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.

Abstract: An enlarged substrate configuration for magnetic recording media. In some embodiments, an apparatus comprises a disc shaped member of metal or glass configured as a substrate for a magnetic data recording disc for a 2½ inch form factor data storage device or a 3½ inch form factor data storage device. The disc shaped member has a top planar surface, an opposing bottom planar surface, an outermost annular sidewall that extends between the top planar surface and the bottom planar surface at an outermost diameter of nominally 67 or 97 millimeters, respectively, and an inner annular sidewall that extends between the top planar surface and the bottom planar surface to define a central aperture.
