摘要:
A storage circuit defines a first field for storing first header bits of a first payload signal of a first data unit, a second field, and a third field for storing the first payload signal. The first header bits are equal in number to second header bits of a second payload signal of a second data unit. A division circuit divides the first header bits by a generator polynomial to produce a first error check code. The same generator polynomial is used to divide the second header bits to produce a second error check code. A remainder of division of hypothetical header bits by the generator polynomial is summed to the first error check code to produce a sum which is inserted into the second field of the storage circuit. The hypothetical header bits are greater in number than a total number of bits in the first and second fields, so that the first and second data units can be distinguished from each other by different error check results of the first and second data units.

Disclosed is a magnetic disk apparatus including a magnetic reproducing head portion, and a magnetic recording head including an upper magnetic core having a end portion and a rear portion. As a resist for a frame which is used for forming the rear portion, a negative resist or an electron beam resist is used, whereby the frame is formed without any adverse effect of halation from a coil insulating film. That is, it is possible to manufacture a magnetic recording head in which the rear portion of an upper magnetic core is not emerged at the face opposed to a medium, and hence to obtain a magnetic disk apparatus exhibiting an areal recording density of 5 Gbit/in2 or more by mounting a magnetic recording/reproducing head including such a magnetic recording head.

A library apparatus of the present invention has directors which respectively determine operations of two carrying devices traveling along one traveling path. A servo control units move the carrying devices based on the determination of the directors. The serv control units obtain positional data of the carrying devices, and judge whether or not the carrying devices come into contact with each other by comparing these pieces of positional data. The servo control unit, when judging that the carrying devices come into contact with each other, stops a driving circuit of each carrying device. A drive of a motor for supplying each carrying device with power is thereby stopped, and the carrying device is stopped.

A thin film magnetic head has a first magnetic core member carried by a substrate, a gap layer formed on the first magnetic core member, and a second magnetic core member formed in a spaced relation with the first magnetic core member. The second magnetic core member is coupled to the first magnetic core member to form a magnetic path and to have an end portion of the gap layer sandwiched by gap defining portions of the first and second magnetic core members. A coil conductor is wound about the magnetic path. In one embodiment, the first magnetic core member includes a first magnetic layer made of a magnetic material having stable magnetic properties during heat treatment and the second magnetic core member includes a second magnetic layer made of a material having a saturation flux density higher than that of the material of the first magnetic core member.

A CPU of a personal computer operates as a driver of a color printer main body in accordance with software processing based on a printer driver program installed in a hard disk unit. Then, in the driver operation, the CPU determines whether or not an application requesting printing carries out application ICM. Further, the CPU causes a printer to execute printer ICM only in the case where the application ICM is set OFF, and the printer ICM is set to ON in consideration of the result of the determining and user setting of ON/OFF of the printer ICM accepted in advance.

A magnetic disk apparatus includes a magnetic reproducing head portion, and a magnetic recording head including a lower magnetic core and an upper magnetic core having a end portion and a rear portion. The rear portion is formed using a negative resist or an electron beam resist to form a frame for plating above the end portion of the upper magnetic core head.
