Abstract
A hard disc drive (HDD) with an enlarged magnetic recording disc. In some embodiments, a base deck and top cover are arranged to provide an HDD housing with a 2½ inch form factor or a 3½ inch form factor. A magnetic recording disc is supported for rotation within the housing. A data transducer is controllably advanced across a recording surface of the magnetic recording disc to write data to the recording surface, and a printed circuit board assembly (PCBA) affixed to an external surface of the base deck incorporates control electronics to provide write signals to the data transducer during the writing of data to the recording surface. The disc has an outer diameter of at least 67 millimeters, mm for the 2½ inch form factor housing and has an outer diameter of at least 97 mm for the 3½ inch form factor housing.
