摘要： An information recording and reproducing apparatus employs a magneto-optical disk including a main information recording area wherein plural pieces of main information can be recorded and a TOC area wherein control information related to each piece of main information can be recorded. When a reproducing operation cannot be performed from the TOC area, it is checked whether or not any pieces of control information exist, for example, by detecting an amplitude of a reproduced signal. Or, whether or not a recording or reproducing function of the apparatus works properly may be checked by, for example, a method of test writing and reproduction. As a result, whether or not the magneto-optical disk is a blank disk can be accurately determined. Further, when the disk is determined to be a blank disk, distinctive information indicating a blank disk is recorded in a predetermined portion of the TOC area. Thereafter, upon loading the disk, the disk is promptly determined to be a blank disk. On the other hand, when the disk is not determined to be a blank disk, at least a recording operation is inhibited, thereby eliminating a possibility of destroying useful main information already recorded in the main information recording area.
摘要翻译：信息记录和再现装置采用包括可以记录多条主信息的主信息记录区的磁光盘和可记录与每条主信息相关的控制信息的TOC区。当不能从TOC区域执行再现操作时，例如通过检测再现信号的幅度来检查是否存在任何控制信息。或者，可以通过例如测试写入和再现的方法来检查设备的记录或再现功能是否正常工作。结果，可以准确地确定磁光盘是否为空盘。此外，当确定盘是空白盘时，指示空白盘的特征信息被记录在TOC区域的预定部分中。此后，在加载磁盘时，迅速地将磁盘确定为空白磁盘。另一方面，当盘不被确定为空盘时，至少禁止记录操作，从而消除了已经记录在主信息记录区中的有用主信息的可能性。

摘要： An information recording and reproducing device has a first recording clock generation circuit which generates a clock based on pre-recorded information on a magneto-optical disk, a second recording clock generation circuit and a switching circuit The switching circuit selects a first recording clock when recording information is of discrete information and selects a second recording clock when recording information is of successive information. Moreover, in the present device, a first reading clock is used as well as a second clock as a clock for reading out the reproduced data from the magneto-optical disk, which had been once stored in memory. The second reading clock having a reference frequency is generated by a second clock generation circuit and is used for reading out successive information such as music information. The first reading clock in synchronization with the reproduced signal is generated by a first reading clock generation circuit and is used for reading out discrete information such as computer-use data. In addition, in the case of discrete information, it is possible to start recording/reproducing operation immediately after an optical head reaches a desired position, thereby permitting to shorten an access time.

摘要： An electromagnetic field generating element restrains magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for thermally assisted magnetic field recording/reproduction using a near field. An information recording/reproducing head and an information recording/reproducing apparatus carry out high frequency magnetic recording/reproduction. The electromagnetic field generating element includes: (i) a substrate, (ii) conductors each provided on the substrate and each serving as a supporting section, (iii) a plate-like-shaped conductor provided on the conductors and (iv) a semiconductor laser element provided on the substrate. The semiconductor laser element irradiates laser light to the plate-like-shaped conductor substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of a near field in the plate-like-shaped conductor. In addition, a magnetic field is generated by supplying a current to the plate-like-shaped conductor.

摘要： An automatic tool changing method and an automatic tool changing device for a machine tool with a numerical controller capable of reducing the occurrence of impact due to tool exchange with a simple structure. A turret that rotates about a pivot shaft is provided on an arm and holds multiple tools. A swing cam CS that cooperates with a swing roller provided on the turret is provided on a spindle head. As the spindle head descends the turret rotates due to the action of the swing roller and the cam CS and exchanges tools. In order to lessen the impact that occurs at this time, the velocity of the spindle head is controlled. The ideal swing velocity pattern for the turret is obtained, and from this swing velocity pattern the swing position of the turret at each moment is obtained. From the swing roller and cam CS positions at this position the position of the spindle head 34 is obtained. From the acquired spindle head position the spindle head velocity pattern is obtained, and the spindle head is controlled using this velocity pattern. As a result, an ideal swing pattern can be achieved, and therefore no impact arises.

摘要： A spindle motor as a heating element and a spindle head having a spindle that is driven by the spindle motor are coupled to each other by a cooling flange. The cooling flange is provided with a cooling passage, the cross-sectional area of which gradually increases with distance from its gas inlet toward its gas outlet. When a high-pressure gas is injected into the cooling passage through the gas inlet, it is adiabatically expanded and cooled by the cooling passage having the gradually increasing cross-sectional area. Thus, the cooling flange restrains heat generated from the spindle motor from being transmitted to the spindle head.
