Composite type recording apparatus, data writing method and data writing program
There is provided a composite type recording apparatus restricting write operations depending on the type of a connected host apparatus, including a recording medium having a first data region, a non-volatile storage medium having a second data region and an identification information table for integrating and managing the first and second data region, an information selection section for selecting positional information having predetermined identification information from the identification information table according to the type of the host apparatus, a conversion section for converting positional information selected by the information selection section into positional information matching the first data region or positional information matching the second data region, a first write section for writing data supplied from the host apparatus in the first data region according to conversion process of the conversion section and a second write section for writing data supplied from the host apparatus in the second data region.
1. A composite type recording apparatus comprising:
a recording medium having a first data region with a plurality of first physical addresses affixed thereto;
a non-volatile storage medium having a second data region with a plurality of second physical addresses affixed thereto;
an interface section connectable to a host apparatus;
a recognition unit that determines if the host apparatus is connected to the interface section and that generates a recognition result indicating whether the host apparatus connected to the interface section is (i) a host apparatus capable of recognizing and discriminating between the recording medium and the non-volatile storage medium or (ii) a host apparatus incapable of recognizing and discriminating between the recording medium and the non-volatile storage medium; and
an information selection unit that selects a logical address according to the recognition result;
a conversion unit that converts the logical address selected by the information selection unit according to the recognition result into a first physical address associated with the first data region or second physical address associated with the second data region;
a data allocation unit that allocates data supplied from the host apparatus connected to the interface section to the first data region or the second data region according to an outcome of the conversion by the conversion unit; and
a write unit that (i) writes the data allocated to the first data region by the data allocation unit at a predetermined location of the first data region according to the first physical address and (ii) writes the data allocated to the second data region by the data allocation unit at a predetermined location of the second data region according to the second physical address.
2. The apparatus according to claim 1 , wherein:
the information selection unit selects the logical address from logical addresses that correspond to the first data region when the recognition result generated by the recognition unit indicates that the host apparatus connected to the interface section is the host apparatus incapable of recognizing and discriminating between the recording medium and the non-volatile storage medium, and
the information selection unit selects a logical address from logical addresses that correspond to the second data region when the recognition result generated by the recognition unit indicates that the host apparatus connected to the interface section is the host apparatus capable of recognizing and discriminating between the recording medium and the non-volatile storage medium.
3. A composite type recording apparatus comprising:
a recording medium having a first data region with a plurality of first physical addresses affixed thereto;
a non-volatile storage medium having a second data region with a plurality of second physical addresses affixed thereto;
an interface section connectable to a host apparatus;
a recognition section that recognizes the host apparatus connected to the interface section and that generates a recognition result indicating whether the host apparatus connected to the interface section is (i) a host apparatus capable of recognizing and discriminating between the recording medium and the non-volatile storage medium or (ii) a host apparatus incapable of recognizing and discriminating between the recording medium and the non-volatile storage medium;
an information selection section that selects a logical address according to the recognition result;
a conversion section that converts the logical address selected by the information selection section according to the recognition result into a first physical address associated with the first data region or a second physical address associated with the second data region;
a data allocation section that allocates data supplied from the host apparatus connected to the interface section to the first data region or the second data region according to an outcome of the conversion by the conversion section; and
a write section that (i) writes the data allocated to the first data region by the data allocation section at a predetermined location of the first data region according to the first physical address and (ii) writes the data allocated to the second data region by the data allocation section at a predetermined location of the second data region according to the second physical address.
