A magnetic disk drive unit can is designed for reducing weight, improving impact resistance, improving removing ability, and achieving easiness of assembling and lower a cost in a magnetic disk drive unit. The magnetic disk drive unit includes a spindle motor mounting a magnetic disk, a carriage mounting a magnetic head for recording and reproduction, a park mechanism for placing the magnetic head retracted from the magnetic disk at stand-by state where recording and reproducing are not performed, a single rigid frame mounting the spindle motor, the carriage and the park mechanism thereon for forming an assembly, and a casing housing and fixing the assembly, the casing being formed of an elastically deformable material.
