Abstract

PURPOSE:To prevent the skip of block, by increasing the write-in current of control signal for data block detection in comparison with that of data section. CONSTITUTION:The write-in data 6 consists of preample 1, postample 2 which are the control signal and data 3 recorded between them. When the write-in instruction 5 is input to the write-data generating circuit 9, the write-in instruction 5 is input to the current control circuit 10 and the write-in voltage generating circuit 11 at the same time. After that, the recording medium reaches to a given speed, allowing the write-in data 6 from the upper rank device to be fed to the write data generating circuit 9 and to drive the write-in current generating circuits 12, 13 and 14. The information of the preample 1 in the write-in data 6 is detected with the write data generating circuit 9, the high current control signal 7 is generated at the current control circuit 10 to increase the write-in current 8. Thus, the detection mistake of the data block is avoided.
