Abstract: A wheel cleaning cover, such as for a golf trolley wheel, is formed of a pair of hinged circular covers, each forming a semi-circular half and made of a light, robust material. When the golf trolley is not in use, a pair of such wheel covers can be closed around respective ones of the golf trolley's wheels. For each such wheel, the hinged semi-circular halves are securely fastened to one another to encase the associated wheel therewithin. The trolley wheels can remain on their axle(s) while the covers are securely closed around the wheels.

Abstract: A read/write magnetic head assembly includes an inductive write head and a magnetoresistive (MR) read head. The inductive write head includes first and second magnetic poles, P1 and P2 respectively, which form a magnetic circuit with a write transducing gap.
