Patent ID: 7489479

Claim:
An electrical lead suspension having partitioned air slots comprising: a laminate; a first plurality of signal traces in a first formed layer of said laminate; a second plurality of traces in said first formed layer of said laminate, wherein said second plurality of traces is selected from a group consisting essentially of signal traces and power traces; a dielectric layer of said laminate; a second formed layer of said laminate; a partition formed in said second formed layer of said laminate; and a plurality of narrow, periodic and repeating air slots in said second formed layer of said laminate, said narrow, periodic and repeating air slots being partitioned by said partition into a first pattern under said first plurality of signal traces and being partitioned by said partition into a second pattern under said second plurality of traces; wherein said second formed layer of said laminate with said plurality of narrow, periodic and repeating air slots supports said dielectric layer supporting said first plurality of signal traces and supports said dielectric layer supporting said second plurality of traces; wherein said narrow, periodic and repeating air slots of said first pattern are aligned perpendicular to a direction in which said first plurality of signal traces run, and wherein said narrow, periodic and repeating air slots of said second pattern are aligned perpendicular to a direction in which said second plurality of traces run; and wherein said air slots and said partition reduce/disrupt a read to write coupling and work like a shield against cross talk between adjacent signal conductor pairs.
