A disc drive production process automatically configures the disc drive to a suitable capacity based upon the data transfer capability of each of the head/disc surface combinations in the drive. The error rate of each of the head/disc surface combinations is determined as a function of the bit density of the disc surface. Based on the data transfer capability of the head/disc surface combinations, one of three drive configuration schemes is selected. A variable BPI (bits per inch) scheme reduces the data rate of a weak head/disc surface combination while increasing the data rate of a strong head/disc surface combination. If the drive contains one very weak head/disc surface combination, a head depopulation scheme disables the very weak head. If the drive contains two or more very weak heads, a de-frequency scheme reduces the overall capacity of the drive.
A method of configuring a disc drive having a plurality of read/write heads, each adapted to read and write data to one of a plurality of disc surfaces, comprising steps of:
A program storage device readable by a computer system tangibly embodying a program of instructions executable by the computer system to perform a method of configuring a disc drive having a plurality of read/write heads, each adapted to read and write data to one of a plurality of disc surfaces, the method comprising steps of:
A disc drive comprising:
