Description
Technical field
The present invention relates to computer technology, more particularly to a kind of disc reading method and device.
Background technology
Currently, journalism content resource information and important history information of appearing in the newspapers are deposited by way of imprinting CDs
Storage and backup, but these data of optical disk are only saved 3 to five years, find that data very when information extraction is carried out
It is difficult to read, the slow even problems such as unsuccessfully of reading speed cause the loss of precious data.
Cause data above reading speed slow and low success rate of main cause be, CD after certain storage time,
Its readable hydraulic performance decline, when the data file wherein preserved it is many, it is broken in the case of, directly reading CD-ROM drive needs repeatedly on CD
Addressing positioning, and position success rate is relatively low, causes copy to fail.
The content of the invention
The present invention provides a kind of disc reading method and device, to the data text for solving to preserve when CD in the prior art
Part is more, it is broken in the case of, directly read that reading speed that CD-ROM drive brings is slow and low success rate of problem.
The first aspect of the invention is to provide a kind of disc reading method, including：
When detecting CD in CD-ROM drive, the image file of the CD is generated in high speed storing medium；
The image file is mapped as virtual drive；
By under the data duplication in the virtual drive to destination path.
The second aspect of the invention is to provide a kind of disc accessing, including：
Mirror module, for when detecting CD in CD-ROM drive, the mirror of the CD to be generated in high speed storing medium
As file；
Virtualization modules, for the image file to be mapped as into virtual drive；
Read module, for by under the data duplication in the virtual drive to destination path.
The solution have the advantages that：By generating the image file of CD in high speed storing medium, and mirror image is literary
Part is mapped as virtual drive, then by under the data duplication in virtual drive to destination path, it is to avoid when directly reading CD-ROM drive
Addressing positioning on CD repeatedly, improves the reading speed and success rate of data of optical disk.
Brief description of the drawings
Fig. 1 is a kind of schematic flow sheet of disc reading method provided in an embodiment of the present invention；
Fig. 2 is a kind of structural representation of disc accessing provided in an embodiment of the present invention.
Embodiment
Fig. 1 is a kind of schematic flow sheet of disc reading method provided in an embodiment of the present invention.As shown in figure 1, this method
Including：
101st, when detecting CD in CD-ROM drive, the image file of the CD is generated in high speed storing medium.
For example, when detecting CD in CD-ROM drive, disc accessing generates described in high speed storing medium
The image file of CD.Specifically, high speed storing medium refers to that reading speed is more than 70 megabyte per seconds（MB/s）Storage be situated between
Matter, such as local hard drive, fibre disk cabinet etc..
Further, the image file that the CD is generated in high speed storing medium, including：
To isolate（Isolation, abbreviation ISO）Data format generates the mirror image text of the CD in high speed storing medium
Part.
Under normal circumstances, for 4.6 gigabytes in 4 times of speed CD-ROM drives（Gigabyte, abbreviation GB）Capacity it is recordable
Formula digital versatile disc（Digital Versatile Disc-Recordable, abbreviation DVD-R）, it is raw in local hard drive
Image file into the DVD-R needs about 15~16 minutes.
102nd, the image file is mapped as virtual drive.
, it is necessary to which the corresponding drive of given virtual drive, accordingly, 102 include during mapping：
The image file is mapped as to the virtual drive of the specified drive of correspondence.
Specifically, this specifies drive can be pre-assigned or user specifies in mapping process.It is logical
Often, this specifies drive to be the drives different from existing drive in high speed storing medium, such as is Z:.
103rd, by under the data duplication in the virtual drive to destination path.
Specifically, the duplication in 103 at least includes both of which, i.e. automatic mode and manual mode.
In automatic mode, 103 include：
All data in the specified drive are automatically copied under the destination path.
Specifically, the destination path can be pre-set.
In a manual mode, 103 include：
The file and Folder List of the CD are obtained from the specified drive, and is presented；
The destination path and file or folder to be copied are determined according to user instruction；
The file or folder to be copied is copied under the destination path.
Specifically, the presentation can be presented at the interface of disc accessing with list mode.
Image file is mapped as by the embodiment of the present invention by generating the image file of CD in high speed storing medium
Virtual drive, then by under the data duplication in virtual drive to destination path, it is to avoid directly read during CD-ROM drive anti-on CD
Multiple addressing positioning, improves the reading speed and success rate of data of optical disk.It should be noted that the embodiment of the present invention is applied to
Many, the broken CDs of the data files of all preservations, no matter holding time length, or currently using CD, wherein, it is right
In the CD that the holding time is longer, due to optical disc surface oxidation, cause the reading speed that reads every time slow and success rate is low, this hair
The effect of bright embodiment becomes apparent from.Through actual test, for the DVD-R of 4.6GB capacity, directly read about using prior art
60~100 minutes are needed, and success rate is only 70%, and taken around 25 minutes using the method for the embodiment of the present invention, success rate
Reach 98%.
Fig. 2 is a kind of structural representation of disc accessing provided in an embodiment of the present invention.As shown in Fig. 2 the device
Including：
Mirror module 21, for when detecting CD in CD-ROM drive, the CD to be generated in high speed storing medium
Image file；
Virtualization modules 22, for the image file to be mapped as into virtual drive；
Read module 23, for by under the data duplication in the virtual drive to destination path.
Specifically, high speed storing medium refers to that reading speed is more than 70 megabyte per seconds（MB/s）Storage medium, such as this
Ground hard disk, fibre disk cabinet etc..
Further, mirror module 21 specifically for：When detecting CD in CD-ROM drive, with ISO data formats in height
The image file of the CD is generated in fast storage medium.
Further, virtualization modules 22 specifically for：The image file is mapped as the virtual of the specified drive of correspondence
CD-ROM drive.
Alternatively, read module 23 specifically for：
All data in the specified drive are automatically copied under the destination path.
Alternatively, read module 23 specifically for：
The file and Folder List of the CD are obtained from the specified drive, and is presented；
The destination path and file or folder to be copied are determined according to user instruction；
The file or folder to be copied is copied under the destination path.
The present embodiment is implemented with reference to a kind of disc reading method provided in an embodiment of the present invention.The embodiment of the present invention
Virtual drive is mapped as by generating the image file of CD in high speed storing medium, and by image file, then by virtual optical
Data duplication in drive is under destination path, it is to avoid addressing positioning when directly reading CD-ROM drive on CD repeatedly, improves
The reading speed and success rate of data of optical disk.It should be noted that the embodiment of the present invention is applied to the data file of all preservations
Many, broken CD, no matter holding time length, or currently using CD, wherein, for the light that the holding time is longer
Disk, due to optical disc surface oxidation, causes that the reading speed that reads every time is slow and success rate is low, the effect of the embodiment of the present invention is brighter
It is aobvious.Through actual test, for the DVD-R of 4.6GB capacity, directly read and taken around 60~100 minutes using prior art, and
Success rate is only 70%, and is taken around 25 minutes using the method for the embodiment of the present invention, and success rate reaches 98%.
