Each of a plurality of storage devices (N&#x2212;1 to N-n) has a plurality of memory blocks for storing data. A data writing apparatus obtains error information which represents good blocks which can store data correctly, from the plurality of storage devices (N&#x2212;1 to N-n). The data writing apparatus determines a memory block in which data is to be written, in each of the plurality of storage devices (N&#x2212;1 to N-n), based on the obtained error information. The data writing apparatus controls the plurality of storage devices (N&#x2212;1 to N-n), and writes predetermined data in the determined memory blocks.

Data writing apparatus, data writing method, and program

A first storage unit is accessed randomly in a unit equal to or greater than a predetermined data unit. The first storage unit stores a target program required to be read randomly in a unit smaller than the data unit to execute. A second storage unit stores a reading program for reading the target program from the first storage unit. A control unit reads the target program from the first storage unit according to the reading program of the second storage unit. The control unit stores the read target program to a third storage unit that can be accessed in a unit smaller than the data unit. The control unit executes the target program stored in the third storage unit to gain access randomly to the first storage unit in a unit smaller than the data unit in a quasi manner.
