Etching continuous periodic pattern on a suspension to adjust pitch and roll static attitude
A method of manufacturing a suspension for a head of a data storage device is disclosed, the method comprising etching at least one continuous cycle of a periodic pattern on the suspension, wherein a first part of the continuous cycle adjusts a pitch static attitude (PSA) of the suspension and a second part of the continuous cycle adjusts a roll static attitude (RSA) of the suspension.
1. A method of manufacturing a suspension for a head of a data storage device, the method comprising etching at least one continuous cycle of a periodic pattern on the suspension, wherein a first part of the continuous cycle adjusts a pitch static attitude (PSA) of the suspension and a second part of the continuous cycle adjusts a roll static attitude (RSA) of the suspension.
2. The method as recited in claim 1 , wherein etching the at least one continuous cycle comprises continuously etching with a laser.
3. The method as recited in claim 1 , wherein the suspension comprises a first and a second outer arm, and the method further comprises etching the at least one continuous cycle of the periodic pattern along only one of the arms.
4. The method as recited in claim 1 , wherein the periodic pattern comprises a square wave.
5. The method as recited in claim 1 , wherein the periodic pattern comprises a triangle wave.
6. The method as recited in claim 1 , wherein the periodic pattern comprises a sinusoidal wave.
7. The method as recited in claim 1 , further comprising etching at least two continuous cycles of the periodic pattern on the suspension.
8. The method as recited in claim 7 , further comprising configuring at least one of a period, duty cycle, and amplitude of at least one of the continuous cycles in order to adjust at least one of the PSA and RSA of the suspension.
9. A suspension for a head of a data storage device, the suspension comprising at least one continuous cycle of a periodic pattern etched on the suspension, wherein a first part of the continuous cycle adjusts a pitch static attitude (PSA) of the suspension and a second part of the continuous cycle adjusts a roll static attitude (RSA) of the suspension.
10. The suspension as recited in claim 9 , wherein the at least one continuous cycle of the periodic pattern is etched continuously with a laser.
11. The suspension as recited in claim 9 , wherein the suspension comprises a first and a second outer arm, and the at least one continuous cycle of the periodic pattern is etched along only one of the arms.
