Abstract:
PROBLEM TO BE SOLVED: To carry out encoding by using a code conversion table in which parities of code sequences are different until the time when code states become identical. SOLUTION: The code word allocation of the code conversion table is carried out such that the code word binding length of decoding time is 3 blocks and q 0 ≠q 1 is satisfied for an optional information sequence no matter which position of the first and second bits of an information word the insertion position of a DC control bit is inserted. For example, when information sequences d 0 and d 1 having temporary DC control bits 1 and 0 inserted into the head of an information sequence [1, 1, 0, 0, 0, 1, 0] are encoded by using a predetermined code conversion table with a state 3 set as a starting point, code states s 0 and s 1 become equal at s 0 =s 1 =6 at the third block, and the compliments q 0 and q 1 of 2 of totals of code sequences c 0 and c 1 until the time when the code states become equal are respectively 0 and 1, thereby establishing q 0 ≠q 1 . The invention is applicable to a recording/reproducing device or an encoding device. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To perform encoding by using a code conversion table such that the parities of code sequences are up to the time point where the codes became identical are different. SOLUTION: According to the codeword allocation in the code conversion table, the constraint length of the codeword at the time of decoding is three blocks and a relation q 0 ≠q 1 is satisfied for an arbitrary information sequence by inserting a DC control bit in any of the first bit and the second bit of an information word. For example, an information sequence d 0 and an information sequence d 1 which are formed by respectively inserting temporary DC control bits 1 and 0 at the head of an information sequence [1,1,0,0,0,1,0] are encoded by using a predetermined code conversion table. In this case, an encoding state s 0 and an encoding state s 1 , when the state 3 is the start point, become identical at the third block: s 0 =s 1 =6. Since two's complement q 0 of the total of a code sequence c 0 until the codes become identical is 0 and two's complement q 1 of the total of the code sequence c 1 is 1, the relation q 0 ≠q 1 is satisfied. The method can be applied to a recording and reproducing device or an encoding device. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To reduce the number of conversion code words necessary for codes other than an 8/10 conversion DC free code. SOLUTION: This code division method combines together a 7/8 conversion DC free code and a 9/10 conversion DC free code, for example, which are independent of each other to obtain a 16/18 conversion DC free code. Thus, two independent codes are combined together into a fixed length conversion code. In this case, the start/end point state number of the code is set at 3 or more, and the word length of the fixed length conversion code is set at 11 bits or more. As a result, this division method is available even with respect to the codes other than the 8/10 conversion code and consists of a 7/8 conversion circuit 10 and 9/10 conversion circuit 11 which operate, based on the parallel input data of 16 bits in all and an 8-bit state decision circuit 12 and a 10-bit state deciding circuit 13 which decide the end point states of the codes outputted from the circuits 10 and 11 respectively.
Abstract:
PURPOSE:To improve close contact of master media and a slave medium at the time of transferring a magnetic signal in contact of them opposite to each other by elastically pressing both master media from their overall back surface with pressurized contact means with elastic bodies. CONSTITUTION:The device is provided with the pressurized contact means 3, each having the elastic body 4 made of a high polymer material such as a synthetic rubber having nonmagnetic elasticity formed into a discoid shape having the same radius as or larger radius than the master media 1 and the slave medium 2. The elastic bodies 4 are abutted against the overall back surfaces of the master media 1, and are given pressure in the direction as shown with arrows (a) and -a opposite to each other by arms 5 from the outside, so that both outer surfaces of the master media 1 are pressed against the slave medium 2 held between these media 1, and magnetic layers of both master media 1 and corresponding magnetic layers of both sides of the slave medium 2 are brought into pressurized contact with each other. Since the close contact is satisfactorily performed in such a way, a magnetic signal can satisfactorily be transferred with high reliability.
