摘要:
A method and apparatus for increasing the capacity of magnetic media storage is disclosed. More specifically, an improved two-sided magnetic tape is disclosed. In one implementation, in order to mitigate pack winding problems, a trade-off can be made between the back-coat roughness of a side of the magnetic tape and the mechanical imprint of that roughness in the recording surface of that side (e.g., compromise between roughness and recording density). For example, a recording density and coding scheme deemed appropriate for a relatively large recording head-to-media separation can be used for the “rougher” side of a two-sided tape, and the highest recording density achievable can be used for the “best” or smoothest side of the two-sided tape. Depending on the recording density/roughness match selected, an optimum capacity gain can be selected from a range of capacity gains with values between 1 and 2 (e.g., 1
