网络技术已渗透到社会生活的每一个角落。WWW的出现产生了HTML。在WWW中发布HTML文档,大多数信息还是静态的,而且要求服务器响应用户的交互。后来出现了DHTML语言。虚拟现实是计算机模拟的三维环境,用户可以走进这个环境并操纵系统中的对象。虚拟现实最重要也是最诱人之处是其实时性和交互性,这样出现了VRML语言。电子商务在互联网的广泛应用又产生了XML。网络继续以很快的速度在发展,将来的网络会以比现在的网络文档更灵活的方式提供更多的信息。  相似文献

街角     
北方初春的早晨。昨晚下了一场雨加雪,地面变得湿滑不堪。 在一个十字路口发生了一起车祸。一辆装着废品的三轮车为了冲过一个红灯加速行驶,与路口驶来的一辆转向的出租车发生了碰撞。由于地面湿滑,刹车不及,三轮车司机被重重地摔飞出去数米远。一动不动的趴在地上,看样子受伤非常严重。他收来的废品因为三轮车的侧倾而散落出来,铺满了半条街面。  相似文献

正俄罗斯正在研制新一代潜艇主动隐形材料。该消息得到了圣彼得堡克雷洛夫院士中央科研所的证实。相关工作正由该科研机构负责。据俄罗斯《消息报》近日报道,潜艇隐形目前主要依靠所谓的被动反声呐涂层。涂层的主要材质是橡胶。但覆盖这种涂层的潜艇在频率低于1千赫兹的声呐面前仍然无所遁形。  相似文献

随着社会的进步,信息技术的发展,移动接收成为发展方向之一。比如移动电话,它现在的普及程度已经不低于固定电话。广播电视虽然有很长的历史,但移动接收的进展却不尽人意。即使是调频广播,在汽车高速行驶中的接收也往往遇到困难。所以广播电视的移动接收引起广电界的重视。  相似文献

提到武夷岩茶,很多人会混淆它的概念。武夷岩茶不是单一的一种茶的名字,是一类茶的总称。这类茶有多少个品种,从古到今不下干种。常见的有二百多个品种。这其中,最出名是大红袍。武夷岩茶根据茶树所处的位置,分成三大类:正岩茶、半岩茶、洲茶。正岩茶指武夷岩中心地带所产的茶叶。半岩茶指武夷岩边缘地带所产的茶叶,其岩韵略逊于正岩茶。洲茶泛指崇溪、九曲溪、黄柏溪溪边靠武夷岩两岸所产的茶叶。武夷岩茶  相似文献

一、品牌的情感特点 香烟是消费品,体现使用价值。人们抽根香烟,不仅仅是为了满足感官这么简单。卷烟是有品牌的,品牌是可以有感情的。当消费者抽另一种牌子的烟时,他已经与所抽牌子的烟产生了情感。而且是品牌自身所具有的情感。  相似文献

The lubrication of head / disk interlaces in magnetic hard disk drives by physically processed thin films was investigated. Sputtered gold films showed no useful endurance as a protective / lubricating film. Ion-plated carbon films and hydrogenerated carbon films (i-carbon) were effective for preventing tribological damages in magnetic recording media, while amorphous carbon films (a-carbon) were ineffective. The longest durability was found for i-carbons. Raman scattering showed that i-carbons contained much sp3 component, and microindentation test signified that i-carbon films were twice as hard as amorphous carbon films. As a protective film, i-carbon seems very promising, but hard materials should be selected as heads to avoid quick wear of the head. Sufficient performance of i-carbon films may lead to application of thin solid lubricants to hard disk drives.  相似文献

超薄磁盘保护膜的制备技术   总被引:1,自引:0,他引:1  
类金刚石薄膜和氮化硅薄膜都是性能很好的绝缘材料,可以用于对磁盘进行保护,在本文中主要讨论了它们各自的制备方法.随着巨磁阻读写磁头(giant magneto-resistive heads)技术的引入,磁盘的存储密度以每年100%的速度在增加,这就要求磁盘保护膜的厚度要尽量的小,所以对制备方法有一定的要求.对类金刚石磁盘保护膜,可以使用等离子体磁控溅射沉积、磁过滤阴极弧沉积、等离子体化学气相沉积来制备;对氮化硅磁盘保护膜,可以使用射频反应溅射沉积来制备.  相似文献

The mechanical properties of ultra‐thin amorphous carbon films used as protective coatings for magnetic storage devices were investigated by means of atomic force microscopy (AFM). Diamond‐tipped cantilevers were used in order to generate scratches with residual scratch depths of only a few Angstroms and even below. The presented method simulates mechanical strains at the head‐disk interface. A driftcompensating image subtracting technique allows the visualisation of these ultra‐shallow scratches and enables the mechanical characterisation of only few Nanometer films widely independent from the hardness of the substrate. The scratch resistance as it is defined here correlates well with the mass density and the sp3 content of the investigated films.  相似文献

Humidity influences the tribological performance of the head-disk interface in magnetic data storage devices. In this work we compare the uptake of water of amorphous hydrogenated carbon (a-CHy) and carbon nitride (a-CNx) films, widely used as protective overcoats in computer disk drive systems, with two types of amorphous non-hydrogenated carbon (a-C and a-Csp2) films, and fullerene-like carbon nitride (FL-CNx) films. Carbon films were deposited on quartz crystal substrates by reactive dc magnetron sputtering in Ar/N2 discharges. After deposition, some of the films were coated with a 2-nm-thick layer of Z-tetraol, a lubricant used in hard disk devices. A quartz crystal microbalance placed in a vacuum chamber was used to measure the adsorption of water at room temperature and at pressures of water corresponding to relative humidities in the range RH = 0 to 90%. Water adsorption and desorption is fast, indicating that equilibrium with ambient humidity is reached on time scales of minutes, much faster than the time scales for fluctuations in ambient humidity. The amount of water adsorbed on the non-lubricated amorphous carbon films is significantly higher than that on the fullerene-like films. The presence of the lubricant influences water adsorption but its impact differs on different carbon films.  相似文献

A volumetric optical disk that has multiple transparent films with optical switching layers is used as a recording medium to increase the number of recording layers. In the disk the optical switching layer is adapted to reduce decay of laser energy and increase reading and recording sensitivity. Well-defined marks of approximately 100-nm depth can be placed precisely on the transparent films by a focused laser beam. Writing and reading of a four-layer recordable disk, fabricated by molding and spin bonding, have been demonstrated experimentally. The volumetric disk can achieve a high recording capacity with conventional optical pickups.  相似文献

Blue/DVD/CD compatible optical head   总被引:1,自引:0,他引:1  
Katayama R  Komatsu Y 《Applied optics》2008,47(22):4045-4054
Compatibility with Digital Versatile Disc and Compact Disc has been demonstrated for two options of high-density optical disk systems using a blue laser diode. Option 1 (HD DVD) employs a 0.65 numerical aperture objective lens and a 0.6 mm thick protective layer disk, while Option 2 (Blu-ray Disc) employs a 0.85 numerical aperture objective lens and a 0.1 mm thick protective layer disk. An optical head has three laser diodes whose wavelengths are 405 nm, 660 nm, and 785 nm. A spherical aberration caused by the difference in the protective layer thickness of the disk is corrected by an objective lens magnification change, while the numerical aperture of the objective lens is controlled by a wavelength-selective aperture. Experimental results have shown that Option 1 is more preferable, but Option 2 is also acceptable from the viewpoint of the compatibility.  相似文献

An optical contour mapping with a laser-interference method was carried out to evaluate the topographical deformation of optical memory disks. The dynamics of the deformation in a manufacturing process was studied. Reflective films and a protective resin coating increased the dishing, irrespective of the original shape of a substrate. A bonding process decreased the dishing and contributed to mechanical stability that lasted for a long period in daily use. In the case of a 0.6-mm-thick substrate, as with a DVD disk, the large dishing of the single substrate was suppressed by the bonding to less than 100 mum. In addition, it was shown that distortions arising from the molding process remained in the final product and that the initial process should be carefully controlled.  相似文献

The paper deals with analysis of morphology and electrical properties of (nano)composite films. It describes a computer simulation tool for morphological and transport analysis of the films. Two models of composite structures are prepared — a hard disk and soft disk model. Their morphology is studied by the covariance, Quadrat Counts method, and Voronoi tessellation. Some specific characteristics of the methods are introduced. The electric properties are studied by the Monte Carlo simulations via tunnel charge transport. The results for d.c. conductivity as well as in case of changing voltage are done.  相似文献

Due to the lateral size reduction of stored bits on a hard disk, the head‐to‐media spacing has to be reduced as well as the thickness of the protecting carbon overcoats. In order to obtain a thickness in the 2 nm region a new process technology is needed. In the present paper, a high current pulsed arc (HCA) technique is presented as an innovative source for ultra thin carbon coating for future industrial disk production. The hardness and scratching resistance of these films are remarkable higher than conventional magnetron sputtered films. With the HCA‐Source we are able to produce pinhole‐free carbon films with thicknesses down to 2 nm. The deposition rate is 0.07 – 0.3 nm per pulse, therefore the coating time is below 2 sec per disk. The magnetic layer is left undamaged during the HCA deposition process. These aspects are very important for industrial disk production efficiency. Strong particle reduction due to a magnetic filter tube is confirmed by repeatable glide tests. Particles are confined in the magnetic filter tube and do not reach the substrate. In several important tests we showed that the HCA source is capable of producing carbon layers within a realistic disk production environment with a yield over 90 % which proved to be comparable to current magnetron sputtered overcoats.  相似文献
