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.

摘要： 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.

摘要： A data storage device having a housing member for a selected one of a 3½ inch form factor hard disc drive (HDD) or a 2½ inch form factor HDD. A spindle motor coupled to the housing member supports a rotatable data recording disc with a plurality of data tracks and an outermost perimeter. The outermost perimeter has an average overall radius of 48.5 millimeters, mm responsive to the housing member being for a 3½ inch form factor HDD or an average overall radius of 33.5 mm responsive to the housing member being for a 2½ inch form factor HDD. The rotatable data recording disc further has an outermost data track at an average selected radius such that the difference between the average overall radius of the outermost perimeter and the average selected radius is more than 1 mm.

摘要： 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.

摘要： A method includes forming, by a laser beam supplied by a laser cutting system, a laser-cut line in each of a plurality of glass samples. Each different laser-cut line in each different glass sample of the plurality of glass samples is formed when the laser cutting system is at a different process setting. The method also includes subjecting each of the plurality of glass samples with the laser-cut lines to a break test, and obtaining a plurality of break strength values. Each different break strength value of the plurality of break strength values is indicative of a laser-cut line quality of the respective glass sample of the plurality of glass samples.
