Abstract: PURPOSE: To reduce the thickness while decreasing the cost and eliminating the danger of contact of wirings with a disk. CONSTITUTION: A metal thin plate 12 of the material for forming load beams 106, 107 integrates carriages 104, 105 connected from flexures 116, 117, VCM coils 102, 103 and the support plate 180 of a flexible board 100. Signal output lines 108 to 115 from magnetic heads 150, 150 and signal line 185 from the coils 102, 103 are directly integrally connected to the board 100 without solder connecting.

Abstract: Described is a magnetic disk apparatus including at least one magnetic disk 1 comprising a glass or ceramic substrate. Magnetic heads (3a, 3b) are arranged on opposite surfaces of the disk and are shifted with respect to one another in a radial direction. This shifting reduces the amount of crosstalk and signal deterioration caused by the electromagnetic coupling of the two heads.
