Abstract:
A magneto-optical (MO) disk drive. In one embodiment, the MO disk drive comprises a drive controller that controls operation of a laser source and a disk drive mechanism. The drive controller comprises a microprocessor and a memory subsystem coupled to the microprocessor. The memory subsystem comprises a memory device that stores programs directing operation of the disk drive and information used by the programs during operation of the disk drive. The stored information comprises an identifier that matches an identifier of a magnetic medium. The stored information also comprises a set of constant values characteristic of physical properties of the magnetic medium denoted by the letters h, k, s, c,. alpha. ,. beta. and. delta. The stored information also comprises a set of equations that determine optimum write powers as a function of linear velocity, v, of the magnetic medium. The equations include: Ph(v)=hv. sup. alpha.
