Abstract
The present magnetic recording and reproducing device is provided with a magnetic head ( ), which, during recording, applies an external magnetic field to a recording medium ( ) having a recording layer made of a ferrimagnetic material, and with a laser light source, which increases the temperature of the recording medium ( ) in domains (Tr and Tr ) which are opposite the magnetic head ( ), but exclude a track to be recorded (Tr), which is a domain for recording. Consequently, a magnetic recording and reproducing device can be provided which is capable of suppressing crosstalk and realizing higher recording density than conventionally.
