Title: Optical recording medium driving apparatus
Inventor: MATOBA HIROTSUGU
IPC: G11B7/085
Filed: 1992-07-30
Abstract: The optical recording medium driving apparatus has a first high-pass filter (22) for outputting a low frequency component removed signal by removing a low frequency component from a reproduction signal varying depending on a reflected light beam from the optical recording medium (1). The low frequency component removed signal changes due to transient response just after an access operation starts. Zero voltage is input to a second high-pass filter (28) during a tracking operation while a voltage having a negative polarity which is substantially the same amplitude as the AC component of the low frequency component removed signal is input to the second high-pass filter (28). The first high-pass filter (22) has the same time constant as the second high-pass filter (28). Just after the access operation starts, the negative voltage has the same transient response as the output of the first high-pass filter (22). The output of the first high-pass filter (22) is compared to the output of the second high-pass filter (28) in order to have a binary signal of a binary logic condition. A land is discriminated from a groove according to the binary signal, thereby enabling accurate access to a target track.

Abstract: A property of the hearing system, i.e. masking effect, can be utilized, as is known in the art, so that to any audio signal a second, weaker signal can be added inaudibly. In a system of prior art employing said principle an analysis of the audio signal and calculation of the masking threshold are carried out both in the transmitter and the receiver. This operation results in a complicated decoder and on certain occasions, audible distortion in a repeated audio signal. According to the present invention this can be so avoided that the transmitter transmits all data required in decoding on a separate data channel. Hereby, the decoder operates under the control of the transmitter.

Abstract: A multiprocessor (MP) computer sytem which allows target CPU(s) to continue processing instructions while other target CPU(s) are processing instructions of emulation code to reach their end of a Domain Unit of Operation before synchronization. A two-level MP sync is used since the target CPUs must be in between units of operation when the updates occur since a unit of operation can be one instruction or it can be many instructions that together emulate one instruction. Two level MP sync allows CPUs that are going to be serialized to continue to process single instructions (no emulation code) while other target CPUs are in emulation mode.
