A propeller-enclosed airlifting air tube apparatus contains a unique multi air-tube structure that functions as a plurality of air outtakes to produce stable lift force with one or more propellers enclosed in the apparatus. By encapsulating the propellers within the outer shells, the airlifting air tube apparatus is able to reduce potential bodily harm and property damage risks during a flight operation in a densely-populated environment or in another environment involving tight spaces. The airlifting air tube apparatus encapsulates one or more pairs of contra-rotating propellers inside a drone casing to enhance operational safety while minimizing the overall footprint of the apparatus. Furthermore, the airlifting air tube apparatus incorporates a novel airflow control dish-based flight control steering unit configured to change directions and altitudes of the apparatus by dynamically adjusting the airflow to each outtake air tube with the airflow control dish.

A hard disk drive that utilizes a third order curve fit equation to generate a skew table for a head of a hard disk drive. The skew table is used to compensate for offset between a write element and a read element of the head at different radial positions of a disk. A linear algebraic matrix equation can be used to solve the third order equation using offset values measured at different radial positions of the disk.
