Figure 1B has showed that magnetic head cantilever shown in Figure 1A makes up more detailed structure.As shown in the figure, described magnetic head cantilever combination 200 comprises one group of actuating arm 204 that is positioned at the one end, and described each actuating arm 204 has the magnetic head fold piece combination (head gimbal assembly, HGA) 220 that are installed on its end and comprise described magnetic head 203.Described actuating arm 204 also comprises the pilot hole 222 that is used to locate comb type assembly tool (shippingcomb, figure does not show) formed thereon, and described comb type assembly tool is used in the magnetic head cantilever aggregate erection in the process of disc driver.Described magnetic head cantilever combination 200 also comprises the fan-shaped spacer portion (fantail spacer) 219 that is positioned at its other end and is integrated with voice coil loudspeaker voice coil 207 on it, and described actuating arm 204 is installed on the described fan-shaped spacer portion 219 by bearing arrangement 212.Flexible print circuit (flexible printed circuit, FPC) end of 206 is connected electrically with described magnetic head cantilever combination 200, and the other end of described flexible print circuit 206 is connected electrically with printed circuit board (PCB) 208.This electrical connection makes external control system can control described magnetic head cantilever combination 200.
As mentioned above, in the structure of magnetic head cantilever combination, for keeping suitable elastic force, this elastic force is by produce big or small identical of the contact of the aerodynamics between the disk of described magnetic head and rotation and lifting force institute balance that direction is opposite, in the manufacture process of magnetic head cantilever combination, the end of described magnetic head fold piece combination is bent downwardly slightly, so that produce predetermined elastic force.More specifically, be installed on distance between the adjacent magnetic head on the corresponding magnetic head fold piece combination less than the thickness of described disk.As a result, when the magnetic head cantilever combine and assemble is arrived disc driver, must use specific instrument, such as comb type assembly tool, so that installation process becomes easy.Particularly, in the installation process of magnetic head cantilever combination, described comb type assembly tool is inserted in the space that is formed between the adjacent magnetic head fold piece combination, be used to enlarge the distance between the adjacent magnetic head, thereby make disk under the situation that does not have to interfere with magnetic head, can be received in the described space, and then can not produce damage magnetic head and/or disk.
And for the disc driver with ramp designs, when described disc driver did not turn round, described magnetic head cantilever combination was removed its magnetic head up to described magnetic head from the position that is positioned at described magnetic disk surface and is docked on the described slope.Described slope has suitable structure so that a described yoke is berthed thereon, and has and the similar function of described comb type assembly tool, so that adjacent magnetic head is separated from each other.When described disc driver entry into service, described magnetic head cantilever combination moves apart magnetic head and magnetic head is moved to the magnetic disk surface direction from described slope, thereby with the position of corresponding head position on corresponding magnetic disk surface.
Therefore, in the assembling process of magnetic head cantilever combination, be necessary described magnetic head cantilever combination is rotated to and is moored on the described slope, thereby when assembling process finishes back and the running of described disc driver, the magnetic disk surface top that described magnetic head can be removed and be positioned to rotate from described slope.By convention, in the assembling process of magnetic head cantilever combination, described magnetic head is moored on the slope by using above-mentioned comb type assembly tool to realize, this is described below in conjunction with Figure 1A-1B and Fig. 2.
With reference to figure 1A-1B and Fig. 2, traditional comb type assembly tool 100 is an one-piece construction, and it comprises sliver (the comb finger) 170 of adjacent two magnetic heads 203 that are used to separate magnetic head cantilever combination 200 and comb nail (the comb pin) 120 of stationkeeping.Before described magnetic head cantilever combination 200 is installed to described disc driver 2, is inserted into by comb nail 120 in the pilot hole 222 of described magnetic head cantilever combination 200 and comb type assembly tool 100 is fixed to described magnetic head cantilever combination 200 comb type assembly tool 100.Then, the bearing arrangement 212 of described magnetic head cantilever combination 200 is pivotally mounted on the bottom 205 of described disc driver 2, and with the magnetic head 203 of described magnetic head cantilever combination 200 to 230 rotations of described slope, make described magnetic head 203 can be docked on the described slope 230.After described magnetic head 203 is moored to described slope 230, other assembly is such as top voice coil loudspeaker voice coil magnetic patch (top voice coil magnet, top voice coil loudspeaker voice coil magnetic patch 550 shown in Figure 12 A) disc driver as described in the locked instrument (latch device, the locked instrument 540 shown in Figure 12 A) that magnetic head cantilever makes up 200 positions and as described in being used to limit can be mounted to.
In the assembling process of above-mentioned parts, owing in described disc driver, can take place to vibrate or rock, in addition, owing to the combination of the magnetic head cantilever on the bottom that is installed in described disc driver can be around described bearing arrangement rotation, result ground, be docked in that magnetic head on the described slope may slip away from described slope and bump with other parts of described disc driver, may clash into the inwall of described disc driver such as described magnetic head, run foul of each other between the perhaps adjacent disk, and then cause destruction described magnetic head.Therefore, at above-mentioned parts for example in the assembling process of top voice coil loudspeaker voice coil magnetic patch and locked instrument, described magnetic head cantilever is combined in the whole process should keep relative fixed by suitable mode, described top voice coil loudspeaker voice coil magnetic patch in the disc driver and the locked instrument of being installed in be installed to up hill and dale in the described disc driver up to described parts, because can be controlled described magnetic head cantilever combination and the corresponding magnetic head position with respect to described slope.
Yet, because above-mentioned traditional comb type assembly tool contains the position comb nail fixing with respect to the remainder of described comb type assembly tool, particularly, described comb nail only can be inserted in the pilot hole of described magnetic head cantilever combination, described magnetic head cantilever makes up and the bottom of described disc driver and can not be inserted into simultaneously, as a result, this comb type assembly tool can not be provided in the assembling process of described other parts magnetic head with described magnetic head cantilever combination and be fixed to function on the described slope.Therefore, in above-mentioned assembling process, use several different methods/device that described magnetic head cantilever combination temporarily is fixed on the slope.
A kind of method commonly used is to form a plurality of indent ratchets (concave detent) on described slope.In the time of on being docked in this slope, described magnetic head be actually be docked on these indent ratchets and these ratchets with the magnetic head fixing within it.Yet, owing to be subjected to the restriction of described slope size, be difficult to form the enough big ratchet of the bodily form, the vibration that intensity is higher a little will cause the slip away ratchet on described slope of described magnetic head, and make magnetic head cantilever combination rotate freely around its bearing arrangement, easy like this cause damaging between magnetic head or the combination of described magnetic head cantilever and other parts that are arranged in the disc driver produce interference.
Another kind method uses independent locked mechanism (additional locking mechanism) that the magnetic head cantilever combination is remained on its position.For example, positioning guide column can be inserted into simultaneously pilot hole and be formed in the respective aperture on the bottom of disc driver,, temporarily the magnetic head cantilever combination is fixed on the bottom so that other parts are being assembled in the process of disc driver.Yet this locked mechanism that provides separately is time-consuming and be difficult to be removed after whole assembling process finishes.And this locked mechanism also is difficult to be incorporated in the robotization assembling process of magnetic head cantilever combination.In addition, provide this extra locked mechanism to increase manufacturing cost.
Therefore, be necessary to provide a kind of apparatus and method, so as easily with the magnetic head cantilever aggregate erection to disc driver and simplify its assembling process.
