Method of writing data on a storage device using a probe technique

Abstract

Provided is a method of writing data on a storage device using a probe technique. In the method of writing data on a memory device including a resistive probe used for reading and writing of data, a ferroelectric writing medium on which data is written by the resistive probe, and a lower electrode disposed on a bottom surface of the ferroelectric writing medium, a heat and electric field are applied at the same time to a domain of the ferroelectric writing medium, on which the data will be written, by applying a voltage to the resistive probe and the lower electrode.

Description

technical field [0001] The invention relates to a method for writing data, in particular to a method for writing data on a ferroelectric layer by using a resistive probe. Background technique [0002] With the development of Internet-related technologies, writing media capable of writing a large amount of data including moving images (hereinafter referred to as "high-density writing media") and writing media for writing data on writing media and reading written data Portable devices, as important products in the writing media market, have received considerable attention in recent stages. [0003] The portable non-volatile data writing device can be classified into a solid-state storage device like a flash memory, or a magnetic disk type storage device like a hard disk. [0004] It can be expected that within a few years, the demand for basic capacity of handheld devices will reach the level of tens of gigabytes of capacity. For solid-state storage devices, it is conceivabl...

Problems solved by technology

However, the coils used to generate the magnetic field and the laser diodes used for heating cannot be placed in the same space

In addition, due to the narrow gap between the magnetic write head and the writing medium, it is almost impossible to apply a magnetic field and heat at the same time
