An abrasive tape having an abrasive layer primarily containing abrasive grains and a binder and formed on a flexible substrate and a member to be cleaned are fed in substantially opposite directions with the abrasive layer and a surface of the member kept in contact with each other with the ratio of the feed rate of the member to the feed rate of the abrasive tape kept not higher than 1/1.

Cleaning method using abrasive tape

An abrasive tape is disclosed, comprising a flexible support having thereon an abrasive layer containing mainly an abrasive particle and a binder resin, wherein said abrasive layer has a thickness of from 0.3 to 10.0 .mu.m, an interlayer is provided between said abrasive layer and said flexible support, the thickness of said interlayer is 1 .mu.m or more, 30% or more of the thickness of said flexible support and larger than the thickness of said abrasive layer, and said interlayer has a Young's modulus of from 10 to 150 Kg/mm.sup.2. The abrasive tape may be used for cleaning and polishing a magnetic head.

A surface of a member having intrinsic projections thereon is polished to remove the intrinsic projections. An abrasive tape is formed of a substrate and an abrasive layer formed thereon. The abrasive layer primarily contains abrasive grains and a binder. The abrasive tape and the member are slid in substantially opposite directions with the abrasive layer and the surface of the member kept in contact with each other.

Polishing method

In this computer system, a plurality of processing elements (PE), each having at least two channel processors which manage corresponding communication channels separately, are connected in a ring via the channel processors to form a processing element loop (10). Some of the processing elements are designated as process managers (SM.sub.1 -SM.sub.n) which manage the corresponding process frame groups (20) comprising a predetermined number of process frames. At least one other element is designated as a master manager (MM) which manages those process managers. The respective process managers (SM.sub.1 -SM.sub.n) each allocate a predetermined process to any one process frame of the process frame group (20) which that process manager manages in accordance with each requirement from the master manager (MM) to cause that process frame to execute the predetermined process. Thus both of the function and load decentralizing functions as a computer system are satisfied on the basis of the function of the master managers (SM.sub.1 -SM.sub.n) and process manager (MM).

A process for the preparation of a magnetic recording medium comprises the steps of subjecting a magnetic recording layer coated on a nonmagnetic support to surface smoothening treatment, said magnetic recording layer comprising a ferromagnetic powder dispersed in a binder, and then abrading a surface of the magnetic recording layer by means of an abrasive tape.

Process for the preparation of magnetic recording medium

A process for the preparation of a magnetic recording medium which comprises the steps of subjecting a magnetic recording layer coated on a nonmagnetic support to surface smoothening treatment, said magnetic recording layer comprising a ferromagnetic powder dispersed in a binder which is composed of a resin component and a curing agent, and then shaving a surface of said magnetic recording layer by means of a shaving device having high hardness.

A process for the preparation of a magnetic recording medium comprises the steps of subjecting a magnetic recording layer coated on a nonmagnetic support to surface smoothening treatment, the magnetic recording layer comprising a ferromagnetic powder dispersed in a binder, and then grinding both a surface of the magnetic recording layer and a surface of a back layer provided on the support using a specific grinder. The specific grinder is a fixed blade, a diamond wheel or a rotatable blade. A rotatable blade-grinder preferably employable for the grinding procedure comprises a rotatable body having a circular section and one or more blades provided on the periphery of the body.
