摘要： A system is provided for controlling positions of record tracks relative to a scanning trace of a head device (12A;12B). An envelope detector (36) detects an envelope of an output from a head device (12A;12B) operative to scan a record tape (13) along a scanning path transverse to record tracks. A pulse generator (40) produces two pulses appearing respectively at predetermined time points in a period of a scanning trace of the head device (12A;12B). A level sampler (37) samples a level of a detection output from the envelope detector (36) with the pulses produced by the pulse generator (40) to produce two sampled outputs. A dislocation detector (41) detects dislocation of a group of record tracks traversed by the head device (12A;12B) relative to the scanning trace of the head device (12A;12B) based on a difference between the sampled outputs from the level sampler (37). A tape controller (42,45) adjusts a travelling speed of the record tape (13) to control positions of the record tracks traversed by the head device (12A;12B) relative to the scanning trace of the head device (12A;12B) in response to a detection output from the dislocation detecting circuit (41).

摘要： A magneto-optical recording/reproducing apparatus which comprises a first optical system (1) provided with a first objective lens (2), a second optical system (21) provided with a second objective lens (22) having a numerical aperture different from that of the first objective lens, and a magnetic head (19) that is provided close to a magneto-optical recording medium for recording and is driven together with the second objective lens (22) in a body. Even when either of a first and a second magneto-optical recording medium (41, 42) having recording densities different from each other is loaded in the magneto-optical recording/reproducing apparatus, the recording or reproducing thereof is possible. Therefore, the compatibility between the first and the second magneto-optical recording medium (41, 42) is obtained.

摘要： A tape supplying and taking up apparatus is capable of use with either large or small size tape cassettes containing reels which can be of different diameters and rotated with a high degree of accuracy my means of reel spindles (51) of simple structure. Each tape cassette for use with the apparatus has a shutter (22; 45) of the slide type for closing access holes (23; 31) in the bottom wall of the cassette casing (2; 26). Each of the reel spindles (51) has a large size cassette receiving portion (52a) for receiving a tape reel of a large size tape cassette coaxial with a small size cassette receiving portion (52b) for receiving a tape reel of a small size tape cassette. The small size cassette receiving portion is smaller in diameter and disposed at a higher position than the large size cassette receiving portion. The diameter of a lower end of a reel spindle engaging hole (39) provided in each reel hub (36) of the small tape cassette is smaller than the outer diameter of the small size cassette receiving portion of the reel spindle. The reel spindle engaging hole (16) of the large size tape cassette has, at a lower end portion thereof, an escape portion which is greater in diameter than the outer diameter of the small size cassette receiving portion of the reel spindle but smaller than the outer diameter of the large size cassette receiving portion and such escape portion is higher than the height of the small size tape receiving portion.

摘要： An optical disc recording apparatus for recording information signals on an optical disc having an optical recording medium with a larger thermal time constant, such as an organic dyestuff base material, by irradiating the disc with a recording light modulated by signals produced by eight fourteen modulation of information signals, is disclosed. The apparatus includes a recording pulse forming unit for forming recording pulses from the eight fourteen modulated signals, which recording pulses are of pulse widths shorter than the eight fourteen modulated signals by a pulse width corresponding to the elongation from the regular length of a pit formed on the recording medium on the basis of the eight fourteen modulated signals, and an optical head supplied with the recording pulses formed by the pulse forming unit for producing the light which has been eight pulse width modulated by the recording pulses.

摘要： In recording/reproducing apparatus, pilot signals of different frequencies (f1 to f4) are recorded cyclically and in a predetermined sequence on parallel record tracks on a moving record medium (2) together with an information signal organised in a series of fields. The pilot signals are employed to control tracking of a reproducing head (HA,HB) of the apparatus during reproduction. During reproduction, the record medium (2) is transported at a predetermined speed and phase relative to the reproducing head (HA,HB) in order to generate reproduced pilot signals and a reproduced information signal. The reproduced pilot signals are multiplied in a multiplier (6) with reference pilot signals (REF) switched in accordance with a head switching signal (SWP), thereby generating an output from which a tracking error signal is derived. The tracking error signal is sampled and held (15) at predetermined times in a plurality of fields. A comparator (16) effects a comparison of the sampled-and-held signal with a reference signal (VREF) and produces a comparator output signal (LOC) having a state that depends on the comparison. A head clogging detector (100) is responsive to the comparator output signal (LOC) for effecting detection of a head-gap clogged condition of the reproducing head (HA,HB).
