Title: Magnetic head selection system for magnetic disk device
Inventor: ICHIHARA MASAHIRO
IPC: G11B5/09
Filed: 1991-03-19
Abstract: PURPOSE:To prevent time loss due to the tracking adjustment. CONSTITUTION:Magnetic heads with an even head number are attached to a head arm 16 and the magnetic heads with an odd head number are attached to a head arm 26. The head number assigned by a controller 1 is stored in a head number register 3 and an adder 4 adds '1' to the number. A first gate 10 selects the head number with an even head number from among head numbers A and B outputted by the register 3 and the adder 4, and outputs a signal for selecting the magnetic head to a first head selector 11. The selector 11 gives servo information read out with the magnetic head to a first signal controller 13, and a first servo control part 14 controls a first head driving part 15 based on the information, adjusts the head position and conducts tracking. At the same time, a second gate 20 selects the odd number from among the head numbers A and B, and outputs the signal for selecting the magnetic head to a second head selector 21. Similarly, the tracking of the selected magnetic head is performed.
