摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric crystal actuator and a technique for reduction in hysteresis.
SOLUTION: This invention proposes the use of a piezoelectric crystal element as an actuator for data storage systems. In particular, the piezoelectric crystal element mechanically positions a head with respect to data storage medium. More specifically, the present invention may use a piezoelectric laminate crystal structure as a fine positioning actuator in a magnetic tape system, in order to precisely position one or more heads with respect to tracks of the magnetic tape. Furthermore, in order to cope with hysteresis in the piezoelectric crystal element, introduction of a high-frequency periodic signal is introduced as a part of the input to the piezoelectric crystal element.

摘要： PROBLEM TO BE SOLVED: To provide a method for adjusting actuator nonlinearity inside a data storage system.
SOLUTION: The method for adjusting the actuator nonlinearity inside the data storage system is provided. This method is useful to a piezoelectric actuator, especially to the actuator implemented with, for example, bimorph piezoelectric crystal structure or the laminated piezoelectric crystal structure, but there are instances in which a similar nonlinearity problem is raised by the other actuators. In one embodiment, the method includes a step for impressing a signal, including a linear driving component and nonlinear adjusting component, to the actuator having nonlinear response for the data storage system, and a step for positioning the data storage head to the data storage medium by the actuator.

摘要： PROBLEM TO BE SOLVED: To provide a system including a write head matrix array and a magneto-resistance (MR) read head matrix array. SOLUTION: In the system equipped with the nonlinear array of magneto-resistance heads arrayed in a two-dimensional matrix for reading information stored in a magnetic medium, the nonlinear array of the MR heads is provided with a planar array constituted of a plurality of linear arrays of MR heads stacked to define a plurality of layers. Each linear array shares at least one shield element with the other linear array of the nonlinear array. Generally, each layer is shifted by one writing pitch, and the number of layers is equal to the number of writing pitches. This matrix array is used in a system for reading/writing information in a magnetic medium by a track pitch improved as compared with a conventional reading/writing system.

摘要： The invention is directed to a data storage medium that includes a plurality of servo bands distributed across the data storage medium and a plurality of data tracks positioned between each of the plurality of distributed servo bands. The data storage medium comprises a servo band pitch of less than 200 micrometers. The large number of servo bands distributed across the data storage medium with a relatively small servo band pitch reduces the influence of media dimensional instability. In this way, the invention may substantially increase data read head positioning accuracy, especially in the case of narrow track widths. A read head array arranged in a two-dimensional matrix that includes a first servo read head, a second servo read head, and a plurality of data read heads positioned between the first and second servo read heads may be applied to a data storage medium as described herein.
摘要翻译：本发明涉及一种数据存储介质，其包括分布在数据存储介质上的多个伺服带和位于多个分布式伺服带中的每一个之间的多个数据磁道。数据存储介质包括小于200微米的伺服带间距。分布在具有相对小的伺服频带节距的数据存储介质上的大量伺服频带减少了介质尺寸不稳定性的影响。以这种方式，本发明可以显着增加数据读取头定位精度，特别是在窄轨道宽度的情况下。布置在包括第一伺服读取头，第二伺服读取头和位于第一和第二伺服读取头之间的多个数据读取头的二维矩阵中的读取头阵列可以作为在此描述。

摘要： PROBLEM TO BE SOLVED: To provide a means for effectively preventing the irregular winding of a tape. SOLUTION: A data recording tape is passed through a reading/writing head along guide. A sensor detects the position of the tape, and adjusts the guide and the head as the function of the position. When the tape is shifted from a target tape route, a controller moves the guide to return the tape to the target tape route by using a sensor signal. When irregular tape winding such as sudden tape movement occurs, in order to predict the specified position of the tape when the irregular winding reaches the head, an adaptation estimator positions the head by using the sensor signal.
