Abstract

PURPOSE: To eliminate the noise, by providing a holding means to hold both the data head which detects the record information and the servo-head which detects the servo-information via the arm mechanism connected to a mobile carriage plus the means that controls the position of the data head.
CONSTITUTION: Both the data head 4 and the servo-head 5 are attached to the arm 3 attached to the carriage 2. Now in case three sheets of disks are attached to the vertical shaft, the data head 4 counts of units SD1, SD2, SD3 and SD4 in that order from above. And the servo-head 5 counts four units FD1, FD2, FD3 and FD4 in that order from above. Then the data head SDc is set at the lowest position. The writein/read action is carried out based on the servo-information detected by the head SDc for the main control and with either one of the data heads. And for the precise control, the servo-information detected by the head FD2 is used to the head SD1.
