Moreover record reproducing control part 26 reads from non-volatile storage part 3 or hybrid CD 5 and upgrades OS, and send to CPU9 through interface portion 8 according to the indication from false judgment portion 28.
(update processing of OS)
Below with reference to Fig. 6, explain being kept at the update processing of upgrading OS and being carried out in non-volatile storage part 3 that hybrid drive 1 had and the hybrid CD 5.As prerequisite, imagine hybrid CD 5 and be seated in the hybrid drive 1.
In PC16; When receiving when carrying out indication from the OS update processing of input media 18; Perhaps sent when regularly the OS update processing is carried out indication automatically and (in S101, be " being "); Communication control unit 13 inserts the goods producer website of OS according to the control indication from CPU9 via communication network 19.Then, communication control unit 13 obtains the lastest imformation (S102) of OS from the goods producer website.Control indication according to CPU9 is applied to the lastest imformation of obtaining (S103) among the OS that is kept among the HDD12.Then, image file is used in the guiding of the OS after the CPU9 generation is upgraded.Then, image file is used in the guiding of the OS that CPU9 generated, promptly upgraded OS and sent to hybrid drive 1 (S104).
In hybrid drive 1, lastest imformation is obtained portion 25 through interface portion 8, has upgraded OS (S105) from the main part reception of PC16.Then, lastest imformation is obtained the OS of renewal that portion 25 will obtain and is sent to record reproducing control part 26, and the OS of renewal that indication record reproducing control part 26 will be kept in the non-volatile storage part 3 is rewritten into last state.
Record reproducing control part 26 is according to the indication of obtaining portion 25 from lastest imformation, upgrades the OS of renewal (S106) that OS is rewritten into last state with being kept in the non-volatile storage part 3.So, in PC16, not only can make the OS of renewal that is kept among the HDD12 become last state, the duplicated record that upgrades OS that can also edition upgrading be become last state is in the non-volatile storage part 3 that hybrid drive 1 is had.
In addition; Upgrade upgrading in OS and the RE layer 7 that is kept at hybrid CD 5 (in S107, being " being ") after the consistent synchronous indication of OS when record reproducing control part 26 receives to make to be kept in the non-volatile storage part 3 from synchronous indication portion 29, then from non-volatile storage part 3, read and upgrade OS.Then, indication record reproducing portion 4 is rewritten into the OS of renewal (S109) that from this non-volatile storage part 3, reads with the OS that upgrades that is recorded in the RE layer 7.
That is, in PC16, edition upgrading becomes the backup of upgrading OS of last state not only can be recorded in the non-volatile storage part 3 that hybrid drive 1 had, and can also be recorded in the hybrid CD 5.
As stated; Have only when hybrid drive master control part 2 has read specific program and key information (S108) from ROM layer 6; Record reproducing control part 26 could be according to the synchronous indication that comes motor synchronizing indication portion 29; Controlling recording playback portion 4 is rewritten into the content of upgrading OS (S109) that is kept in the non-volatile storage part 3 with the content of upgrading OS that is recorded in the RE layer 7.
In S109, rewrite the finishing dealing with of the content upgraded OS after, hybrid drive 1 will upgrade the result and send to PC16 (S110).And PC16 receives said renewal result (S111).
(OS reinstall processing)
Below with reference to Fig. 5 and Fig. 7, in PC16, starting to handle or reinstall to handle and describe because of the OS that carries out under the situation that OS can't carry out that upgrades that exists defective to cause being kept among the HDD12.Fig. 5 is the figure that handles or reinstall the primary structure of the relevant PC16 of processing with startup in the expression embodiment of the present invention.In Fig. 5,, only show with starting and handle or reinstall the software configuration of handling relevant hybrid drive 1 and main part 60, and omitted explanation about miscellaneous part for the ease of explanation.
In hybrid drive 1, handle relevant software configuration as handling or reinstall with the startup of OS, hybrid drive master control part 2 has record reproducing control part 26, reads portion 27 and the false judgment portion 28 of obtaining that indicate.These functional blocks are explained hereinbefore, therefore omit relevant explanation at this.
In addition, in main part 60, as handling or reinstall and handle relevant software configuration with the startup of OS, the functional block that master control part 90 is had comprises: start handling part 91, starting state judging part 92 and OS and read indication portion 93.Master control part 90 realizes through CPU9, and each functional block can be through by CPU9 fetch program from HDD12, and carries out these programs by Installed System Memory 11 and realize.Yet the program of each functional block that is used for realizing that master control part 90 is had is not limited to be kept at HDD12.For example, this program can be recorded in the hybrid CD 5 in advance, and CPU9 reads this program through hybrid drive 1 from said hybrid CD 5 then.
Like Fig. 5 and shown in Figure 7, start the operation indication (the startup indication of power source ON PC16 such as (connections)) (in S201, being " being ") that handling part 91 is accepted according to input media 18, the renewal OS of reading and saving in HDD12 carries out (S202).
Starting state judging part 92 is used for judging whether start handling part 91 normally carries out OS (S203).Starting state judging part 92 can't normally be carried out OS (in S203, being " denying ") as if judging, and then this judged result is sent to OS and reads indication portion 93.On the other hand, starting state judging part 92 then as normal conditions, is handled (S213) through the startup that startup handling part 91 continues to carry out OS and proceed PC16 if judge normal execution OS (in S203, being " being ").
OS reads indication portion 93 according to the notice that can't normally carry out the judged result of OS from starting state judging part 92, and indication hybrid drive 1 starts OS or reinstalls OS.Be specially, OS reads 93 pairs of hybrid drives 1 of indication portion and sends the indication of reading OS.That is, send the transmission request (S204) of having upgraded OS to hybrid drive 1.
In hybrid drive 1, read indication and obtain portion 27 and obtain the OS that reads indication portion 93 from OS via interface portion 8 and read indication (send and ask) (S205).Read and indicate the portion that obtains 27 to read indication according to the OS that is read 93 transmissions of indication portion by OS, misdirection judging part 28 judges whether the OS that is kept in the non-volatile storage part 3 exists defective.
There is not defective (in S207, being " being ") in false judgment portion 28 as if judging, and then indicates record reproducing control part 26 from non-volatile storage part 3, to obtain and upgrades OS.When record reproducing control part 26 obtain upgrade OS after, through interface portion 8 this has been upgraded OS and has sent to and start handling part 91 (S208).Start handling part 91 and carry out the OS of renewal that sends by record reproducing control part 26, carry out the startup of PC16 and handle (S209).Thus, the PC16 startup is kept at the OS of renewal in the non-volatile storage part 3, then, this has been upgraded OS be reinstalled in (S210) among the HDD12.
On the other hand, there is defective (in S207, being " denying ") in false judgment portion 28 as if judging, and then indicates record reproducing control part 26, from hybrid CD 5, obtains and upgrades OS.Record reproducing control part 26 is according to the indication from false judgment portion 28, and controlling recording playback portion 4 reads in hybrid CD 5 and upgrades OS.Record reproducing portion 4 reads from the RE layer of hybrid CD 5 and upgrades OS according to the control indication from record reproducing control part 26, and this has been upgraded OS sends to record reproducing control part 26 (S211).
