Abstract

Disclosed are a magnetic recording method and a magnetic recording device. The magnetic recording method comprises: acquiring a write bit density and the step size and speed of a step motor; calculating a step interval time according to the step size and speed of the step motor, wherein the step interval time is the time which is taken by the step motor to carry out one step; calculating a bit interval time according to the write bit density and the speed of the step motor, wherein the bit interval time is the time which is taken by a magnetic head to record one bit of binary write data; and controlling the step motor to drive a magnetic medium to move with the step interval time as a period, and controlling the magnetic head to write with the bit interval time as a period. The present invention improves the adjustment flexibility of a write bit density.

Description

technical field [0001] The invention relates to the field of magnetic recording, in particular to a magnetic recording method and a magnetic recording device. Background technique [0002] At present, magnetic recording devices have been widely used in fields such as banks, railways, aviation, and exhibitions to record magnetic information in magnetic tracks of magnetic media such as passbooks, magnetic tickets, and magnetic cards. The recording of magnetic information (hereinafter referred to as magnetic recording) is to record binary data in the magnetic track according to the change of magnetic flux reversal. Among them, the number of bits of binary data stored on the unit length of the track is called bit density, and its unit is usually bit / inch ( Abbreviated as bpi,) means that the greater the bit density, the greater the amount of magnetic information recorded in a fixed-length track. [0003] With the application of magnetic recording devices more and more widely, t...
