Servo information writing system |
摘要 |
The present invention intends to provide a servo information writing system capable of writing servo information to an information recording disk received in a cartridge and having a relatively small storage capacity, without design modification of the disk and without decrease in storage capacity of the disk. To this end, the servo information writing system comprises: a disk loading portion for loading thereon an information recording disk received in a cartridge and for rotating the disk when the disk is loaded thereon; a hard disk to which clock information is written and which rotates together with the disk loading portion; a head disposed in proximity to the information recording disk as loaded on the disk loading portion to write servo information to the disk; a head disposed in proximity to the hard disk to exchange clock information with the hard disk; and a servo information forming section for forming servo information with the clock information read by the latter head as a cycle and supplying the thus-formed servo information to the former head.
