Magnetic recording head assembly support with a sinuous gimbal spring

DETAILED DESCRIPTION OF THE DRAWINGS Reference should now be had to the FIGS.
1 to 9 for a description of the preferred embodiment of the disclosure.
In FIGS.
1 and 2 there is shown a typical magnetic disk storage system 20 comprising a disk 21 having a central portion 21-1 with a top magnetic oxide coating 21-2.
The disk is preferably of the Winchester style having a film lubricant on the surface thereof such as sold by BASF or Minnesota Mining and Manufacturing Co.
(3M).
The disk 21 may also conventionally have a bottom magnetic coating so that additional head assemblies as disclosed herein, mounted to fly over the bottom coating, may read and write data on tracks of the bottom magnetic coating.
The disk 21 is conventionally supported by a shaft 23 driven in a manner well known in the art.
At 30 there is shown the multitrack head assembly of this invention supported by the disk housing 25 by bolts as shown with a portion thereof extending into a hole 25-1.
It should be understood that additional multitrack head assemblies 30 (shown dotted) in FIG.
1 may also be used if additional recording tracks are desired.
The assembly 30 comprises a top support member 30-1 having a projection 30-2 extending downwardly therefrom.
A loading spring device 31 e.
g.
, of berylium copper alloy having a plurality of load spring leafs 31-1 extending therefrom is supported by an inclined member 30-3 and bolts 30-4 as shown (see FIGS.
3 and 9).
The load spring leafs 31-1 support on the top thereof a flexible circuit 32 e.
g.
, Kapton having wires encapsulated therein for making connection to terminals 32-1 (see FIG.
4) which in turn are connected by connecting wires 32-3 to the individual heads 35 (FIGS.
4 and 5).
The heads 35 are supported by a slider 33 and a gimbal spring 34, all of which will now be more fully described.
At 33 there is shown a separate slider commonly termed a Winchester slider positioned below an associated load spring leaf 31-1.
Each of the sliders 33 as shown herein is for three track operation in the preferred embodiment, i
