Abstract

In a mobile electronic device (11), at least either one of the read rate from a first recording medium (12) and the write rate in a second recording medium (13) is variable. A detection means (14) detects a force acting on the mobile unit, and a control means (14) controls at least either the variable read or write rate on the basis of the detection. Even while the moving unit moves, data in the first recording medium (12) can be stably saved in the second recording medium (13), improving the reliability. Data in the first recording medium (12) can be saved in the second recording medium (13) within the shortest time corresponding to the moving state of the mobile unit, improving the convenience.

Claims

1. A mobile electronic device for saving data of a first recording medium in a second recording medium, wherein

at least one of a read rate of read means for reading out the data from the first recording medium and a write rate of write means for writing the data read out by the read means in the second recording medium is variable,

detection means detects a force acting on a mobile unit, and

control means controls at least either the variable read or write rate on the basis of the detection.

2. A mobile electronic device according to claim 1, wherein

prediction means predicts a prospective end time of the write, and

display means displays the prospective end time.

3. A mobile electronic device according to claim 1, wherein

first prediction means predicts a prospective end time of the write,

second prediction means predicts a prospective moving time of the mobile unit, and

the control means controls at least either one of the read and the write on the basis of the prospective end time and the prospective moving time.

4. A mobile electronic device according to claim 1, wherein the force includes a vibration.

5. A mobile electronic device for saving data of a first recording medium in a second recording medium, wherein

at least one of a read rate of read means for reading out the data from the first recording medium and a write rate of write means for writing the data read out by the read means in the second recording medium is variable,

detection means detects an error rate in either one of the read and the write, and

the control means controls at least either the variable read or write rate on the basis of the detection.

6. A mobile electronic device according to claim 5, wherein

prediction means predicts a prospective end time of the write, and

display means displays the prospective end time.

7. A mobile electronic device according to claim 5, wherein

first prediction means predicts a prospective end time of the write,

second prediction means predicts a prospective moving time of the mobile unit, and

the control means controls at least either one of the read and the write on the basis of the prospective end time and the prospective moving time.

8. A mobile electronic device for saving data of a first recording medium in a second recording medium, wherein

at least one of a read rate of read means for reading out the data from the first recording medium and a write rate of write means for writing the data read out by the read means in the second recording medium is variable,

detection means detects a force acting on a mobile unit and an error rate in either one of the read and the write, and

control means controls at least either the variable read or write rate on the basis of the detection.

9. A mobile electronic device according to claim 8, wherein

prediction means predicts a prospective end time of the write, and

display means displays the prospective end time.

10. A mobile electronic device according to claim 8, wherein

first prediction means predicts a prospective end time of the write,

second prediction means predicts a prospective moving time of the mobile unit, and

the control means controls at least either one of the read and the write on the basis of the prospective end time and the prospective moving time.

11. A mobile electronic device according to claim 8, wherein the force includes a vibration.

12. A data read/write rate control method for a mobile electronic device for saving data of a first recording medium in a second recording medium, wherein

at least one of a read rate for reading out the data from the first recording medium and a write rate for writing the readout data in the second recording medium is variable, and

the method comprises

the first detection step of detecting a force acting on a mobile unit,

the second detection step of detecting an error rate in either one of the read and the write, and

the control step of controlling at least either the variable read or write rate on the basis of the first or second detection.

13. A data read/write rate control method for a mobile electronic device according to claim 12, further comprising

the prediction step of predicting a prospective end time of the write, and

the display step of displaying the prospective end time.

14. A data read/write rate control method for a mobile electronic device according to claim 12, wherein the method further comprises

the first prediction step of predicting a prospective end time of the write, and

the second prediction step of predicting a prospective moving time of the mobile unit, and

at least either one of the read and the write is controlled in the control step on the basis of the prospective end time and the prospective moving time.

15. A data read/write rate control method for a mobile electronic device according to claim 12, wherein the force includes a vibration.
