A data copying method for one-to-many reproduction apparatus having a data buffer includes steps of: reading multiple data segments from source data into the data buffer, detecting newly connected random access devices, selecting the data segments from the data buffer individually for each of the random access devices, copying the respectively selected data segments into each of the random access devices, and determining whether each of the data segments in the data buffer has been copied into all the random access devices and whether any of the random access devices has stored all the data segments of the source data. Newly connected devices are allowable to improve efficiency. Segment selection prevents multiple devices from writing identical data synchronously and thereby prevents accumulation of identical electromagnetic leakage. Consequently, electromagnetic interference is reduced. |
