Abstract
This invention includes a carnage assembly for carrying read/write heads into engagement with a recording medium. The carriage assembly comprises a carriage body formed from molded plastic. The body defines a sidewall having a first open end and a second open end with a passage extending therebetween. A coil is interlockingly coupled with the carriage body sidewall by being molded to carriage body. At least one carnage arm for carrying at least one head is interlockingly coupled with the carriage body sidewall by being molded to the carnage body.

A method of making a carriage assembly for a disk drive comprising:
- positioning a coil around at least one coil retaining member of a mold;
- positioning a bearing on a pin within the mold;
- positioning a first carriage arm within a first slot within the mold;
- injecting a material into a mold cavity within the mold such that the material flows underneath the coil, around the first carriage arm and the first bearing and into the mold cavity to form an in rigger;
- and
- hardening the injected material form a carriage that includes the in rigger and wherein the carriage is molded to the coil, the first carriage arm and the first bearing to form the carriage assembly.
A method of making a carriage assembly for a linear actuator of a disk drive comprising:
- positioning a coil around at least one coil retaining member of a mold;
- positioning a bearing on a pin within the mold;
- positioning a first carriage arm within a first slot within the mold;
- injecting a plastic material into a mold cavity within the mold such that the material flows underneath the coil, around the first carriage arm and the first bearing, into the mold cavity to form an in rigger and around the pin to form a passageway;
- and
- hardening the injected plastic material to from a carriage that includes the in rigger and that has the passageway, that can receive a central guide track upon which the carriage can ride when inserted into the disk drive, and wherein the carriage is molded to the coil, the first carriage arm and the first bearing to form the carriage assembly.
