Abstract: This invention provides methods and compositions for reducing or eliminating undesired self condensation of ketone solvents in magnetic metal particle coating mixes used in the manufacture of magnetic recording media. The self condensation products, such as dimers, of ketone solvents, such as cyclohexanone, are reduced or eliminated by treating the magnetic metal particles with a combination of a dispersing agent and a fatty acid before placing the particles in contact with a ketone solvent used in forming a magnetic coating mix containing the magnetic metal particles. The resulting recording media have improved properties, reduced solvent retention, and reduced odor.

IPC: H04B15/00

Abstract: The circuitry is used in high-quality sound recording and playback systems. Even in these systems, the ground wires have a finite resistance. The currents flowing through them therefore generate voltages, albeit of a very low level. Potential differences thus occur over the length of the ground wires. This impairs playback. To cancel or at least minimise these potential differences, the invention provides that all ground wires have a lower specific resistance than the signal wires and the same resistance as one another.

Abstract: A system (30) for atomic access to an I/O device with DMA includes a CPU (32) connected to a floating point processor (FPU) (34) by bus (36). The CPU (32) is connected by a system bus (38) to a random access memory (RAM) (40), a cache (42) and an interface (44) in graphics subsystem (45). The interface (44) is connected by bus (46) to graphics processor (48). In this system, graphics subsystem (45) is an I/O device, and atomic access to it is required. Command packet interface (44) to the graphics subsystem (45) transfers geometry and graphics context information from main memory (40) to the graphics subsystem (45). For such transfers, an application writes a list of commands to a physically contiguous locked-down memory buffer (47) in its own address space. Since the system (30) has DMA, the buffer (47) resides in the main memory system (40). When the buffer (47) is full, the CPU (32) tells the graphics subsystem (45), via a read from an I/O address on the graphics subsystem (45), that it should begin a transfer of the command packet. Status of the operation is returned as a result of the I/O read transaction. After initiating the command packet transfer, the graphics subsystem (45) parses the packet and executes the appropriate operations atomically.

Abstract: A system is provided for controlling positions of record tracks relative to a scanning trace of a head device (12A;12B). An envelope detector (36) detects an envelope of an output from a head device (12A;12B) operative to scan a record tape (13) along a scanning path transverse to record tracks. A pulse generator (40) produces two pulses appearing respectively at predetermined time points in a period of a scanning trace of the head device (12A;12B). A level sampler (37) samples a level of a detection output from the envelope detector (36) with the pulses produced by the pulse generator (40) to produce two sampled outputs. A dislocation detector (41) detects dislocation of a group of record tracks traversed by the head device (12A;12B) relative to the scanning trace of the head device (12A;12B) based on a difference between the sampled outputs from the level sampler (37). A tape controller (42,45) adjusts a travelling speed of the record tape (13) to control positions of the record tracks traversed by the head device (12A;12B) relative to the scanning trace of the head device (12A;12B) in response to a detection output from the dislocation detecting circuit (41).
