0.5” for each HDD 1 to 3. Only calculate the time.

  The reproduction R time processing unit 10g2 records the accumulated reproduction time and the weighted accumulation reproduction only time in the reproduction R recording W accumulated time information storage unit 6cB and the HDDs 1 to 3.

  When the overlap time is specified, the overlap time processing unit 10i1 calculates a weighted cumulative overlap time obtained by accumulating a value obtained by multiplying the overlap time by the weighting coefficient “1.8” for each of the HDDs 1 to 3.

  The overlapping time processing unit 10i1 records the weighted accumulated overlapping time in the reproduction R recording W accumulated time information storage unit 6cB and the HDDs 1 to 3.

  The reproduction R recording W accumulated time information storage unit 6cB reads the accumulated reproduction time, the weighted accumulated reproduction only time, the weighted accumulated recording only time, and the weighted accumulated overlap time from the HDDs 1 to 3 for each of the HDDs 1 to 3. Store once. For example, when the power is turned on, the chip set 7 reads the cumulative playback time, the weighted cumulative playback only time, the weighted cumulative recording only time, and the weighted cumulative overlap time from the HDDs 1 to 3 and stores them in the playback R recording W cumulative time information storage unit 6cB. To do.

  FIG. 17 shows the cumulative playback time 6c1, the weighted cumulative playback only time 6c4, the weighted cumulative recording only time 6c5, and the weighted cumulative overlap time 6c6 stored in the playback R recording W cumulative time information storage unit 6cB. It is explanatory drawing which showed an example.

  When the determination unit 10b1 determines that the program scheduled to be recorded is likely to be reproduced, the recording destination determination unit 10b7 determines to use the HDD with the shortest reproduction time as the recording destination HDD.

  Further, when the determination unit 10b1 determines that the program scheduled to be recorded is unlikely to be reproduced, the recording destination determination unit 10b7 sets the weighted cumulative reproduction only time, the weighted cumulative recording only time, and the weighted cumulative overlap time for each HDD. It is determined that the HDD with the shortest added time is used as the recording destination.

  FIG. 18 is a flowchart for explaining the operation of determining the recording destination HDD in the sixth embodiment. In FIG. 18, the same operations as those shown in FIG. 5 are denoted by the same reference numerals. Hereinafter, the operation for determining the recording destination HDD will be described focusing on the differences from the operation shown in FIG.

  When the determination result of the determination unit 10b1 indicates that the program scheduled to be recorded is likely to be played back, the recording destination determination unit 10b7 uses the playback R recording W accumulated time information storage unit 6cB via the chipset 7. The accumulated reproduction information 6c1 of each HDD1 to 3 is read. Subsequently, the recording destination determining unit 10b7 determines to use the HDD having the shortest cumulative reproduction time as the recording destination HDD (step S3).

  On the other hand, when the determination result of the determination unit 10b1 indicates that the program to be recorded is unlikely to be reproduced, the recording destination determination unit 10b7 receives the reproduction R recording W accumulated time information storage unit 6cB via the chipset 7. Then, the weighted cumulative reproduction only time 6c4, the weighted cumulative recording only time 6c5, and the weighted cumulative overlap time 6c6 of each HDD 1 to 3 are read.

  Subsequently, the recording destination determination unit 10b7 calculates the sum of the weighted cumulative reproduction only time, the weighted cumulative recording only time, and the weighted cumulative overlap time, that is, the cumulative load for each HDD, for each of the HDDs 1 to 3. The recording destination determining unit 10b7 determines to use the HDD with the shortest calculated sum as the recording destination HDD (step S15).

  According to the present embodiment, the cumulative recording only time, the cumulative playback only time, and the cumulative overlap time can be weighted based on the difference in load between recording and playback.

  In this case, since a program with a high possibility of being reproduced is recorded on the HDD having the shortest accumulated reproduction time, the accumulated reproduction time can be leveled between the HDDs. In addition, a program with a low possibility of being reproduced is recorded in the HDD with the shortest time that is the sum of the weighted cumulative reproduction only time, the weighted cumulative recording only time, and the weighted cumulative overlap time, that is, the accumulated load is the smallest. The load accumulated between the HDDs can be leveled.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.

When receiving the recording information, the recording destination determining unit 10b8 receives the weighted cumulative playback only time 6c4 and the weighted cumulative recording only time of each of the HDDs 1 to 3 from the playback R recording W cumulative time information storage unit 6cB via the chipset 7. 6c5 and the weighted cumulative overlap time 6c6 are read.

  Subsequently, the recording destination determining unit 10b8 calculates the sum of the weighted cumulative reproduction only time, the weighted cumulative recording only time, and the weighted cumulative overlap time, that is, the cumulative load for each HDD, for each of the HDDs 1 to 3. The recording destination determination unit 10b8 determines to use the HDD with the shortest calculated sum as the recording destination HDD.

  According to the present embodiment, for example, the cumulative recording only time, the cumulative playback only time, and the cumulative overlap time can be weighted based on the load difference during recording and playback. In this case, the program scheduled to be recorded is recorded in the HDD having the shortest time, ie, the accumulated load only, the weighted cumulative recording only time, the weighted cumulative recording only time, and the weighted cumulative overlap only time. It is possible to level the load accumulated between them.

  For this reason, it is possible to equalize the lifetime between HDDs and extend the lifetime of HDDs.
