High capacity, low profile disk drive system

A disk drive assembly comprising:

• a three dimensional enclosure having a lateral form factor area defined between two side walls of the enclosure and a first end and a second end of the enclosure and a vertical thickness;
• a seal disposed within the enclosure, the seal defining a sealed volume and a circuit volume outside the sealed volume and within the enclosure;
• at least one disk disposed inside said sealed volume, said disk being rotatable in a plane;
• a disk spindle motor to rotate said at least one disk;
• a transducing head for transducing data from said at least one disk;
• a head actuator assembly disposed inside said enclosure at said first end of said enclosure;
• a printed circuit board assembly removably mounted in said circuit volume, in a plane substantially parallel to said plane in which said at least one disk is rotatable and adjacent laterally to said head actuator assembly at said first end of said enclosure and further wherein a top of said enclosure completely covers the printed circuit board assembly;
• electronics controlling said head actuator, said spindle motor and controlling the flow of data from said transducing head, said electronics mounted in close proximity in substantially the same plane on said printed circuit board assembly;
• a first connector connecting said electronics on said printed circuit board assembly to said transducing head and said actuator assembly;
• and
• a second connector mounted on said printed circuit board assembly along the first end opposite from the at least one disk and matable with a connector exterior to said disk drive assembly.
