Abstract

PURPOSE:To effectively utilize a disk by executing the positioning of >=2 actuators with a servo pattern to be recorded to one servo surface. CONSTITUTION:Magnetic disks 2 are fit to a spindle 1 and a servo pattern is formed to one surface of the disks. A first carriage 3 is composed of a first servo head 7, a first data head 6 to be positioned by this head 7 and a guide arm 5 to support these heads. In the same way, a second carriage 4 is composed of a servo head 9, a data head 8 and a guide arm 5. The servo pattern surface 10 is formed with being divided by the servo heads 7 and 9 such as areas 11 and 12. Thus, one surface is enough for the servo pattern and the positioning of high accuracy can be executed.
