摘要： The present invention provides an optical disk device that reduces a track lead-in time associated with a seek time. A switching means 50 includes a multiplier A 11 for multiplying an output of a speed control means 5 by &agr; and a multiplier B 12 for multiplying an output of a position control means 6 by (1−&agr;), and an adder 13 for adding an output of the multiplier A 11 and an output of the multiplier B 12 to output a result of the addition as control input to an actuator driving means 8. At the time of movement of an optical pickup 3 toward a target track, the multiplier factor &agr; for the multipliers A 11 and B 12 is set at 0, thereby performing control of the actuator driving means 8 by means of the position control means 6. After the optical pickup 3 reaches the vicinity of the target track, the multiplier factor &agr; is set to be gradually increased from 0 to 1 at a predetermined ratio, whereby the speed control means 5 is gradually made operate to make the lens 2 follow the eccentricity of the optical disk 1.

摘要： When a lens 4a reaches a position which is a half track short of an objective track in a track jump, a servo processor 7 conducts a braking operation of an amount corresponding to the movement velocity of the lens 4a at the timing when the lens crosses the immediately preceding track. The movement velocity of the lens 4a is detected from the period of a tracking error signal. Therefore, a phenomenon in which a braking operation is not effective and the lens overshoots the objective track is prevented from occurring, and a track-on in the objective track can be surely attained.

摘要： When an instruction to enter information unqualified for programmed reproduction is accepted, an optical disc reproducing apparatus according to the present invention gives a notification indicating that that information cannot be entered in a program. The disc detection unit 204 detects and decides a type of each optical disc, whether or not the disc can be entered in the program, and also detects the largest track number, the system controller 501 directs the disc information memory unit 502 to store the types of optical discs, information about possibility of entry in the program, and the largest track number associated with disc accommodation locations. When entering into the program the contents accepted from the operation keys on the user interface block unit 6, the system controller 501 refers to the disc information memory unit 502, and if it finds that an accepted instruction is requesting an optical disc or a track number which cannot be entered in the program, it outputs a notification indicating that the disc cannot be entered, on the display of the user interface block unit 6.

摘要： An information playback apparatus is provided to obtain sound effects by using an optical disc in much the same way an analog record is manipulated. A pressing pressure applied onto a rotatable jog dial is detected by providing a pressure sensing layer to the jog dial. When no pressing pressure is applied onto the jog dial, audio information is played back from an optical disc at a normal tempo. When an end of the jog dial at rest is pressed with a pressing pressure within a predetermined range, a tempo of a playback sound played from the audio information is changed in response to the pressing pressure. When an end of the jog dial at rest is pressed with a large pressing pressure, a tempo of a playback sound played from the audio information is changed in such a manner that playback of a playback sound is stopped eventually. When the pressing pressure is released from the jog dial at rest, a tempo of a playback sound played back from the audio information is changed in such a manner that a playback sound is eventually played back at the normal tempo. Also, a tempo of a playback sound is changed in various manners in response to a pressing pressure onto the jog dial by providing manipulation keys for adjusting a quantity of change when changing a tempo of a playback sound in response to the level of a detection signal.
摘要翻译：提供信息重放装置以通过使用光盘以与处理模拟记录的方式大致相同的方式获得声音效果。通过向微动拨盘提供压力感测层来检测施加到可旋转微动拨盘上的按压压力。当在微动拨盘上不施加按压压力时，以正常速度从光盘播放音频信息。当按压压力在预定范围内按压微动拨盘的一端时，响应于按压压力，改变从音频信息播放的重放声音的速度。当以大的按压压力按压慢跑拨盘的结束时，从音频信息播放的重放声音的速度以最终停止播放声音的方式改变。当按压压力在静止时从微动拨盘释放时，从音频信息播放的重放声音的速度以这样的方式改变，使得播放声音最终以正常速度播放。此外，响应于微动拨盘上的按压压力，通过提供用于在响应于检测信号的电平改变重放声音的速度时调节变化量的操作键，以各种方式改变播放声音的速度。

摘要： An audio reproduction apparatus randomizes or shuffles the playback order of tracks from a prerecorded media such as a compact disc within a multiple-disc changer. Shuffle sequences are generated using a linear congruential random number generator (LCRNG). The shuffle sequence does not have to be stored since a next track in the sequence can always be generated from the LCRNG using a particular set of parameters. The parameters are determined in response to the number of track (or discs) in a sequence and include elements obtained from a lookup table and elements that are randomly selected so that the same sequence is not always generated for a certain sequence length.

摘要： A method is provided for forming a body for a hard disk carriage assembly from polyphenylene sulfide 40% glass fill. An injection mold is heated to approximately 130° C.; then a volume of polyphenylene sulfide 40% glass fill is injected into the mold to form the body of the carriage assembly. The polyphenylene sulfide 40% glass fill is then cooled within the mold for approximately 45 seconds before the body is ejected from the mold cavity. The body is then heated to approximately 130° C. for at least 2 hours in a post-bake operation.
