High density information storage medium

The invention is a kind of high-density information storing media, the invention upgrades the data density of unit area through decreasing the material area which represents the 1 bit, in order to increase the data storing capacity in unit area of information storing media; the invention increases the data storing density of unit area and the capacity through increasing the density of data tracks(namely reducing the interval of tracks) and reducing the data bit length of the stored of data tracks (namely reducing the interval of tracks) and reducing the data bit length of the stored information. The invention can produce high density CD disk with current equipment, at the same time, the invention can match with current optical lens to read the high density CD disk. 本发明是一种高密度信息存储媒体，本发明通过缩小代表1位(bit)的物质面积来提高单位面积的数据密度，以增加信息存储媒体单位面积的数据存储量；本发明的高密度信息存储媒体是通过增加数据轨的密度(即减少数据轨间距)以及减少存储信息的数据位长度的方法，以增加单位面积的数据存储密度并提升其容量；本发明可应用现有的生产设备来制造高密度光盘片，同时本发明更可配合目前的光学读写头来对高密度光盘片进行读写的动作。
