To store data is to store information in various forms. Data store is a collection of data that a repository persistently stores and manages, including not only things like warehouse databases, but also simple storage types such as simple files, E-mail, and so on. 

With high precision and stability, CoreMorrow piezo nano-positioning stage has a wide range of applications in data storage. In the field of data storage, piezo nanopositioning stages are often needed to achieve motion control accuracy at nanometer or even subnanometer level.

Piezo Nano-positioning Stage Applied to High Precision Adjustment of Read/Write Head

Piezo nanopositioning stage can be used for high density data storage and reading in optical disk data storage. The piezo nano-positioning stage is a kind of nano-level mechanical adjustment system, which is composed of piezo ceramics and nano-mechanical components, and can realize the position adjustment of nano-level. In optical disk data storage, piezo nanopositioning stage can be used to adjust the position of optical read/write head to improve the accuracy and capacity of data storage and reading. 

In the traditional magnetic hard disk, the read head needs to constantly seek and locate. The precise positioning and fast seeking of the read head can be realized by the fine adjustment of the piezo nano-positioning stage, which improves the speed and efficiency of data reading and greatly reduces the error of data reading.

CoreMorrow piezo scanning stage below can be used for 1 to 6 axis nano positioning.

Piezo Nanopositioning Stage Realizes Faster Data Reading Speed

In order to achieve higher reading and writing accuracy, the piezo nano-positioning stage can adjust the optical reading and writing head slightly. At the same time, the displacement of nanomechanical parts can be controlled quickly and precisely by the electric field action of piezo ceramics, thus realizing faster data reading speed. Research has shown that data storage densities of up to 10 terabytes /squareinch can be achieved using piezo nanopositioning stations, which cannot be matched by traditional optical storage technologies.

The product below is a preloaded piezo actuator by CoreMorrow, it can generate linear motion and responds in milliseconds.

Piezoe Nanopositioning Stage Improves Data Storage Density and Reliability

In addition, piezo nanopositioning stages can improve the density and reliability of data storage in non-volatile storage devices. In solid-state drives and flash memory devices, piezo nanopositioning stages can control the precise position of the storage unit, greatly improve the density of the storage unit, and reduce the error rate of data storage.

Below is one of CoreMorrow piezo nanopositioning stages, which can freely choose 1 to 6 axis movement, precision is up to nanometer level.

Piezo Nano-positioning Stage Realizes the Accurate Positioning of Laser Beam

The piezo nano-positioning stage is a high-precision nano-positioning tool, which can realize the positioning and accurate movement of objects at nanometer level. In laser data storage, piezo nanopositioning stage can be used to achieve accurate positioning of laser beam so that data can be accurately written into the storage medium.

Specifically, laser data storage is a high-density data storage scheme based on laser technology, which uses laser beams to form tiny pits and bumps on the storage medium to represent binary data. In this process, the piezo nanopositioning stage can control the precise position and direction of the laser beam to ensure the accurate writing of data.

Laser data storage needs to control the focus size of the laser beam in a very small range in order to achieve high density information storage. To achieve this, a high numerical aperture object lens is used and the numerical aperture is increased by multiple stacking, to further improve the quality of focus. Generally speaking, the larger the weight of the object lens, the larger the numerical aperture and the better the focusing quality, but the correspondingly higher the cost. This requires the piezonano-positioning stage to have a high bearing capacity.

The Piezo Objective Scanner below can be used for Z focusing with accuracy up to nanometers. The load capacity of the piezo objective scanner can be more than 500g.

Piezo Nanopositioning Stage is Used to Read Data Quickly and Accurately

In addition, piezo nanopositioning stages can be used to quickly read data on storage media. By focusing the laser beam on a specific location of the storage medium and controlling the movement of the laser beam with a piezo nano-positioning stage, the data can be read quickly and accurately.

The following is CoreMorrow piezo screw driver with travel range up to centimeters, suitable for large range, high precision position adjustment.

In addition, if the system needs, CoreMorrow piezo tip/tilt platform can be used to adjust the steering of the beam. With a range of up to 43mrad and a fast response of millisecond order, CoreMorrow piezo tip/tilt platform has been used on several satellites with very reliable performance.

CoreMorrow piezo tip/tilt platform is as below.

Piezo ceramics are used for magnetic head vibration detection and active vibration suppression.

With the increase of disk speed and storage density in computer hard disk, the positioning accuracy and seek speed of read/write head are required to be higher. But the wind disturbance driven by the high speed rotation of the platter will cause the vibration of the cantilever structure of the magnetic head, which directly affects its positioning accuracy and speed.

By using the CoreMorrow PZT piezoelectric ceramic plate as the sensor and driver, the active control of the vibration of the magnetic head suspension structure is realized.

CoreMorrow piezo ceramic sheetis as below, which can be as small as 2×2×2mm^3.

The selection of piezo nanopositioning stagess in the above data storage is only some cases. In data storage, motion dimension, stroke, accuracy, open/closed loop version, load capacity  should be selected according to specific system requirements. CoreMorrow piezo nano-positioning platform moving from one to six axes, has the characteristics of high precision, high stability, fast response, low temperature magnetism, etc., which can maintain stability under the operating conditions of high speed and high precision, and prevent interference and error. To sum up, piezo nano-positioning platform/piezoelectric ceramics, as a high-precision and high-speed mechanical motion system, they can bring more excellent performance for data storage and have a wide range of application prospects in data storage, which greatly improves the speed of data reading, storage density and reliability, and provide important technical support for data storage and processing.
