Varying suspension arm length for magnetic storage device

A carriage for a magnetic storage device, comprising:

• a first carriage arm;
• a first read-write head assembly, comprising:
• a first suspension arm co-movably fixed to the first carriage arm and having a first-suspension-arm length extending from a proximate first-suspension-arm end of the first suspension arm to a distal first-suspension-arm end of the first suspension arm, wherein the proximate first-suspension-arm end is coupled to a distal end of the first carriage arm;
• and
• a first read-write head co-movably fixed to the first suspension arm and coupled to the distal first-suspension-arm end;
• and
• a second read-write head assembly, comprising:
• a second suspension arm co-movably fixed to the first carriage arm and having a second-suspension arm length extending from a proximate second-suspension arm end to a distal second-suspension arm end of the second suspension arm that is different from the first-suspension arm length, wherein the proximate second-suspension arm end is coupled to the distal end of the first carriage arm;
• and
• a second read-write head co-movably fixed to the second suspension arm.

A method comprising:

• rotating a first carriage arm radially outward from a first magnetic disc and toward a ramp support, wherein rotating the carriage arm radially outward from the magnetic disc causes:
• a first suspension arm co-movably fixed to the first carriage arm and having a first-suspension arm length extending from a proximate first-suspension-arm end of the first suspension arm to a distal first-suspension-arm end of the first suspension arm, to:
• move toward and contact a first-ramp surface of a first ramp of the ramp support;
• and
• move along the first-ramp surface until the distal first-suspension-arm end intersects a first plane between the proximate first-suspension-arm end and a proximate second-suspension-arm end of a second read-write head assembly;
• and
• a second suspension arm of the second read-write head assembly to move toward and contact a second-ramp surface of a second ramp of the ramp support,
• wherein:
• the second suspension arm is co-movably fixed to the first carriage arm and has a second-suspension arm length extending from a proximate second-suspension arm end to a distal second-suspension arm end of the second suspension arm different from the first-suspension arm length.
