Abstract:
A recording and producing device, comprising:hard disks, each hard disk having recording and reproducing time slots and a pre-assigned control time slot necessary for generation of commands with respect to a record/playback mode, said hard disks sequentially distributing a plurality of continuous data according to said time slots and recording and reproducing the continuous data thereon;a hard disk provided exclusively for recording and reproducing parity data of said distributedly recorded and reproduced data;means for detecting a write error produced in each said hard disk;means for rebuilding data as error data, to be recorded on the hard disk from which the write error is detected, based on the data of the remaining hard disks from each of which the write error is undetected, and the parity data; andmeans for controlling each said hard disk based on said pre-assigned control time slot;wherein when a write error occurs in one hard disk, the recording of data thereon is continuously performed together with the recording of data on other hard disks without effecting a spare sector reassign operation on the error-produced hard disk, anddata corresponding to the write error, said data being rebuilt within said controlled time slot, is recorded on an arbitrary sector on the hard disk from which the write error is detected.
