Abstract
PURPOSE: To provide a deskew device of less effect of drop-out, etc. by controlling reading-out of memory by the majority signal of the reprouction synchronizing signal of each channel and the synthesized clock of the clock of each channel.
CONSTITUTION: About half of the synchronizing sgnals of the frame signals formed of the frame synchronizing signal and data signal or other reproduced from each channel of a magnetic tape go through synchronizing detection circuits 21, 22 ... and are made to the majority synchronizing signal by a majority circuit provided with OR circuits, etc. Hence, even at the missing of any synchronizing signal owing to drop-out, etc., the synchronizing signals become good as the whole channel and go through a delay circuit 5 to reset an address counter 6 for read-out. On the other hand, by counting of the mean clock which has synchesized the clock of each channel being applied to the counter 6 in a clock synthesizing circuit, the reproduction data having been written in the multiport registers 11, 12... of the respective channels are read out from the counter 6, and the data having been absorbed of skew are produced without affected by any error owing to drop-out.
