摘要： An enlarged substrate for a magnetic recording medium used in a data storage device such as a hard disc drive (HDD). In some embodiments, a data storage device has a housing member for a 3½ inch form factor storage device or a 2½ inch form factor storage device. A rotatable data recording disc is supported by the housing member. The disc has a plurality of tracks formed thereon. At least one track of the plurality of tracks has an average radius of greater than 47.5 mm for the 3½ inch form factor storage device or greater than 32.5 mm for the 2½ inch form factor storage device. A data read/write transducer is configured to be controllably advanced across a recording surface of the data recording disc and to record data to the plurality of tracks.
