Title: Pcm signal recorder
Inventor: TANAKA HIROMICHI
IPC: G11B20/12
Filed: 1987-04-01
Abstract: PURPOSE:To perform the recording and reproduction with high quality of a voice, by providing a symbol generation circuit, an interleave circuit, an error correction code generation circuit, a block generation circuit, a frame generation circuit, and a code conversion circuit. CONSTITUTION:By sampling an input analog signal with a frequency of 48kHz, a digital signal with a unit of 16 bits can be obtained as the output of an ADC circuit 2. The signal is compressed to the one of 12 bits at a compression symbol generation circuit 3, and a symbol is generated setting 6 bits as one unit. Symbol information is distributed at the interleave circuit 5, and a processing to respond to a burst error at the time of recording and reproduction is performed. Simultaneously, a block is constituted at the block generation circuit with a synchronizing signal in the lead. A corrected code is attached at the error correction code generation circuit 6. An information frame is constituted of the block according to the cycle of a reference synchronizing signal, and code modulation is applied in a symbol unit, and a large amount of information can be recorded efficiently. Asynchronism between the symbol information and the reference synchronizing signal is controlled and absorbed with the quantity of the symbol information in the frame. By constituting a device in such way, it is possible to perform the recording with high density of the information on a limited area. Also, since independence from a video signal is realized, digital dubbing can be performed.

Title: Lubricant used for magnetic recording medium
Inventor: SUMIYA KAZUHIKO
IPC: G03G19/00
Filed: 1983-05-04
Abstract: PURPOSE:To prevent magnetic spacing and to obtain good high frequency record reproducing characteristics by dispersing ferromagnetic microparticles sufficiently smaller than bit length and thickness of a lubricant layer into the lubricant using a surfactant. CONSTITUTION:Ferromagnetic microparticles, such as 10-20nm particle diameter magnetite (FeO.Fe2O3), sufficiently smaller than the bit length and lubricant layer thickness are dispersed into a lubricant, such as fluorinated oil by using oleic acid. This lubricant is applied to a magnetic layer 14 to form a lubricant layer 113, and said microparticles are concentrated at the part facing the magnetization reversed parts of the layer 14. As a result, magnetic spacing between the end of a magnetic pole 11 and the layer 14 is buried when a signal magnetic pole type head 10 is brought into contact with its surface, and magnetic resistance is reduced.
