<p>PURPOSE:To realize a timing matching action and to improve recording accuracy by writing desired data into a floppy disk to be written and set into a 1st floppy disk drive (FDD) based on a clock signal as well as the index holedetecting signal recorded on a floppy disk set into a 2nd FDD. CONSTITUTION:A floppy disk 2a to be written is set into a 1st FDD1a and a means is provided to a detect an index hole of the disk 2a and to send it to a 2nd FDD1b. The FDD1b contains a means which records the index hole detecting signal onto a floppy disk 2b set into the FDD1b and at the same time records the external clock signals. Then the desired data is written onto the disk 2a set into the FDD1a based on the block signal as well as the index hole detecting signal recorded onto the disk 2b set into the FDD1b. In such a way, the highly accurate positioning is possible between a track and a head.</p> |
