Problems solved by technology

At the same time, U disks and mobile hard disks have exposed USB interface electrical contacts, dust, high humidity, and small external forces may cause damage to them, and long-term storage on individuals will cause physical damage to the USB interface and directly affect the storage of data. Stability and Security
Although the Bluetooth U disk avoids the trouble and disadvantages of plugging and unplugging, its transmission speed is slower than ordinary U disks and mobile hard disks, which reduces work efficiency and high cost.

Abstract

The invention relates to a non-electrical-contact type portable memory and a read-write device, which are used for transmitting data between a computer and a memory. The technical proposal of the invention comprises that the non-electrical-contact type portable memory and the read-write device. The read-write device is connected with a USB interface of the computer through a data wire, uses an electromagnetic coil to supply power for the non-electrical-contact type portable memory, and performs data transmission with the non-electrical-contact type portable memory in a magnetic coupling, galvanic coupling or optical coupling mode without an electrical contact. The memory and the read-write device greatly increase the convenience of use and the durability of the memory, and provide the data transmission performance having the same speed with a universal portable memory namely a USB flash drive, can replace the mainstream USB flash drive products in markets at present, and have great economic benefit.

Description

Technical field: [0001] The invention relates to data exchange between a computer and an external memory in the electric communication technology. It is mainly suitable for individuals and units that need to frequently transmit data with computers, providing them with a high-speed, stable, easy-to-use, and durable data exchange tool. Background technique: [0002] In the current way of data exchange between computers and storage devices, commonly used portable memory U disks and slightly larger mobile hard disks are mainly used. What they have in common is to be directly connected to the USB interface of the computer. Often plug and unplug the USB interface; at present, a relatively new USB flash drive is also on the market, that is, a wireless USB flash drive, which transmits data through wireless bluetooth and other methods. The above are the three commonly used methods of data exchange and transmission at present. The first two are in direct contact with the computer. Co...
