摘要： A method of manufacturing a magnetic head slider from a flying surface pattern formed on one surface of a long and slender rectangular parallelepiped slider block having a plurality of thin film magnetic head elements aligned in a row. The method includes preparing an arrangement jig including a guide plate and an adhesive rubber plate which adheres onto a lower surface of the guide plate by its adhesive force. The method also includes placing blocks in the accommodation holes on the guide plate in such a manner that the surface of each block on which a pattern is formed is directed upward and each block is fixed by the adhesive force of the rubber plate. The rubber plate is then peeled off after an upper surface of the arrangement jig has been set upside down. Pouring and penetrating hardening liquid into clearances formed between the accommodation holes on the guide plate and the blocks is the next step. The guide plate is then fixed onto a base plate and a pattern is formed on the surface of each block.

摘要： A magnetic head unit is provided by which damage to a conductive-pattern layer formed on a spring arm during a bending process of the spring arm can be prevented. The magnetic head unit comprises a magnetic head and a spring arm having a bent portion which is bent to generate an elastic force. The magnetic head is mounted on an end of the spring arm. At least one conductive-pattern layer is formed on a surface of the spring arm to extend from a gimbal portion where the magnetic head is mounted to a attachment portion where the spring arm is mounted to a member of a magnetic head driving mechanism. The bent portion has a first portion and a second portion separated from the first portion. The conductive-pattern layer passes through the second portion. No external force is applied to the conductive-pattern layer formed during a bending process for the bent portion. A dispersing-pattern layer may be provided for dispersing an external force exerted on the conductive-pattern layer during the bending process of the bent portion so that said conductive-pattern layer is protected from being damaged due to the external force being concentrated onto said conductive-pattern layer.

摘要： An information recording and reproducing device uses a recording medium which is provided with units composed of blocks and a unit information recording area which includes unit allocation information, sector number information indicating the number of sectors per unit and unit number information identifying each unit. When the recording medium is placed in the device, the respective information is read by a calculating unit which calculates physical sector numbers corresponding to a block specified for recording and reproduction operations. Access operations are performed to the calculated sectors, which allows the desired information to be recorded. The block includes dummy sectors which are added before and after each group of predetermined numbers of effective sectors. When high-volume information is recorded over several blocks, the dummy sectors may be provided only for the first and last blocks. The device records a group of information whose volume varies from the smallest block number toward the larger block numbers, while it records a group of information whose volume is fixed from the largest block number. Thus, the recording area is effectively used. The device easily conducts the information management when a host device specifies a block. The file management may be executed by providing a unit for recording file management information separately from a unit for recording files.

摘要： An optical disk drive which discriminates whether a light spot is incident on a groove or on an area therebetween by eliminating a pulse that appears in a binary envelope signal when the light spot passes a level section. The elimination is carried out based on an ODF section detecting signal, the ODF section detecting signal being a level section detecting signal which is produced by detecting a level section (ODF section) of the optical disk. The detection is carried out by differentiating an envelope signal, which is the envelope of an electric signal corresponding to the amount of light reflected from the optical disk. Accordingly, even if the optical disk in use has interrupted grooves, the optical head can be accurately moved to a desired track located on a land or on a groove.
摘要翻译：一种光盘驱动器，其通过在光点通过电平部分时消除出现在二进制包络信号中的脉冲来鉴别光点是入射到槽还是在其上的区域。基于ODF部分检测信号进行消除，ODF部分检测信号是通过检测光盘的电平部分（ODF部分）产生的电平部分检测信号。通过对作为与从光盘反射的光量相对应的电信号的包络的包络信号进行微分来进行检测。因此，即使使用中的光盘中断了凹槽，也可以将光头精确地移动到位于台面或凹槽上的期望的轨道上。

摘要： An information recording and reproducing device uses a disk-shaped recording medium which is rotated at a constant angular velocity. The recording medium is divided into a plurality ring-shaped zones of concentric circles. In a recording area of the recording medium, the number of sectors per track is uniform in each zone and the number of sectors increases from an innermost zone towards an outermost zone. Each sector has a header area wherein header information including address information is recorded and a data area wherein data is recorded. In this device, data is recorded and reproduced in the data area in accordance with clock signals whose frequencies increase from the innermost zone towards the outermost zone. This device has a first clock generating circuit for generating a first clock signal of a fixed frequency, and the header information is recorded and reproduced in the header area in accordance with the first clock signal. This device also has a second clock generating circuit for generating a second clock signal having a frequency for recording and reproducing data which varies to correspond to the respective zones, and a control circuit for controlling the frequency of the second clock signal, according to reproduced header information, to correspond to a zone wherein data being recorded or reproduced.

摘要： An optical bar code reader includes a recognition system for recognizing a bar code data even when none of a plurality of scanning beams extend over the entire width of a bar code label. A plurality of incomplete data each of which represents a portion of the bar code label are combined with each other by a composition circuit to get an estimated complete bar code data. A determination system is provided for detecting whether the read out data obtained from any scanning beam corresponds to the entire bar code data. If an affirmative answer is obtained by the determination system, such read out data is directly applied to the associated processing system without activating the composition circuit.
