IPC: G11B7/00
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical disk device and its adjusting method capable of efficiently and maximally adjusting a recording power margin. SOLUTION: A signal is recorded in varying a laser output in an address A of a reference disk by using an adjusted disk device, and is reprodued, and hence reference recording is performed with an output smaller than an upper limit value of the laser output to fall within an error correctable error rate range. The upper limit value is greatly dependent upon a characteristic of an equalizer (ST1-3). The address A of the reference recorded disk is reproduced in controlling a gain of an equalizer of a nonadjusted disk device to obtain an upper limit and a lower limit to be of the error correctable error rate range, and the gain is controlled to a central value of this range (ST4-5).  A signal is recorded in changing the laser output in an address B of the disk, and is reproduced to obtain an upper limit and a lower limit to be of the error correctable error rate range, and the laser output is adjusted in view of a variation and a secular change (ST6-7). An adjusting process and the limit values are stored in a memory so that the adjustment can automatically be performed.
